By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the library's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The main changes over version 2 include:</p> +<ul> +<li>Both fragmented and unfragmented messages contain sender and +recipient instance tags. This avoids an issue on IM networks that +always relay all messages to all sessions of a client who is logged +in multiple times. In this situation, OTR clients can attempt to +establish an OTR session indefinitely if there are interleaving +messages from each of the sessions.</li> +<li>An extra symmetric key is derived during AKE. This may be used for +secure communication over a different channel (e.g., file transfer, +voice chat).</li> +</ul> +<h2>Very high level overview</h2> +<p>OTR assumes a network model which provides in-order delivery of +messages, but that some messages may not get delivered at all +(for example, if the user disconnects). There may be +an active attacker, who is allowed to perform a Denial of +Service attack, but not to learn the contents of messages.</p> +<ol> +<li>Alice signals to Bob that she would like (using an OTR Query Message) +or is willing (using a whitespace-tagged plaintext message) to use OTR +to communicate. Either mechanism should convey the version(s) of OTR +that Alice is willing to use.</li> +<li>Bob initiates the authenticated key exchange (AKE) with Alice. +Versions 2 and 3 of OTR use a variant of the SIGMA protocol as its AKE.</li> +<li>Alice and Bob exchange Data Messages to send information to each +other.</li> +</ol> +<h2>High level overview</h2> +<h3>Requesting an OTR conversation</h3> +<p>There are two ways Alice can inform Bob that she is willing to use +the OTR protocol to speak with him: by sending him the OTR Query Message, +or by including a special "tag" consisting of whitespace characters in +one of her messages to him. Each method also includes a way for Alice +to communicate to Bob which versions of the OTR protocol she is willing +to speak with him.</p> +<p>The semantics of the OTR Query Message are that Alice is +<em>requesting</em> that Bob start an OTR conversation with her (if, of +course, he is willing and able to do so). On the other hand, the +semantics of the whitespace tag are that Alice is merely +<em>indicating</em> to Bob that she is willing and able to have an OTR +conversation with him. If Bob has a policy of "only use OTR when it's +explicitly requested", for example, then he <em>would</em> start an OTR +conversation upon receiving an OTR Query Message, but <em>would not</em> +upon receiving the whitespace tag.</p> +<h3>Authenticated Key Exchange (AKE)</h3> +<p>This section outlines the version of the SIGMA protocol used as the +AKE. All exponentiations are done modulo a particular 1536-bit prime, +and g is a generator of that group, as indicated in the detailed +description below.

The +version string is constructed as follows:</p> +<ul> +<li>If she is willing to use OTR version 1, the version string must +start with "?".</li> +<li>If she is willing to use OTR versions other than 1, a "v" followed +by the byte identifiers for the versions in question, followed by "?". +The byte identifier for OTR version 2 is "2", and similarly for 3. The +order of the identifiers between the "v" and the "?" does not matter, +but none should be listed more than once.</li> +</ul> +<p>For example:</p> +<dl> +<dt>"?OTR?"</dt> +<dd>Version 1 only</dd> +<dt>"?OTRv2?"</dt> +<dd>Version 2 only</dd> +<dt>"?OTRv23?"</dt> +<dd>Versions 2 and 3</dd> +<dt>"?OTR?v2?"</dt> +<dd>Versions 1 and 2</dd> +<dt>"?OTRv24x?"</dt> +<dd>Version 2, and hypothetical future versions identified by "4" and +"x"</dd> +<dt>"?OTR?v24x?"</dt> +<dd>Versions 1, 2, and hypothetical future versions identified by "4" and +"x"</dd> +<dt>"?OTR?v?"</dt> +<dd>Also version 1 only</dd> +<dt>"?OTRv?"</dt> +<dd>A bizarre claim that Alice would like to start an OTR conversation, +but is unwilling to speak any version of the protocol</dd> +</dl> +<p>These strings may be hidden from the user (for example, in +an attribute of an HTML tag), and/or may be accompanied by an +explanitory message ("Alice has requested an Off-the-Record private +conversation."). If Bob is willing to use OTR with Alice (with a +protocol version that Alice has offered), he should start the AKE.</p> +<h4>Tagged plaintext messages</h4> +<p>If Alice wishes to communicate to Bob that she is willing to use OTR, +she can attach a special whitespace tag to any plaintext message she +sends him. This tag may occur anywhere in the message, and may be +hidden from the user (as in the Query Messages, above).</p> +<p>The tag consists of the following 16 bytes, followed by one or more +sets of 8 bytes indicating the version of OTR Alice is willing to +use:</p> +<ul> +<li>Always send "\x20\x09\x20\x20\x09\x09\x09\x09" +"\x20\x09\x20\x09\x20\x09\x20\x20", followed by one or more of:</li> +<li>"\x20\x09\x20\x09\x20\x20\x09\x20" to indicate a willingness to use +OTR version 1 with Bob (note: this string must come before all other +whitespace version tags, if it is present, for backwards +compatibility)</li> +<li>"\x20\x20\x09\x09\x20\x20\x09\x20" to indicate a willingness to use +OTR version 2 with Bob</li> +<li>"\x20\x20\x09\x09\x20\x20\x09\x09" to indicate a willingness to use +OTR version 3 with Bob</li> +</ul> +<p>If Bob is willing to use OTR with Alice (with a protocol version that +Alice has offered), he should start the AKE. On the other hand, if +Alice receives a plaintext message from Bob (rather than an initiation +of the AKE), she should stop sending him the whitespace tag.</p> +<h4>OTR Error Messages</h4> +<p>Any message containing the string "?OTR Error:" is an OTR Error +Message. The following part of the message should contain +human-readable details of the error.</p> +<h3>Encoded messages</h3> +<p>This section describes the byte-level format of the base-64 encoded +binary OTR messages. The binary form of each of the messages is +described below.

The current version of +the OTR protocol only supports DSA public keys, but there is a key type +marker for future extensibility.</p> +<dl> +<dt>OTR public authentication DSA key (PUBKEY):</dt> +<dd>Pubkey type (SHORT) +<ul class="note"><li>DSA public keys have type 0x0000</li></ul> +p (MPI) +<br />q (MPI) +<br />g (MPI) +<br />y (MPI) +<ul class="note"><li>(p,q,g,y) are the DSA public key parameters</li></ul> +</dd> +</dl> +<p>OTR public keys are used to generate <b>signatures</b>; different +types of keys produce signatures in different formats. The format for a +signature made by a DSA public key is as follows:</p> +<dl> +<dt>DSA signature (SIG):</dt> +<dd> (len is the length of the DSA public parameter q, which in +current implementations must be 20 bytes, or 160 bits) +<br /> len byte unsigned r, big-endian +<br /> len byte unsigned s, big-endian</dd> +</dl> +<p>OTR public keys have <b>fingerprints</b>, which are hex strings that +serve as identifiers for the public key. The fingerprint is calculated +by taking the SHA-1 hash of the byte-level representation of the public +key. However, there is an exception for backwards compatibility: if the +pubkey type is 0x0000, those two leading 0x00 bytes are omitted from the +data to be hashed. The encoding assures that, assuming the hash +function itself has no useful collisions, and DSA keys have length less +than 524281 bits (500 times larger than most DSA keys), no two public +keys will have the same fingerprint.</p> +<h4>Instance Tags</h4> +<p>Clients include instance tags in all OTR version 3 messages. Instance +tags are 32-bit values that are intended to be persistent. If the same +client is logged into the same account from multiple locations, the +intention is that the client will have different instance tags at each +location. As shown below, OTR version 3 messages (fragmented and +unfragmented) include the source and destination instance tags. If a client +receives a message that lists a destination instance tag different from its +own, the client should discard the message.</p> +<p>The smallest valid instance tag is 0x00000100. It is appropriate to set the +destination instance tag to '0' when an actual destination instance tag is +not known at the time the message is prepared. If a client receives a +message with the sender instance tag set to less than 0x00000100, it should +discard the message. Similarly, if a client receives a message with the +recipient instance tag set to greater than 0 but less than 0x00000100, it +should discard the message. +</p> + +<p>This avoids an issue on IM networks that always relay all messages to +all sessions of a client who is logged in multiple times. In this +situation, OTR clients can attempt to establish an OTR session indefinitely +if there are interleaving messages from each of the sessions.</p> +<h4>D-H Commit Message</h4> +<p>This is the first message of the AKE. Bob sends it to Alice to +commit to a choice of D-H encryption key (but the key itself is not yet +revealed).

The protocol used by OTR is +based on the work of Boudot, Schoenmakers and Traore (2001). A full +justification for its use in OTR is made by Alexander and Goldberg, +in a paper published in 2007. The following is a technical account +of what is transmitted during the course of the protocol.</p> +<h4>Secret information</h4> +<p>The secret information x and y compared during this protocol contains +not only information entered by the users, but also information unique to +the conversation in which SMP takes place. Specifically, the format is:</p> +<dl> +<dt>Version (BYTE)</dt> +<dd>The version of SMP used. The version described here is 1.</dd> +<dt>Initiator fingerprint (20 BYTEs)</dt> +<dd>The fingerprint that the party initiating SMP is using in +the current conversation.</dd> +<dt>Responder fingerprint (20 BYTEs)</dt> +<dd>The fingerprint that the party that did not initiate SMP is +using in the current conversation.</dd> +<dt>Secure Session ID</dt> +<dd>The ssid described below.</dd> +<dt>User-specified secret</dt> +<dd>The input string given by the user at runtime.</dd> +</dl> +<p>Then the SHA256 hash of the above is taken, and the digest becomes the +actual secret (x or y) to be used in SMP. The additional fields insure +that not only do both parties know the same secret input string, but no +man-in-the-middle is capable of reading their communication either.</p> +<h3>The SMP state machine</h3> +<p>Whenever the OTR message state machine has MSGSTATE_ENCRYPTED set +(see below), the SMP state machine may progress. If at any point +MSGSTATE_ENCRYPTED becomes unset, SMP must abandon its state and return +to its initial setup.

This in done to allow the +forgeability of OTR transcripts: once the MAC keys are revealed, anyone +can modify an OTR message and still have it appear valid. But since we +don't reveal the MAC keys until their corresponding pubkeys are being +discarded, there is no danger of accepting a message as valid which +uses a MAC key which has already been revealed.</p> +<h3>Fragmentation</h3> +<p>Some networks may have a maximum message size that is too small to +contain an encoded OTR message.

For +example, Alice may have an active OTR conversation with Bob, while +having an unprotected conversation with Charlie. This state consists of +two main state variables, as well as some other information (such as +encryption keys). The two main state variables are:</p> +<h4>Message state</h4> +<p>The message state variable, msgstate, controls what happens to +outgoing messages typed by the user. It can take one of three +values:</p> +<dl> +<dt>MSGSTATE_PLAINTEXT</dt> +<dd>This state indicates that outgoing messages are sent without +encryption. This is the state that is used before an OTR conversation +is initiated. This is the initial state, and the only way to +subsequently enter this state is for the user to explicitly request to +do so via some UI operation.</dd> +<dt>MSGSTATE_ENCRYPTED</dt> +<dd>This state indicates that outgoing messages are sent encrypted. +This is the state that is used during an OTR conversation. The only way +to enter this state is for the authentication state machine (below) to +successfully complete.</dd> +<dt>MSGSTATE_FINISHED</dt> +<dd>This state indicates that outgoing messages are not delivered at +all. This state is entered only when the other party indicates he has +terminated his side of the OTR conversation. For example, if Alice and +Bob are having an OTR conversation, and Bob instructs his OTR client to +end its private session with Alice (for example, by logging out), Alice +will be notified of this, and <em>her</em> client will switch to +MSGSTATE_FINISHED mode. This prevents Alice from accidentally sending a +message to Bob in plaintext. (Consider what happens if Alice was in the +middle of typing a private message to Bob when he suddenly logs out, +just as Alice hits Enter.)</dd> +</dl> +<h4>Authentication state</h4> +<p>The authentication state variable, authstate, can take one of four +values (plus one extra for OTR version 1 compatibility):</p> +<dl> +<dt>AUTHSTATE_NONE</dt> +<dd>This state indicates that the authentication protocol is not +currently in progress. This is the initial state.</dd> +<dt>AUTHSTATE_AWAITING_DHKEY</dt> +<dd>After Bob initiates the authentication protocol by sending Alice +the D-H Commit Message, he enters this state to await Alice's reply.</dd> +<dt>AUTHSTATE_AWAITING_REVEALSIG</dt> +<dd>After Alice receives Bob's D-H Commit Message, and replies with her +own D-H Key Message, she enters this state to await Bob's reply.</dd> +<dt>AUTHSTATE_AWAITING_SIG</dt> +<dd>After Bob receives Alice's D-H Key Message, and replies with his own +Reveal Signature Message, he enters this state to await Alice's reply.</dd> +<dt>AUTHSTATE_V1_SETUP</dt> +<dd>For OTR version 1 compatibility, if Bob sends a version 1 Key +Exchange Message to Alice, he enters this state to await Alice's +reply.</dd> +</dl> +<p>After:</p> +<ul> +<li>Alice (in AUTHSTATE_AWAITING_REVEALSIG) receives Bob's Reveal +Signature Message (and replies with her own Signature Message), <b>or</b> +</li> +<li>Bob (in AUTHSTATE_AWAITING_SIG) receives Alice's Signature Message, +/li> +</ul> +<p>then, +assuming the signature verifications succeed, the msgstate +variable is transitioned to MSGSTATE_ENCRYPTED. Regardless of whether +the signature verifications succeed, the authstate variable is +transitioned to AUTHSTATE_NONE.</p> +<h4>Policies</h4> +<p>OTR clients can set different <b>policies</b> for different +correspondents. For example, Alice could set up her client so that it +speaks only OTR version 3, except with Charlie, who she knows has only +an old client; so that it will opportunistically start an OTR conversation +whenever it detects the correspondent supports it; or so that it refuses +to send non-encrypted messages to Bob, ever.</p> +<p>The policies that can be set (on a global or per-correspondent basis) +are any combination of the following boolean flags:</p> +<dl> +<dt>ALLOW_V1</dt> +<dd>Allow version 1 of the OTR protocol to be used (in general this +document will not address OTR protocol version 1; see previous +protocol documents for these details).</dd> +<dt>ALLOW_V2</dt> +<dd>Allow version 2 of the OTR protocol to be used.</dd> +<dt>ALLOW_V3</dt> +<dd>Allow version 3 of the OTR protocol to be used.</dd> +<dt>REQUIRE_ENCRYPTION</dt> +<dd>Refuse to send unencrypted messages.</dd> +<dt>SEND_WHITESPACE_TAG</dt> +<dd>Advertise your support of OTR using the whitespace tag.</dd> +<dt>WHITESPACE_START_AKE</dt> +<dd>Start the OTR AKE when you receive a whitespace tag.</dd> +<dt>ERROR_START_AKE</dt> +<dd>Start the OTR AKE when you receive an OTR Error Message.</dd> +</dl> +<p>Note that it is possible for UIs simply to offer the old +"combinations" of options, and not ask about each one separately.</p> +<h4>State transitions</h4> +<p>There are twelve actions an OTR client must handle:</p> +<ul> +<li>Received messages: +<ul> +<li>Plaintext without the whitespace tag</li> +<li>Plaintext with the whitespace tag</li> +<li>Query Message</li> +<li>Error Message</li> +<li>D-H Commit Message</li> +<li>D-H Key Message</li> +<li>Reveal Signature Message</li> +<li>Signature Message</li> +<li>Data Message</li> +</ul></li> +<li>User actions: +<ul> +<li>User requests to start an OTR conversation</li> +<li>User requests to end an OTR conversation</li> +<li>User types a message to be sent</li> +</ul></li> +</ul> +<p>The following sections will outline what actions to take in each +case.

Anyone can forge messages after a + conversation to make them look like they came from you. However, + _during_ a conversation, your correspondent is assured the messages + he sees are authentic and unmodified. + - Perfect forward secrecy + - If you lose control of your private keys, no previous conversation + is compromised. + +For more information on Off-the-Record Messaging, see +https://otr.cypherpunks.ca/ + +LIBRARY USAGE + +1. Initialization + +Before you call any other libotr routine, you need to initialize the +library. The easiest way to do that is to include proto.h, and use the +macro: + + OTRL_INIT; + +somewhere early in your program. This should be called only once. + +You will also need an OtrlUserState. An OtrlUserState encapsulates the +list of known fingerprints and the list of private keys, so it should be +"one per user". Many OTR-enabled programs (such as IM clients) only have a +single user, so for them, you can just create a single one, and use it +throughout. Create an OtrlUserState as follows: + + userstate = otrl_userstate_create(); + +If you need to free an OtrlUserState: + + otrl_userstate_free(userstate); + +To read stored private keys: + + otrl_privkey_read(userstate, privkeyfilename); + +To read stored instance tags: + + otrl_instag_read(userstate, instagfilename); + +To read stored fingerprints: + + otrl_privkey_read_fingerprints(userstate, fingerprintfilename, + add_app_info, add_app_info_data); + +add_app_info is a function that will be called in the event that a new +ConnContext is created. It will be passed the add_app_info_data that +you supplied, as well as a pointer to the new ConnContext. You can use +this to add application-specific information to the ConnContext using +the "context->app" field, for example. If you don't need to do this, +you can pass NULL for the last two arguments of +otrl_privkey_read_fingerprints. + +2. Setting up the UI functions + +You need to let the library know how to do any UI it might require +(error messages, confirming new fingerprints, etc.). To this end, you +need to define a number of UI functions, and collect them in a +OtrlMessageAppOps struct. + +The first parameter of every UI function is "void *opdata". This is a +pointer you pass to the library, and it will pass back (opaquely) to the +UI functions when it calls them. You can use this to keep track of +state or any other information. + +You will need to include proto.h and message.h, and you can find a list +of the UI functions in message.h. + +3. Sending messages + +When you have a message you're about to send, you'll need to know four +things: you account name, the protocol id, the name of the recipient, +their instance tag, and the message. + +OTR protocol version 3 introduces the notion of "instance tags." A +client may be logged into the same account multiple times from different +locations. An instance tag is intended to differentiate these clients. +When sending a message, you may also specify a particular instance tag, +or use meta instance tags like OTRL_INSTAG_MOST_SECURE. + +The protocol id is just a unique string that is used to distinguish +the user foo on AIM from the user foo on MSN, etc. It can be anything +you like, so long as you're consistent, but if you've got nothing better +to use, you may as well use the ids from gaim. (Programs that use the +same protocol ids can share fingerprint and private key files.) The +gaim protocol id for AIM/ICQ is "prpl-oscar". + +Note that a name does not uniquely identify a user (as shown by the +"foo" example above). Even if you know both the name and the protocol, +it may not identify the user, since there may be multiple "foo" users on +IRC, on different servers. But the *three* items (your account name, +protocol id, their name) _must_ uniquely identify a user, so your +account name needs to include any network identifier, such as a server +name. Examples would be "foo@irc.freenode.net" or "foo@jabber.org". +Protocols such as AIM that do not have separate networks can just use +"foo", of course. + +To encrypt the message (if necessary; the library keeps track of which +users you have secure connections to, so you should *always* call this +next function), simply do this: + + gcry_error_t err; + char *newmessage = NULL; + + err = otrl_message_sending(userstate, &ui_ops, opdata, accountname, + protocolid, recipient_name, instag, message, tlvs, + &newmessage, fragPolicy, contextp, add_app_info, + add_app_info_data); + +add_app_info and add_app_info_data are as above, and may be NULL. + +tlvs should usually be NULL. If it's not, then it points to a chain of +OtrlTLVs which represent machine-readable data to send along with this +message. + +If contextp is not NULL, it will be set to the context that was used +for sending the message. + +If err is non-zero, then the library tried to encrypt the message, +but for some reason failed. DO NOT send the message in the clear in +that case. + +If newmessage gets set by the call to something non-NULL, then you +should replace your message with the contents of newmessage, and +send that instead. + +Once the message is encrypted, it may still be too large to send over +the network in a single piece. To check the maximum message size and +break your message into fragments if necessary, do this: + + gcry_error_t err; + char *extrafragment = NULL; + + err = otrl_message_fragment_and_send(&ui_ops, opdata, context, + message, fragmentPolicy, extrafragment); + +fragmentPolicy determines which, if any, fragments to return instead +of sending them immediately. For example, you may wish to send all +fragments except the last one, which is handled differently. Valid +policies may be found in proto.h. + +If err returns a nonzero value from fragment_and_send, the application +tried to break your message into fragments but failed for some reason. +You may still attempt to send the original message, but it might be +rejected if it too large. + +When you're done with newmessage, you must call + + otrl_message_free(newmessage) + +4. Receiving messages + +Receiving messages is similarly straightforward. Again, you need to +know four things: your account name, the protocol id, the sender's name, +and the message. + + int ignore_message; + char *newmessage = NULL; + + ignore_message = otrl_message_receiving(userstate, &ui_ops, opdata, + accountname, protocolid, sender_name, message, &newmessage, + &tlvs, contextp, add_app_info, add_app_info_data); + +add_app_info and add_app_info_data are as above, and may be NULL. + +If contextp is not NULL, it will be set to the context that was used +for receiving the message. + +If otrl_message_receiving returns 1, then the message you received was +an internal protocol message, and no message should be delivered to the +user. + +If it returns 0, then check if newmessage was set to non-NULL. If so, +replace the received message with the contents of newmessage, and +deliver that to the user instead. You must call +otrl_message_free(newmessage) when you're done with it. + +If otrl_message_receiving returns 0 and newmessage is NULL, then this +was an ordinary, non-OTR message, which should just be delivered to the +user without modification. + +If tlvs is set to non-NULL, then there is machine-readable data that was +sent along with this message. Call otrl_tlv_free(tlvs) when you're done +dealing with it (or ignoring it). + +5. Socialist Millionaires' Protocol + +The Socialist Millionaires' Protocol (SMP) is a way to detect +eavesdropping and man-in-the-middle attacks without requiring users to +work with fingerprints. This feature was added to OTR starting in +version 3.1.0. To learn how to modify your application to use SMP, read +the UPGRADING file. + +TOOLKIT + +Along with the library, this package comes with the OTR Messaging +Toolkit. This toolkit is useful for analyzing and/or forging OTR +messages. Why do we offer this? Primarily, to make absolutely sure +that transcripts of OTR conversations are really easy to forge after the +fact. [Note that *during* an OTR conversation, messages can't be forged +without real-time access to the secret keys on the participants' +computers, and in that case, all security has already been lost.] +Easily forgeable transcripts help us provide the "Deniability" property: +if someone claims you said something over OTR, they'll have no proof, as +anyone at all can modify a transcript to make it say whatever they like, +and still have all the verification come out correctly. + +Here are the six programs in the toolkit: + + - otr_parse + - Parse OTR messages given on stdin, showing the values of all the + fields in OTR protocol messages. + + - otr_sesskeys our_privkey their_pubkey + - Shows our public key, the session id, two AES and two MAC keys + derived from the given Diffie-Hellman keys (one private, one public). + + - otr_mackey aes_enc_key + - Shows the MAC key derived from the given AES key. + + - otr_readforge aes_enc_key [newmsg] + - Decrypts an OTR Data message using the given AES key, and displays + the message, if the key was correct. + - If newmsg is given, replace the message with that one, encrypt + and MAC it properly, and output the resulting OTR Data Message. + This works even if the given key was not correct for the original + message, so as to enable complete forgeries. + + - otr_modify mackey old_text new_text offset + - Even if you can't read the data because you don't know either + the AES key or the Diffie-Hellman private key, but you can make a + good guess that the substring "old_text" appears at the given + offset in the message, replace the old_text with the new_text + (which must be of the same length), recalculate the MAC with the + given mackey, and output the resulting Data message. + - Note that, even if you don't know any text in an existing message, + you can still forge messages of your choice using the otr_readforge + command, above. + + - otr_remac mackey sender_instance receiver_instance flags keyid keyid + pubkey counter encdata revealed_mackeys + - Make a new OTR Data Message, with the given pieces (note that the + data part is already encrypted). MAC it with the given mackey. + +NOTES + +Please send your bug reports, comments, suggestions, patches, etc. to us +at the contact address below. + +In otrl_message_sending, specifying an instance tag allows you to send a +message to a particular session of a buddy who is logged in multiple times +with an otr-enabled client. The OTRL_INSTAG_RECENT_RECEIVED meta-instance +relies on the time that libotr processed the most recent message. Meta- +instance tags resolve to actual instance tags before a message is sent. An +instant messaging network may not agree on which session of the remote party is +the most recent, e.g., due to underlying network race conditions. If the +behaviour of an instant messaging network is to only deliver to the most recent, +and libotr and the network disagree on which session is the most recent, the +other party will not process the given message. That is, the instant messaging +network will deliver the message to the session whose actual instance tag does +not match the addressed instance tag. Also note that OTRL_INSTAG_BEST also +prefers more recent instance tags in the case of multiple instances with the +same "best" status (most secure). In this case, the most recent has a +resolution of one second. + +If otrl_message_sending is called with an original_msg that contains the text +"?OTR?", this is a signal to initiate or refresh an OTR session. There is +currently no way to indicate if this text was actually typed in by a user and +part of a conversation (e.g., someone communicating instructions on how to +refresh OTR). In the future, we may allow a policy to specify whether "?OTR?" +is a signal to start OTR, or just an ordinary message for encrypted and +unencrypted conversations. + +MAILING LISTS + +There are three mailing lists pertaining to Off-the-Record Messaging: + +otr-announce: + https://lists.cypherpunks.ca/mailman/listinfo/otr-announce/ + *** All users of OTR software should join this. *** It is used to + announce new versions of OTR software, and other important information. + +otr-users: + https://lists.cypherpunks.ca/mailman/listinfo/otr-users/ + Discussion of usage issues related to OTR Messaging software. + +otr-dev: + https://lists.cypherpunks.ca/mailman/listinfo/otr-dev/ + Discussion of OTR Messaging software development. + +LICENSE + +The Off-the-Record Messaging library (in the src directory) is +covered by the following (LGPL) license: + + Off-the-Record Messaging library + Copyright (C) 2004-2016 Ian Goldberg, David Goulet, Rob Smits, + Chris Alexander, Willy Lew, Lisa Du, + Nikita Borisov + <otr@cypherpunks.ca> + + This library is free software; you can redistribute it and/or + modify it under the terms of version 2.1 of the GNU Lesser General + Public License as published by the Free Software Foundation. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Asynchronous Private Key Generation +3.5. Library Initialization + +1. Introduction + +This file contains information about the changes between the 3.2.0 and +the 4.0.0 APIs for libotr. Note that applications compiled against +previous versions of OTR will not work with libotr 4.0.0. + +2. Major Additions + +This section describes the new features in OTR 4.0.0 along with a short +history or motivation for each. + +2.1. Instance Tags + +Clients generate instance tags that are intended to be persistent. If +the same client is logged into the same account from multiple locations, +the intention is that he or she will have different instance tags at +each location. OTR wire messages (fragmented and unfragmented) include +the source and destination instance tags. If a client receives a message +that lists a destination instance tag different from his own, the client +will discard it (and issue a callback notifying the application of the +event). + +This avoids an issue on IM networks that always relay all messages to +all sessions of a client who is logged in multiple times. In this +situation, OTR clients can attempt to establish an OTR session +indefinitely if there are interleaving messages from each of the +sessions. + +2.2. Asynchronous Private Key Generation + +Key generation can happen in a separate thread without blocking an +application. + +2.3. Extra Symmetric Key + +An extra symmetric key is kept synchronized during a conversation with a +buddy. Either side can send a signal that they wish to use this key for +some external purpose (e.g. things like a file transfer, in some other +channel of communication). + +2.4. Convert Operations + +There is now a callback that is made immediately before a message is +encrypted and immediately after a message is decrypted. This callback +can tweak the plaintext message as needed. For example, this could allow +an application to convert formatting on a message if this would normally +be done on the plaintext by some other entity while the message is in +transit. + +2.5. SMP, Error, and Message Event Callbacks + +To avoid hard-coded English phrases in libotr, operations which used to +pass back strings are replaced by operations that pass back event codes. + +2.6. Fragmentation Changes + +In libotr version 3.2.0, you would need to call otrl_message_sending() +to create an encrypted message, and then call fragment_and_send() to get +libotr to fragment and inject that message. In libotr 4.0.0, the +functionality of fragment_and_send() has been integrated into +otrl_message_sending(). + +3. Required Changes + +3.1. OtrlMessageAppOps Callbacks + +3.1.1. Removed Operations + +/* Display a notification message for a particular accountname / + * protocol / username conversation. */ +void (*notify)(void *opdata, OtrlNotifyLevel level, + const char *accountname, const char *protocol, + const char *username, const char *title, + const char *primary, const char *secondary); + +The notify() operation was removed since it was used to pass in +hardcoded English strings. This has been replaced by error and message +event callbacks, described below, which pass event codes rather than +hardcoded strings. + + +/* Display an OTR control message for a particular accountname / + * protocol / username conversation. Return 0 if you are able to + * successfully display it. If you return non-0 (or if this + * function is NULL), the control message will be displayed inline, + * as a received message, or else by using the above notify() + * callback. */ +int (*display_otr_message)(void *opdata, const char *accountname, + const char *protocol, const char *username, const char *msg); + +The display_otr_message() operation was removed for the same reasons as +above for the notify() operation. + + +/* Return a newly allocated string containing a human-friendly name + * for the given protocol id */ +const char *(*protocol_name)(void *opdata, const char *protocol); + +/* Deallocate a string allocated by protocol_name */ +void (*protocol_name_free)(void *opdata, const char *protocol_name); + +The above operations are no longer required, as they were used when +preparing messages shown to users. + + +/* Log a message. The passed message will end in "\n". */ +void (*log_message)(void *opdata, const char *message); + +The log_message() operation was also replaced by message event +callbacks. + +3.1.2. Added Operations + +/* We received a request from the buddy to use the current "extra" + * symmetric key. The key will be passed in symkey, of length + * OTRL_EXTRAKEY_BYTES. The requested use, as well as use-specific + * data will be passed so that the applications can communicate other + * information (some id for the data transfer, for example). */ +void (*received_symkey)(void *opdata, ConnContext *context, + unsigned int use, const unsigned char *usedata, + size_t usedatalen, const unsigned char *symkey); + +This is called when a remote buddy has specified a use for the current +symmetric key. If your application does not use the extra symmetric key +it does not need to provide an implementation for this operation. + + +/* Return a string according to the error event. This string will then + * be concatenated to an OTR header to produce an OTR protocol error + * message. The following are the possible error events: + * - OTRL_ERRCODE_ENCRYPTION_ERROR + * occured while encrypting a message + * - OTRL_ERRCODE_MSG_NOT_IN_PRIVATE + * sent encrypted message to somebody who is not in + * a mutual OTR session + * - OTRL_ERRCODE_MSG_UNREADABLE + * sent an unreadable encrypted message + * - OTRL_ERRCODE_MSG_MALFORMED + * message sent is malformed */ +const char *(*otr_error_message)(void *opdata, ConnContext *context, + OtrlErrorCode err_code); + +/* Deallocate a string returned by otr_error_message */ +void (*otr_error_message_free)(void *opdata, const char *err_msg); + +These methods are for producing human-readable error message that will +be sent to the remote buddy when one of these error conditions occurs. +They will be appended to the string "?OTR Error: ". Implementing this +operation is not required, but depending on your application it may be a +good idea. + + +/* Return a string that will be prefixed to any resent message. If this + * function is not provided by the application then the default prefix, + * "[resent]", will be used. + * */ +const char *(*resent_msg_prefix)(void *opdata, ConnContext *context); + +/* Deallocate a string returned by resent_msg_prefix */ +void (*resent_msg_prefix_free)(void *opdata, const char *prefix); + +These operations give the option of chosing an alternative to the +English string "[resent]", when a message is resent. + + +/* Update the authentication UI with respect to SMP events + * These are the possible events: + * - OTRL_SMPEVENT_ASK_FOR_SECRET + * prompt the user to enter a shared secret.

If you application is +implementing support for SMP authentication it should handle these +events appropriately. + +Previously applications had to manually check, upon receiving messages, +whether the message contained any SMP TLVs that are relevant to the +current SMP state. + +/* Handle and send the appropriate message(s) to the sender/recipient + * depending on the message events. All the events only require an opdata, + * the event, and the context. The message and err will be NULL except for + * some events (see below). The possible events are: + * - OTRL_MSGEVENT_ENCRYPTION_REQUIRED + * Our policy requires encryption but we are trying to send + * an unencrypted message out. + * - OTRL_MSGEVENT_ENCRYPTION_ERROR + * An error occured while encrypting a message and the message + * was not sent. + * - OTRL_MSGEVENT_CONNECTION_ENDED + * Message has not been sent because our buddy has ended the + * private conversation.

The argument 'smessage' will + * also be passed and it will contain the plaintext message. + * - OTRL_MSGEVENT_RCVDMSG_UNRECOGNIZED + * Cannot recognize the type of OTR message received. + * - OTRL_MSGEVENT_RCVDMSG_FOR_OTHER_INSTANCE + * Received and discarded a message intended for another instance. */ +void (*handle_msg_event)(void *opdata, OtrlMessageEvent msg_event, + ConnContext *context, const char *message, + gcry_error_t err); + +This operation is called when some type of exceptional event has occured +that your application may want to be aware of. Your application may want +to write an event to a log file, display a message to the user, or +ignore the event. While it is not required to implement this operation, +it is probably a good idea. + + +/* Create a instance tag for the given accountname/protocol if + * desired. */ +void (*create_instag)(void *opdata, const char *accountname, + const char *protocol); + +This is called when the library notices this account name and protocol +pair does not have an instance tag. Similar to create_privkey(), your +application may simply open a file handle and call: +gcry_error_t otrl_instag_generate_FILEp(OtrlUserState us, FILE *instf, + const char *accountname, const char *protocol) + +If you don't provide an implementation for this operation, a new +non-persistent instance tag will be randomly generated. One benefit to +having a persisted instance tag is that if your application closes and +re-opens during a private conversation, further messages you receive +from this buddy will correctly raise the +OTRL_MSGEVENT_RCVDMSG_UNREADABLE event instead of raising +OTRL_MSGEVENT_RCVDMSG_FOR_OTHER_INSTANCE because destination instance +tag is now different from your own. + + +/* Called immediately before a data message is encrypted, and after a data + * message is decrypted. The OtrlConvertType parameter has the value + * OTRL_CONVERT_SENDING or OTRL_CONVERT_RECEIVING to differentiate these + * cases. */ +void (*convert_msg)(void *opdata, ConnContext *context, + OtrlConvertType convert_type, char ** dest, const char *src); + +/* Deallocate a string returned by convert_msg. */ +void (*convert_free)(void *opdata, ConnContext *context, char *dest); + +The convert_msg() operation is called immediately before a message is +encrypted and immediately after a message is decrypted. This callback +can tweak the plaintext message as needed. One use case would be for an +application to tweak formatting on the plaintext if, for example, this +is something that would normally be done on the plaintext by some other +entity while the message is in transit. + +/* When timer_control is called, turn off any existing periodic + * timer. + * + * Additionally, if interval > 0, set a new periodic timer + * to go off every interval seconds. When that timer fires, you + * must call otrl_message_poll(userstate, uiops, uiopdata); from the + * main libotr thread. + * + * The timing does not have to be exact; this timer is used to + * provide forward secrecy by cleaning up stale private state that + * may otherwise stick around in memory. Note that the + * timer_control callback may be invoked from otrl_message_poll + * itself, possibly to indicate that interval == 0 (that is, that + * there's no more periodic work to be done at this time). + * + * If you set this callback to NULL, then you must ensure that your + * application calls otrl_message_poll(userstate, uiops, uiopdata); + * from the main libotr thread every definterval seconds (where + * definterval can be obtained by calling + * definterval = otrl_message_poll_get_default_interval(userstate); + * right after creating the userstate). The advantage of + * implementing the timer_control callback is that the timer can be + * turned on by libotr only when it's needed. + * + * It is not a problem (except for a minor performance hit) to call + * otrl_message_poll more often than requested, whether + * timer_control is implemented or not. + * + * If you fail to implement the timer_control callback, and also + * fail to periodically call otrl_message_poll, then you open your + * users to a possible forward secrecy violation: an attacker that + * compromises the user's computer may be able to decrypt a handful + * of long-past messages (the first messages of an OTR + * conversation). + */ +void (*timer_control)(void *opdata, unsigned int interval); + +In order to prevent a forward secrecy violation, applications using +libotr now need to be able to call otrl_message_poll on occasion. The +simplest thing to do is just to set up a local timer that calls that +function every definterval = +otrl_message_poll_get_default_interval(userstate) seconds. To avoid +unnecessary overhead, however, the timer_control callback is available. +If you set timer_control to non-NULL, it will be called with +instructions to turn on or off the periodic timer, and to what interval. + +You must also be sure to turn off the timer before freeing your +userstate with otrl_userstate_free. + +3.2. Instance Tags + +If your application allows the same user to be logged in multiple times +from different locations, it should probably be aware of instance tags. +A user can maintain multiple concurrent OTR conversations with a buddy +who is logged in multiple times. Only one of the buddy's sessions can be +a client who is running OTR protocol version 2. When a user has a +conversation with a buddy who is running OTR protocol version 2, the +conversation is associated with a ConnContext that lists +"their_instance" as OTRL_INSTAG_MASTER (which has a value of 0). Each +version 3 conversation with the same buddy will have its own +ConnContext, which you can differentiate by the value in the +"their_instance" field. + +In the linked list of ConnContexts, the master context for a buddy is +always listed immediately before its children. Fingerprints are only +stored with the master context. Given a ConnContext associated to a +conversation with a buddy, you can easily iterate over all the contexts +for that buddy by doing the following: + +void example_something_happened(ConnContext * context) { + ConnContext * context_iter = context->m_context; + + while (context_iter && context_iter->m_context == context->m_context) { + /* Something you wish to affect all contexts of a particular buddy */ + context_iter = context_iter->next; + } + +If a user has multiple OTR sessions with the same buddy, your +application will likely want to provide some way for the user to select +which instance to send outgoing messages to. You can detect when a user +has multiple OTR sessions with the same buddy by iterating over the +ConnContexts of a buddy when a conversation has gone secure and checking +whether more than one is not in plaintext state. You specify which +instance outgoing messages are directed to in otrl_message_sending: + +gcry_error_t otrl_message_sending(OtrlUserState us, + const OtrlMessageAppOps *ops, + void *opdata, const char *accountname, const char *protocol, + const char *recipient, otrl_instag_t instag, const char *original_msg, + OtrlTLV *tlvs, char **messagep, OtrlFragmentPolicy fragPolicy, + ConnContext **contextp, + void (*add_appdata)(void *data, ConnContext *context), + void *data); + +Instead of an actual instance tag, you can specify a meta instance tag +(e.g., if the user has not made an explicit selection). Here are the +list of meta instance tags, as defined in instag.h: + +#define OTRL_INSTAG_BEST 1 /* Most secure, based on: conv status, + * then fingerprint status, then most recent. */ +#define OTRL_INSTAG_RECENT 2 /* Most recent of the two meta instances below */ +#define OTRL_INSTAG_RECENT_RECEIVED 3 +#define OTRL_INSTAG_RECENT_SENT 4 + +OTRL_INSTAG_BEST choses the instance that has the best conv status, then +fingerprint status (in the event of a tie), then most recent (similarly +in the event of a tie). When calculating how recent an instance has been +active, OTRL_INSTAG_BEST is limited by a one second resolution. +OTRL_INSTAG_RECENT* does not have this limitation, but due to inherent +uncertainty in some networks, libotr's notion of the most recent may not +always agree with the remote network. It is important to understand +this limitation due to the issue noted in the next paragraph. + +Note that instances do add some uncertainty when dealing with networks +that only deliver messages to the most recently active session for a +buddy who is logged in multiple times. If you have a particular instance +selected, and the IM network is simply not going to deliver to that +particular instance, there isn't too much libotr can do. In this case, +you may want your application to warn when a user has selected an +instance that is not the most recent. + +To explicitly specify the destination instance of a protocol version 2 +conversation with a particular buddy, the instag value is +OTRL_INSTAG_MASTER. + +To look up a ConnContext associated with a particular instance (or meta- +instance), specify the instance in otrl_context_find(): + +ConnContext * otrl_context_find(OtrlUserState us, const char *user, + const char *accountname, const char *protocol, + otrl_instag_t their_instance, int add_if_missing, int *addedp, + void (*add_app_data)(void *data, ConnContext *context), void *data) + +If your application persists instance tags, when it starts up, it should +call one the following functions to read the persisted instance tags: + +gcry_error_t otrl_instag_read(OtrlUserState us, const char *filename); +gcry_error_t otrl_instag_read_FILEp(OtrlUserState us, FILE *instf); + +It would make sense to do this immediately after your application has +read stored privkeys and fingerprints. + +3.3. Fragmentation Changes + +In libotr version 3.2.0, you would need to call otrl_message_sending() +to create an encrypted message, and then call fragment_and_send() to +get libotr to fragment and inject that message. In libotr 4.0.0, the +functionality of fragment_and_send() has been integrated into +otrl_message_sending(). Simply specify an OtrlFragmentPolicy to +otrl_message_sending(). The fragmentation policies are the same as +before, and an addition policy "OTRL_FRAGMENT_SEND_SKIP" has been added +for cases when fragmentation is not desired. + +3.4. Asynchronous Private Key Generation + +An application that wants to begin asynchronous key generation calls the +following method: + +/* Begin a private key generation that will potentially take place in + * a background thread. This routine must be called from the main + * thread. It will set *newkeyp, which you can pass to + * otrl_privkey_generate_calculate in a background thread. If it + * returns gcry_error(GPG_ERR_EEXIST), then a privkey creation for + * this accountname/protocol is already in progress, and *newkeyp will + * be set to NULL. */ +gcry_error_t otrl_privkey_generate_start(OtrlUserState us, + const char *accountname, const char *protocol, void **newkeyp) + +A background thread can call the following method with the structure +that was passed into "newkeyp" above: + +/* Do the private key generation calculation. You may call this from a + * background thread. When it completes, call + * otrl_privkey_generate_finish from the _main_ thread. */ +gcry_error_t otrl_privkey_generate_calculate(void *newkey) + + +Upon completion the application would call: + +/* Call this from the main thread only. It will write the newly created + * private key into the given file and store it in the OtrlUserState. */ +gcry_error_t otrl_privkey_generate_finish(OtrlUserState us, + void *newkey, const char *filename) + +If the privkey generation was cancelled, the application should call: + +/* Call this from the main thread only, in the event that the background + * thread generating the key is cancelled. The newkey is deallocated, + * and must not be used further. */ +void otrl_privkey_generate_cancelled(OtrlUserState us, void *newkey) + + +3.5. Library Initialization + +If you currently initialize libotr with the recommended OTRL_INIT; +macro, you do not need to change anything. + +If you call otrl_init(ver_major, ver_minor, ver_sub) directly, then know +that this function no longer returns void. Previously, if the +application requested version numbers incompatible with those of the +library, the library would exit(1). Now, the otrl_init call will return +a non-zero error code. You must check the return value of otrl_init (a +gcry_error_t), and if it is non-zero, your application's expected +API/ABI does not match the installed libotr, and libotr cannot be used. + diff --git a/libotr/libotr-4.1.1/aclocal.m4 b/libotr/libotr-4.1.1/aclocal.m4 new file mode 100644 index 0000000..c39029a --- /dev/null +++ b/libotr/libotr-4.1.1/aclocal.m4 @@ -0,0 +1,1307 @@ +# generated automatically by aclocal 1.14.1 -*- Autoconf -*- + +# Copyright (C) 1996-2013 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, +[m4_warning([this file was generated for autoconf 2.69. +You have another version of autoconf.

However, + \fIduring\fP a conversation, your correspondent is assured the messages + he sees are authentic and unmodified. + - Perfect forward secrecy + - If you lose control of your private keys, no previous conversation + is compromised. +.PP +The OTR Toolkit is useful for analyzing and/or +forging OTR messages. Why do we offer this? Primarily, to make +absolutely sure that transcripts of OTR conversations are really easy +to forge after the fact. [Note that \fIduring\fP an OTR conversation, +messages can't be forged without real-time access to the secret keys on +the participants' computers, and in that case, all security has already +been lost.] Easily-forgeable transcripts help us provide the +"Deniability" property: if someone claims you said something over OTR, +they'll have no proof, as anyone at all can modify a transcript to make +it say whatever they like, and still have all the verification come out +correctly. + +Here are the six programs in the toolkit: + + - otr_parse + - Parse OTR messages given on stdin, showing the values of all the + fields in OTR protocol messages. + + - otr_sesskeys our_privkey their_pubkey + - Shows our public key, the session id, two AES and two MAC keys + derived from the given Diffie-Hellman keys (one private, one public). + + - otr_mackey aes_enc_key + - Shows the MAC key derived from the given AES key. + + - otr_readforge aes_enc_key [newmsg] + - Decrypts an OTR Data message using the given AES key, and displays + the message. + - If newmsg is given, replace the message with that one, encrypt + and MAC it properly, and output the resulting OTR Data Message. + This works even if the given key was not correct for the original + message, so as to enable complete forgeries. + + - otr_modify mackey old_text new_text offset + - Even if you can't read the data because you don't know either + the AES key or the Diffie-Hellman private key, but you can make a + good guess that the substring "old_text" appears at the given + offset in the message, replace the old_text with the new_text + (which must be of the same length), recalculate the MAC with the + given mackey, and output the resulting Data message. + - Note that, even if you don't know any text in an existing message, + you can still forge messages of your choice using the + otr_readforge command, above. + + - otr_remac mackey sender_instance receiver_instance flags snd_keyid rcv_keyid pubkey counter encdata revealed_mackeys + - Make a new OTR protocol version 3 Data Message, with the given + pieces (note that the data part is already encrypted).
