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.

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 Lesser 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.

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.

Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey 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; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If 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 convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU 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 that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - 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. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -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. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - 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 -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - 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 3 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, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program 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, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

It is not interoperable with earlier versions of - Nettle. Thanks to Nikos Mavrogiannopoulos. To easily - differentiate at compile time, sha3.h defines the constant - NETTLE_SHA3_FIPS202. - - * Fix corner-case carry propagation bugs affecting elliptic - curve operations on the curves secp_256r1 and secp_384r1 on - certain platforms, including x86_64. Reported by Hanno Böck. - - New features: - - * New functions for RSA private key operations, identified by - the "_tr" suffix, with better resistance to side channel - attacks and to hardware or software failures which could - break the CRT optimization. See the Nettle manual for - details. Initial patch by Nikos Mavrogiannopoulos. - - * New functions nettle_version_major, nettle_version_minor, as - a run-time variant of the compile-time constants - NETTLE_VERSION_MAJOR and NETTLE_VERSION_MINOR. - - Optimizations: - - * New ARM Neon implementation of the chacha stream cipher. - - Miscellaneous: - - * ABI detection on mips, with improved default libdir - location. Contributed by Klaus Ziegler. - - * Fixes for ARM assembly syntax, to work better with the clang - assembler. Thanks to Jukka Ukkonen. - - * Disabled use of ifunc relocations for fat builds, to fix - problems most easily triggered by using dlopen RTLD_NOW. - - The shared library names are libnettle.so.6.2 and - libhogweed.so.4.2, with sonames still libnettle.so.6 and - libhogweed.so.4. It is intended to be fully binary compatible - with nettle-3.1. - -NEWS for the Nettle 3.1.1 release - - This release fixes a couple of non-critical bugs. - - Bug fixes: - - * By accident, nettle-3.1 disabled the assembly code for the - secp_224r1 and secp_521r1 elliptic curves on all x86_64 - configurations, making signature operations on those curves - 10%-30% slower. This code is now re-enabled. - - * The x86_64 assembly implementation of gcm hashing has been - fixed to work with the Sun/Oracle assembler. - - The shared library names are libnettle.so.6.1 and - libhogweed.so.4.1, with sonames still libnettle.so.6 and - libhogweed.so.4. It is intended to be fully binary compatible - with nettle-3.1. - -NEWS for the Nettle 3.1 release - - This release adds a couple of new features. - - The library is mostly source-level compatible with nettle-3.0. - It is however not binary compatible, due to the introduction - of versioned symbols, and extensions to the base64 context - structs. The shared library names are libnettle.so.6.0 and - libhogweed.so.4.0, with sonames libnettle.so.6 and - libhogweed.so.4. - - Bug fixes: - - * Fixed a missing include of , which made the - camellia implementation fail on all 64-bit non-x86 - platforms. - - * Eliminate out-of-bounds reads in the C implementation of - memxor (related to valgrind's --partial-loads-ok flag). - - Interface changes: - - * Declarations of many internal functions are moved from ecc.h - to ecc-internal.h. The functions are undocumented, and - luckily they're apparently also unused by applications, so I - don't expect any problems from this change. - - New features: - - * Support for curve25519 and for EdDSA25519 signatures. - - * Support for "fat builds" on x86_64 and arm, where the - implementation of certain functions is selected at run-time - depending on available cpu features. Configure with - --enable-fat to try this out. If it turns out to work well - enough, it will likely be enabled by default in later - releases. - - * Support for building the hogweed library (public key - support) using "mini-gmp", a small but slower implementation - of a subset of the GMP interfaces. Note that builds using - mini-gmp are *not* binary compatible with regular builds, - and more likely to leak side-channel information. - - One intended use-case is for small embedded applications - which need to verify digital signatures. - - * The shared libraries are now built with versioned symbols. - Should reduce problems in case a program links explicitly to - nettle and/or hogweed, and to gnutls, and the program and - gnutls expect different versions. - - * Support for "URL-safe" base64 encoding and decoding, as - specified in RFC 4648. Contributed by Amos Jeffries. - - Optimizations: - - * New x86_64 implementation of AES, using the "aesni" - instructions. Autodetected in fat builds. In non-fat builds, - it has to be enabled explicitly with --enable-x86-aesni. - - Build system: - - * Use the same object files for both static and shared - libraries. This eliminates the *.po object files which were - confusing to some tools (as well as humans). Like before, - PIC code is used by default; to build a non-pic static - library, configure with --disable-pic --disable-shared. - - Miscellaneous: - - * Made type-checking hack in CBC_ENCRYPT and similar macros - stricter, to generate warnings if they are used with - functions which have a length argument smaller than size_t. - -NEWS for the Nettle 3.0 release - - This is a major release, including several interface changes, - and new features, some of which are a bit experimental. - Feedback is highly appreciated. - - It is *not* binary (ABI) compatible with earlier versions. It - is mostly source-level (API) compatible, with a couple of - incompatibilities noted below. The shared library names are - libnettle.so.5.0 and libhogweed.so.3.0, with sonames - libnettle.so.5 and libhogweed.so.3. - - There may be some problems in the new interfaces and new - features which really need incompatible fixes. It is likely - that there will be an update in the form of a 3.1 release in - the not too distant future, with small but incompatible - changes, and if that happens, bugfix-only releases 3.0.x are - unlikely. Users and applications which desire better API and - ABI stability are advised to stay with nettle-2.7.x (latest - version is now 2.7.1) until the dust settles. - - Interface changes: - - * For the many _set_key functions, it is now consider the - normal case to have a fixed key size, with no key_size - arguments. _set_key functions with a length parameter are - provided only for algorithms with a truly variable keysize, - and where it makes sense for backwards compatibility. - - INCOMPATIBLE CHANGE: cast128_set_key no longer accepts a key - size argument. The old function is available under a new - name, cast5_set_key. - - INCOMPATIBLE CHANGE: The function typedef - nettle_set_key_func no longer accepts a key size argument. - In particular, this affects users of struct nettle_cipher. - - * The nettle_cipher abstraction (in nettle-meta.h) is - restricted to block ciphers only. The encrypt and decrypt - functions now take a const argument for the context. - - INCOMPATIBLE CHANGE: nettle_arcfour, i.e., the nettle_cipher - abstraction for the arcfour stream cipher, is deleted. - - INCOMPATIBLE CHANGE: New type, nettle_cipher_func, for the - encrypt and decrypt fields of struct nettle_cipher. - - * New DSA interface, with a separate struct dsa_param to - represent the underlying group, and generalized dsa_sign and - dsa_verify functions which don't care about the hash - function used. Limited backwards compatibility provided in - dsa-compat.h. - - INCOMPATIBLE CHANGE: Declarations of the old interface, - e.g., struct dsa_public_key, dsa_sha1_sign, etc, is moved to - dsa-compat.h. - - INCOMPATIBLE CHANGE: The various key conversion functions, - e.g., dsa_keypair_to_sexp, all use the new DSA interface, with - no backwards compatible functions. - - INCOMPATIBLE CHANGE: dsa_generate_keypair also uses the new - interface. dsa-compat.h declares a function - dsa_compat_generate_keypair, implementing the old - interface, and #defines dsa_generate_keypair to refer to - this backwards compatible function. - - * New AES and Camellia interfaces. There are now separate - context structs for each key size, e.g., aes128_ctx and - camellia256_ctx, and corresponding new functions. The old - interface, with struct aes_ctx and struct camellia_ctx, is - kept for backwards compatibility, but might be removed in - later versions. - - * The type of most length arguments is changed from unsigned - to size_t. The memxor functions have their pointer arguments - changed from uint8_t * to void *, for consistency with - related libc functions. - - * For hash functions, the constants *_DATA_SIZE have been - renamed to *_BLOCK_SIZE. Old names kept for backwards - compatibility. - - Removed features: - - * The nettle_next_prime function has been deleted. - Applications should use GMP's mpz_nextprime instead. - - * Deleted the RSAREF compatibility, including the header file - rsa-compat.h and everything declared therein. - - * Also under consideration for removal is des-compat.h and - everything declared therein. This implements a subset of the - old libdes/ssleay/openssl interface for DES and triple-DES, - and it is poorly tested. If anyone uses this interface, - please speak up! Otherwise, it will likely be removed in the - next release. - - Bug fixes: - - * Building with ./configure --disable-static now works. - - * Use GMP's allocation functions for temporary storage related - to bignums, to avoid potentially large stack allocations. - - * Fixes for shared libraries on M$ Windows. - - New features: - - * Support for Poly1305-AES MAC. - - * Support for the ChaCha stream cipher and EXPERIMENTAL - support for the ChaCha-Poly1305 AEAD mode. Specifications - are still in flux, and future releases may do incompatible - changes to track standardization. Currently uses 256-bit key - and 64-bit nonce. - - * Support for EAX mode. - - * Support for CCM mode. Contributed by Owen Kirby. - - * Additional variants of SHA512 with output size of 224 and - 256 bits. Contributed by Joachim Strömbergson. - - * New interface, struct nettle_aead, for mechanisms providing - authenticated encryption with associated data (AEAD). - - * DSA: Support a wider range for the size of q and a wider - range for the digest size. - - Optimizations: - - * New x86_64 assembly for GCM and MD5. Modest speedups on the - order of 10%-20%. - - Miscellaneous: - - * SHA3 is now documented as EXPERIMENTAL. Nettle currently - implements SHA3 as specified at the time Keccak won the SHA3 - competition. However, the final standard specified by NIST - is likely to be incompatible, in which case future releases - may do incompatible changes to track standardization. - - * The portability fix for the rotation macros, mentioned in - NEWS for 2.7.1, actually didn't make it into that release. - It is included now. - - * cast128_set_key rewritten for clarity, also eliminating a - couple of compiler warnings. - - * New command line tool nettle-pbkdf2. - NEWS for the 2.7.1 release - This is a bugfix release. + This is a bugfix release. - Bug fixes: + Bug fixes: - * Fixed a bug in the new ECC code.

Nettle is a cryptographic library that is designed to fit easily in more @@ -325,195 +237,146 @@ kernel space. In most contexts, you need more than the basic cryptographic algorithms, you also need some way to keep track of available algorithms, their properties and variants. You often have some algorithm selection process, often dictated by a protocol you want to implement. -

And as the requirements of applications differ in subtle and not so subtle ways, an API that fits one application well can be a pain to use in a different context. And that is why there are so many different cryptographic libraries around. -

The idea is that one can build several application and context specific interfaces on top of Nettle, and share the code, test cases, benchmarks, documentation, etc. Examples are the Nettle module for the Pike language, and LSH, which both use an object-oriented abstraction on top of the library. -

A cryptographic hash function is a function that takes variable size strings, and maps them to strings of fixed, short, length. There are naturally lots of collisions, as there are more possible 1MB files than 20 byte strings. But the function is constructed such that is hard to find the collisions. More precisely, a cryptographic hash function H should have the following properties: -

The standard is a result of a competition, where +the winner, also known as Keccak, was designed by Guido Bertoni, Joan Daemen, Michaël Peeters and Gilles Van Assche. It is structurally very different from all widely used earlier hash functions. Like SHA2, there are several variants, with output sizes of 224, 256, 384 and 512 bits -(28, 32, 48 and 64 octets, respectively). In August 2015, it was -formally standardized by NIST, as FIPS 202, -http://dx.doi.org/10.6028/NIST.FIPS.202. -

-

Note that the SHA3 implementation in earlier versions of Nettle was -based on the specification at the time Keccak was announced as the -winner of the competition, which is incompatible with the final standard -and hence with current versions of Nettle. The nette/sha3.h -defines a preprocessor symbol NETTLE_SHA3_FIPS202 to indicate -conformance with the standard. -

+There are two main classes of ciphers: Block ciphers and stream ciphers. + +

A block cipher can process data only in fixed size chunks, called +blocks. Typical block sizes are 8 or 16 octets. To encrypt arbitrary messages, you usually have to pad it to an integral number of blocks, split it into blocks, and then process each block. The simplest way is to process one block at a time, independent of each other.

A stream cipher can be used for messages of arbitrary length. A typical stream cipher is a keyed pseudo-random generator. To encrypt a plaintext message of n octets, you key the generator, generate n octets of pseudo-random data, and XOR it with the plaintext. To decrypt, regenerate the same stream using the key, XOR it to the ciphertext, and the plaintext is recovered. -

A common misconception is that encryption, by itself, implies authentication. Say that you and a friend share a secret key, and you receive an encrypted message. You apply the key, and get a plaintext message that makes sense to you. Can you then be sure that it really was -your friend that wrote the message you’re reading? The answer is no. For +your friend that wrote the message you're reading? The answer is no. For example, if you were using a block cipher in ECB mode, an attacker may pick up the message on its way, and reorder, delete or repeat some of -the blocks. Even if the attacker can’t decrypt the message, he can +the blocks. Even if the attacker can't decrypt the message, he can change it so that you are not reading the same message as your friend wrote. If you are using a block cipher in CBC mode rather than ECB, or are using a stream cipher, the possibilities for this sort of attack are different, but the attacker can still make predictable changes to the message. -

Some ciphers have so called “weak keys”, keys that results in undesirable structure after the key setup processing, and should be avoided. In Nettle, most key setup functions have no return value, but for ciphers with weak keys, the return value indicates whether or not the given key is weak. For good keys, key setup returns 1, and for weak keys, it returns 0. When possible, avoid algorithms that -have weak keys. There are several good ciphers that don’t have any weak +have weak keys.

6.2.1 AES

AES is a block cipher, specified by NIST as a replacement for the older DES standard. The standard is the result of a competition between cipher designers. The winning design, also known as RIJNDAEL, was constructed by Joan Daemen and Vincent Rijnmen. -

Like all the AES candidates, the winning design uses a block size of 128 -bits, or 16 octets, and three possible key-size, 128, 192 and 256 bits -(16, 24 and 32 octets) being the allowed key sizes. It does not have any -weak keys. Nettle defines AES in <nettle/aes.h>, and there is one -context struct for each key size. (Earlier versions of Nettle used a -single context struct, struct aes_ctx, for all key sizes. This -interface kept for backwards compatibility). -

6.2.2 ARCFOUR

+

ARCFOUR is a stream cipher, also known under the trade marked name RC4, and it is one of the fastest ciphers around. A problem is that the key setup of ARCFOUR is quite weak, you should never use keys with structure, keys that are ordinary passwords, or sequences of keys like -“secret:1”, “secret:2”, .... If you have keys that don’t look +“secret:1”, “secret:2”, .... If you have keys that don't look like random bit strings, and you want to use ARCFOUR, always hash the key before feeding it to ARCFOUR. Furthermore, the initial bytes of the generated key stream leak information about the key; for this reason, it is recommended to discard the first 512 bytes of the key stream. -

The +and Telephone Corporation, described in RFC3713, and recommended +by some Japanese and European authorities as an alternative to AES. The algorithm is patented. The implementation in Nettle is derived from the implementation released by NTT under the GNU LGPL (v2.1 or later), and relies on the implicit patent license of the LGPL. There is also a statement of royalty-free licensing for Camellia at http://www.ntt.co.jp/news/news01e/0104/010417.html, but this statement has some limitations which seem problematic for free software. -

6.2.9 DES3

The inadequate key size of DES has already been mentioned. One way to increase the key size is to pipe together several DES boxes with independent keys. It turns out that using two DES ciphers is not as secure as one might think, even if the key size of the combination is a respectable 112 bits. -

The standard way to increase DES's key size is to use three DES boxes. The mode of operation is a little peculiar: the middle DES box is wired in the reverse direction. To encrypt a block with DES3, you encrypt it using the first 56 bits of the key, then decrypt it using the middle 56 bits of the key, and finally encrypt it again using the last 56 bits of the key. This is known as “ede” triple-DES, for “encrypt-decrypt-encrypt”. -

6.3 Cipher modes

Cipher modes of operation specifies the procedure to use when encrypting -a message that is larger than the cipher’s block size. As explained in +a message that is larger than the cipher's block size. As explained in See Cipher functions, splitting the message into blocks and processing them independently with the block cipher (Electronic Code -Book mode, ECB), leaks information. -

-

Besides ECB, Nettle provides a two other modes of operation: -Cipher Block Chaining (CBC), Counter mode (CTR), and -a couple of AEAD modes (see Authenticated encryption). -CBC is widely used, but there are a few subtle issues of -information leakage, see, e.g., -SSH CBC -vulnerability. Today, CTR is usually preferred over CBC. -

-

Modes like CBC and CTR provide no message -authentication, and should always be used together with a MAC -(see Keyed hash functions) or signature to authenticate the message. -

+When using CBC mode, plaintext blocks are not encrypted independently of each other, like in Electronic Cook Book mode. Instead, when encrypting a block in CBC mode, the previous ciphertext -block is XORed with the plaintext before it is fed to the block cipher. -When encrypting the first block, a random block called an IV, or +block is XORed with the plaintext before it is fed to the block cipher. +When encrypting the first block, a random block called an IV, or Initialization Vector, is used as the “previous ciphertext block”. The IV should be chosen randomly, but it need not be kept secret, and can even be transmitted in the clear together with the encrypted data. -

6.4 Authenticated encryption with associated data

- - - -

Since there are some subtle design choices to be made when combining a -block cipher mode with out authentication with a MAC. In -recent years, several constructions that combine encryption and -authentication have been defined. These constructions typically also -have an additional input, the “associated data”, which is -authenticated but not included with the message. A simple example is an -implicit message number which is available at both sender and receiver, -and which needs authentication in order to detect deletions or replay of -messages. This family of building blocks are therefore called -AEAD, Authenticated encryption with associated data. -

-

The aim is to provide building blocks that it is easier for designers of -protocols and applications to use correctly. There is also some -potential for improved performance, if encryption and authentication can -be done in a single step, although that potential is not realized for -the constructions currently supported by Nettle. -

-

For encryption, the inputs are: -

-
    -
  • The key, which can be used for many messages. -
  • A nonce, which must be unique for each message using the same key. -
  • Additional associated data to be authenticated, but not included in the -message. -
  • The cleartext message to be encrypted. -
- -

The outputs are: -

-
    -
  • The ciphertext, of the same size as the cleartext. -
  • A digest or “authentication tag”. -
- -

Decryption works the same, but with cleartext and ciphertext -interchanged. All currently supported AEAD algorithms always -use the encryption function of the underlying block cipher, for both -encryption and decryption. -

-

Usually, the authentication tag should be appended at the end of the -ciphertext, producing an encrypted message which is slightly longer than -the cleartext. However, Nettle’s low level AEAD functions -produce the authentication tag as a separate output for both encryption -and decryption. -

-

Both associated data and the message data (cleartext or ciphertext) can -be processed incrementally. In general, all associated data must be -processed before the message data, and all calls but the last one must -use a length that is a multiple of the block size, although some -AEAD may implement more liberal conventions. The CCM -mode is a bit special in that it requires the message lengths up front, -other AEAD constructions don’t have this restriction. -

-

The supported AEAD constructions are Galois/Counter mode -(GCM), EAX, ChaCha-Poly1305, and Counter with -CBC-MAC (CCM). There are some weaknesses -in GCM authentication, see -http://csrc.nist.gov/groups/ST/toolkit/BCM/documents/comments/CWC-GCM/Ferguson2.pdf. -CCM and EAX use the same building blocks, but the -EAX design is cleaner and avoids a couple of inconveniences of -CCM. Therefore, EAX seems like a good conservative -choice. The more recent ChaCha-Poly1305 may also be an attractive but -more adventurous alternative, in particular if performance is important. -

6.4.1 EAX

- -

The EAX mode is an AEAD mode whichcombines -CTR mode encryption, See CTR, with a message authentication -based on CBC, See CBC. The implementation in Nettle is -restricted to ciphers with a block size of 128 bits (16 octets). -EAX was defined as a reaction to the CCM mode, -See CCM, which uses the same primitives but has some undesirable and -inelegant properties. -

-

EAX supports arbitrary nonce size; it’s even possible to use -an empty nonce in case only a single message is encrypted for each key. -

-

Nettle’s support for EAX consists of a low-level general -interface, some convenience macros, and specific functions for -EAX using AES-128 as the underlying cipher. These -interfaces are defined in <nettle/eax.h> -

- -

6.4.1.1 General EAX interface

-

-

Size of the EAX digest, also 16. -

- -
-
Function: void eax_set_key (struct eax_key *key, const void *cipher, nettle_cipher_func *f)
-

Initializes key. cipher gives a context struct for the -underlying cipher, which must have been previously initialized for -encryption, and f is the encryption function. -

- -
-
Function: void eax_set_nonce (struct eax_ctx *eax, const struct eax_key *key, const void *cipher, nettle_cipher_func *f, size_t nonce_length, const uint8_t *nonce)
-

Initializes ctx for processing a new message, using the given -nonce. -

- -
-
Function: void eax_update (struct eax_ctx *eax, const struct eax_key *key, const void *cipher, nettle_cipher_func *f, size_t data_length, const uint8_t *data)
-

Process associated data for authentication. All but the last call for -each message must use a length that is a multiple of the block -size. Unlike many other AEAD constructions, for EAX -it’s not necessary to complete the processing of all associated data -before encrypting or decrypting the message data. -

- -
-
Function: void eax_encrypt (struct eax_ctx *eax, const struct eax_key *key, const void *cipher, nettle_cipher_func *f, size_t length, uint8_t *dst, const uint8_t *src)
-
Function: void eax_decrypt (struct eax_ctx *eax, const struct eax_key *key, const void *cipher, nettle_cipher_func *f, size_t length, uint8_t *dst, const uint8_t *src)
-

Encrypts or decrypts the data of a message. cipher is the context -struct for the underlying cipher and f is the encryption function. -All but the last call for each message must use a length that is -a multiple of the block size. -

- -
-
Function: void eax_digest (struct eax_ctx *eax, const struct eax_key *key, const void *cipher, nettle_cipher_func *f, size_t length, uint8_t *digest);
-

Extracts the message digest (also known “authentication tag”). This is -the final operation when processing a message. If length is -smaller than EAX_DIGEST_SIZE, only the first length octets -of the digest are written. -

+

When a message is encrypted using a sequence of calls to +ctr_crypt, all but the last call must use a length that is +a multiple of the block size. +

+
+
+ +
+— Macro: CTR_SET_COUNTER (ctx, iv)
+

First argument is a pointer to a context struct as defined by +CTR_CTX, and the second is a pointer to an initial counter that +is copied into that context. +

- -

6.4.1.2 EAX helper macros

+
+— Macro: CTR_CRYPT (ctx, f, length, dst, src)
+

A simpler way to invoke ctr_crypt. The first argument is a +pointer to a context struct as defined by CTR_CTX, and the second +argument is an encryption function following Nettle's conventions. The +last three arguments define the source and destination area for the +operation. +

-

The following macros are defined. -

-
-
Macro: EAX_CTX (context_type)
-

This defines an all-in-one context struct, including the context of the -underlying cipher and all EAX state. It expands -to -

-
{
-   struct eax_key key;
-   struct eax_ctx eax;
-   context_type cipher;
-}

6.4.3 Counter with CBC-MAC mode

- - - - -

CCM mode is a combination of counter mode with message -authentication based on cipher block chaining, the same building blocks -as EAX, see EAX. It is constructed on top of a block cipher -which must have a block size of 128 bits. CCM mode is -recommended by NIST in -NIST Special Publication 800-38C. Nettle’s support for CCM consists of -a low-level general interface, a message encryption and authentication -interface, and specific functions for CCM using AES as the underlying -block cipher. These interfaces are defined in <nettle/ccm.h>. -

-

In CCM, the length of the message must be known before -processing. The maximum message size depends on the size of the nonce, -since the message size is encoded in a field which must fit in a single -block, together with the nonce and a flag byte. E.g., with a nonce size -of 12 octets, there are three octets left for encoding the message -length, the maximum message length is 2^24 - 1 octets. -

-

CCM mode encryption operates as follows: -

    -
  • The nonce and message length are concatenated to create -B_0 = flags | nonce | mlength - -
  • The authenticated data and plaintext is formatted into the string -B = L(adata) | adata | padding | plaintext | padding with -padding being the shortest string of zero bytes such that the -length of the string is a multiple of the block size, and -L(adata) is an encoding of the length of adata. - -
  • The string B is separated into blocks B_1 ... -B_n -
  • The authentication tag T is calculated as -T=0, for i=0 to n, do T = E_k(B_i XOR T) - -
  • An initial counter is then initialized from the nonce to create -IC = flags | nonce | padding, where padding is the -shortest string of zero bytes such that IC is exactly one block -in length. - -
  • The authentication tag is encrypted using using CTR mode: -MAC = E_k(IC) XOR T - -
  • The plaintext is then encrypted using CTR mode with an -initial counter of IC+1. -
- -

CCM mode decryption operates similarly, except that the -ciphertext and MAC are first decrypted using CTR mode to -retreive the plaintext and authentication tag. The authentication tag -can then be recalucated from the authenticated data and plantext, and -compared to the value in the message to check for authenticity. -

- -

6.4.3.1 General CCM interface

- -

For all of the functions in the CCM interface, cipher is -the context struct for the underlying cipher and f is the -encryption function. The cipher’s encryption key must be set before -calling any of the CCM functions. The cipher’s decryption -function and key are never used. -

- -

To encrypt a message using the general CCM interface, set the -message nonce and length using ccm_set_nonce and then call -ccm_update to generate the digest of any authenticated data. -After all of the authenticated data has been digested use -ccm_encrypt to encrypt the plaintext. Finally, use -ccm_digest to return the encrypted MAC. -

-

To decrypt a message, use ccm_set_nonce and ccm_update the -same as you would for encryption, and then call ccm_decrypt to -decrypt the ciphertext. After decrypting the ciphertext -ccm_digest will return the encrypted MAC which should -be identical to the MAC in the received message. -

6.4.3.2 CCM message interface

- -

The CCM message fuctions provides a simple interface that will -perform authentication and message encryption in a single function call. -The length of the cleartext is given by mlength and the length of -the ciphertext is given by clength, always exactly tlength -bytes longer than the corresponding plaintext. The length argument -passed to a function is always the size for the result, clength -for the encryption functions, and mlength for the decryption -functions. -

-

Decrypts the ciphertext from src, outputs the plaintext to -dst, recalculates the MAC from adata and the -plaintext, and compares it to the final tlength bytes of -src. If the values of the received and calculated MACs -are equal, this will return 1 indicating a valid and authenticated -message. Otherwise, this function will return zero. -

6.4.4 ChaCha-Poly1305

- -

ChaCha-Poly1305 is a combination of the ChaCha stream cipher and the -poly1305 message authentication code (see Poly1305). It originates -from the NaCl cryptographic library by D. J. Bernstein et al, which -defines a similar construction but with Salsa20 instead of ChaCha. -

-

Nettle’s implementation ChaCha-Poly1305 should be considered -experimental. At the time of this writing, there is no -authoritative specification for ChaCha-Poly1305, and a couple of -different incompatible variants. Nettle implements it using the original -definition of ChaCha, with 64 bits (8 octets) each for the nonce and the -block counter. Some protocols prefer to use nonces of 12 bytes, and it’s -a small change to ChaCha to use the upper 32 bits of the block counter -as a nonce, instead limiting message size to 2^32 blocks or 256 -GBytes, but that variant is currently not supported. -

-

For ChaCha-Poly1305, the ChaCha cipher is initialized with a key, of 256 -bits, and a per-message nonce. The first block of the key stream -(counter all zero) is set aside for the authentication subkeys. Of this -64-octet block, the first 16 octets specify the poly1305 evaluation -point, and the next 16 bytes specify the value to add in for the final -digest. The final 32 bytes of this block are unused. Note that unlike -poly1305-aes, the evaluation point depends on the nonce. This is -preferable, because it leaks less information in case the attacker for -some reason is lucky enough to forge a valid authentication tag, and -observe (from the receiver’s behaviour) that the forgery succeeded. -

-

The ChaCha key stream, starting with counter value 1, is then used to -encrypt the message. For authentication, poly1305 is applied to the -concatenation of the associated data, the cryptotext, and the lengths of -the associated data and the message, each a 64-bit number (eight octets, -little-endian). Nettle defines ChaCha-Poly1305 in -<nettle/chacha-poly1305.h>. -

+A keyed hash function, or Message Authentication Code (MAC) is a function that takes a key and a message, and produces fixed size MAC. It should be hard to compute a message and a matching MAC without knowledge of the key. It should also be hard to compute the key given only messages and corresponding MACs. -

Keyed hash functions are useful primarily for message authentication, when Alice and Bob shares a secret: The sender, Alice, computes the MAC and attaches it to the message. The receiver, Bob, also computes the MAC of the message, using the same key, and compares that -to Alice’s value. If they match, Bob can be assured that +to Alice's value. If they match, Bob can be assured that the message has not been modified on its way from Alice. -

-

However, unlike digital signatures, this assurance is not transferable. -Bob can’t show the message and the MAC to a third party and + +

However, unlike digital signatures, this assurance is not transferable. +Bob can't show the message and the MAC to a third party and prove that Alice sent that message. Not even if he gives away the key to the third party. The reason is that the same key is used on both sides, and anyone knowing the key can create a correct MAC for any message. If Bob believes that only he and Alice knows the key, and -he knows that he didn’t attach a MAC to a particular message, -he knows it must be Alice who did it. However, the third party can’t +he knows that he didn't attach a MAC to a particular message, +he knows it must be Alice who did it.

+One can build keyed hash functions from ordinary hash functions. Older constructions simply concatenate secret key and message and hashes that, but such constructions have weaknesses. A better construction is HMAC, described in RFC 2104. -

For an underlying hash function H, with digest size l and internal block size b, HMAC-H is constructed as follows: From a given key k, two distinct subkeys k_i and k_o are constructed, both of length b. The HMAC-H of a message m is then computed as H(k_o | H(k_i | m)), where | denotes string concatenation. -

HMAC keys can be of any length, but it is recommended to use keys of length l, the digest size of the underlying hash function H. Keys that are longer than b are shortened to length -l by hashing with H, so arbitrarily long keys aren’t -very useful. -

This auto-increment uses network byte order and it takes the length of the -nonce into account. E.g., if the initial nonce is “abc” (3 octets), +nonce into acount. E.g., if the initial nonce is “abc” (3 octets), this value is zero-padded to 16 octets for the first message. For the next message, the nonce is incremented to “abd”, and this incremented value is zero-padded to 16 octets. -

So it is important to use the right variant. For consistency with other -hash and MAC functions, Nettle’s _digest functions for +hash and MAC functions, Nettle's _digest functions for UMAC accept a length parameter so that the output can be truncated to any desired size, but it is recommended to stick to the specified output size and select the umac variant corresponding to the desired size. -

6.5.4 Poly1305

+_set_nonce function explicitly for each message. +

-

Poly1305-AES is a message authentication code designed by D. J. -Bernstein. It treats the message as a polynomial modulo the prime number -2^130 - 5. -

-

The key, 256 bits, consists of two parts, where the first half is an -AES-128 key, and the second half specifies the point where the -polynomial is evaluated. Of the latter half, 22 bits are set to zero, to -enable high-performance implementation, leaving 106 bits for specifying -an evaluation point r. For each message, one must also provide a -128-bit nonce. The nonce is encrypted using the AES key, and -that’s the only thing AES is used for. -

-

The message is split into 128-bit chunks (with final chunk possibly -being shorter), each read as a little-endian integer. Each chunk has a -one-bit appended at the high end. The resulting integers are treated as -polynomial coefficients modulo 2^130 - 5, and the polynomial is -evaluated at the point r. Finally, this value is reduced modulo -2^128, and added (also modulo 2^128) to the encrypted -nonce, to produce an 128-bit authenticator for the message. See -http://cr.yp.to/mac/poly1305-20050329.pdf for further details. -

-

Clearly, variants using a different cipher than AES could be -defined. Another variant is the ChaCha-Poly1305 AEAD -construction (see ChaCha-Poly1305). Nettle defines -Poly1305-AES in nettle/poly1305.h. -

Nettle uses GMP, the GNU bignum library, for all calculations with large numbers. In order to use the public-key features of Nettle, you must install GMP, at least version 3.0, before compiling Nettle, and you need to link your programs with -lhogweed -lnettle -lgmp. -

The concept of Public-key encryption and digital signatures was discovered by Whitfield Diffie and Martin E. Hellman and described in a paper 1976.

And if there are many users or entities that need to communicate, each pair needs a shared secret key known by nobody else. -

6.6.1 RSA

The RSA algorithm was the first practical digital signature algorithm that was constructed. It was described 1978 in a paper by Ronald Rivest, Adi Shamir and L.M. Adleman, and the technique was also patented in the USA in 1983. The patent expired on September 20, 2000, and since that day, RSA can be used freely, even in the USA. -

Let's first look at how RSA key-pairs are generated. First n is chosen as the product of two large prime numbers p -and q of roughly the same size (so if n is 2000 bits, -p and q are about 1000 bits each). One also computes the +and q of roughly the same size (so if n is 1000 bits, +p and q are about 500 bits each). One also computes the number phi = (p-1)(q-1), in mathematical speak, phi is the order of the multiplicative group of integers modulo n. -

Next, e is chosen.

Finally, a number d, d < n is computed such that e d mod phi = 1. It can be shown that such a number exists (this is why e and phi must have no common factors), and that for all x, -

So d is the trapdoor, if we know d and y = F(x), we can recover x as y^d mod n. d is also the private half of the RSA key-pair. -

The most common signature operation for RSA is defined in PKCS#1, a specification by RSA Laboratories. The message to be -signed is first hashed using a cryptographic hash function, e.g. +signed is first hashed using a cryptographic hash function, e.g. MD5 or SHA1. Next, some padding, the ASN.1 “Algorithm Identifier” for the hash function, and the message digest itself, are concatenated and converted to a number x. The signature is computed from x and the private key as s = x^d -mod n1. The signature, s is a +mod n1. The signature, s is a number of about the same size of n, and it usually encoded as a sequence of octets, most significant octet first. -

The verification operation is straight-forward, x is computed from the message in the same way as above. Then s^e mod n is computed, the operation returns true if and only if the result equals x. -

-

The RSA algorithm can also be used for encryption. RSA encryption uses -the public key (n,e) to compute the ciphertext m^e mod n. -The PKCS#1 padding scheme will use at least 8 random and non-zero -octets, using m of the form [00 02 padding 00 plaintext]. -It is required that m < n, and therefor the plaintext must be -smaller than the octet size of the modulo n, with some margin. -

-

To decrypt the message, one needs the private key to compute m = -c^e mod n followed by checking and removing the padding. -

-

random_ctx and random is a randomness generator. -random(random_ctx, length, dst) should generate length -random octets and store them at dst. For advice, see -See Randomness. -

-

progress and progress_ctx can be used to get callbacks -during the key generation process, in order to uphold an illusion of -progress. progress can be NULL, in that case there are no -callbacks. -

p_bits and q_bits are the desired sizes of p and -q. To generate keys that conform to the original DSA -standard, you must use q_bits = 160 and select p_bits of -the form p_bits = 512 + l*64, for 0 <= l <= 8, where the -smaller sizes are no longer recommended, so you should most likely stick -to p_bits = 1024.

6.6.5 Elliptic curves

For cryptographic purposes, an elliptic curve is a mathematical group of points, and computing logarithms in this group is computationally difficult problem.

If P and Q are two points, and k is an +integer, the point sum, P + Q, and the multiple k P can be +computed efficiently, but given only two points P and Q, +finding an integer k such that Q = k P is the elliptic curve discrete logarithm problem. -

6.7.3.3 Curve25519

- -

Curve25519 is an elliptic curve of Montgomery type, y^2 = x^3 + -486662 x^2 + x (mod p), with p = 2^255 - 19. Montgomery curves -have the advantage of simple and efficient point addition based on the -x-coordinate only. This particular curve was proposed by D.~J.~Bernstein -in 2006, for fast Diffie-Hellman key exchange. The group generator is -defined by x = 9 (there are actually two points with x = -9, differing by the sign of the y-coordinate, but that doesn’t matter -for the curve25519 operations which work with the x-coordinate only). -

-

The curve25519 functions are defined as operations on octet strings, -which are interpreted as x-coordinates in little-endian byte order. -

-

Of all the possible input strings, only about half correspond to points -on curve25519, i.e., a value that can be produced by -curve25519_mul_g. The other half corresponds to points on a -related “twist curve”. The current implementation of -curve25519_mul uses a Montgomery ladder for the scalar -multiplication, as suggested in the curve25519 literature, and produces -a well defined output for all possible inputs, no matter if points are -on the proper curve or on its twist. However, at the time of writing, it -is not yet ruled out that other implementations could be faster, and -therefore the behaviour for inputs corresponding to points on the twist -curve must be considered an implementation idiosyncrasy, and may change -in future versions. -

-
-
Constant: CURVE25519_SIZE

The size of the strings representing curve25519 points and scalars, 32. -

- -
-
Function: void curve25519_mul_g (uint8_t *q, const uint8_t *n)
-

Computes Q = N G, where G is the group generator and -N is an integer. The input argument n and the output -argument q use a little-endian representation of the scalar and -the x-coordinate, respectively. They are both of size -CURVE25519_SIZE. -

-

This function is intended to be compatible with the function -crypto_scalar_mult_base in the NaCl library. -

-

The output value is defined only when the input p is a string -produced by curve25519_mul_g. (See discussion above, about the -twist curve). -

This function is intended to be compatible with the function -crypto_scalar_mult in the NaCl library. -

6.7.3.4 EdDSA

- - -

EdDSA is a signature scheme proposed by D.~J.~Bernstein et al. in 2011. -It is defined using a “Twisted Edwards curve”, of the form -x^2 -+ y^2 = 1 + d x^2 y^2. The specific signature scheme Ed25519 uses a -curve which is equivalent to curve25519: The two groups used differ only -by a simple change of coordinates, so that the discrete logarithm -problem is of equal difficulty in both groups. -

-

Unlike other signature schemes in Nettle, the input to the EdDSA sign -and verify functions is the possibly large message itself, not a hash -digest. EdDSA is a variant of Schnorr signatures, where the message is -hashed together with other data during the signature process, providing -resilience to hash-collisions: A successful attack finding collisions in -the hash function does not automatically translate into an attack to -forge signatures. EdDSA also avoids the use of a randomness source by -generating the needed signature nonce from a hash of the private key and -the message, which means that the message is actually hashed twice when -creating a signature. If signing huge messages, it is possible to hash -the message first and pass the short message digest as input to the sign -and verify functions, however, the resilience to hash collision is then -lost. -

+— Function: int base64_decode_single (struct base64_decode_ctx *ctx, uint8_t *dst, uint8_t src)
+

Decodes a single byte (src) and stores the result in dst. +Returns amount of output (0 or 1), or -1 on errors. +

+ +
+— Macro: BASE64_DECODE_LENGTH (length)
+

+ +
+— Function: void base64_decode_update (struct base64_decode_ctx *ctx, unsigned *dst_length, uint8_t *dst, unsigned src_length, const uint8_t *src)
+

After ctx is initialized, this function may be called to decode src_length +bytes from src. dst should point to an area of size at least +BASE64_DECODE_LENGTH(length), and for sanity checking, dst_length +should be initialized to the size of that area before the call. +dst_length is updated to the amount of decoded output.

8 Installation

-

Nettle uses autoconf. To build it, unpack the source and run -

-
-
./configure
-make
-make check
-make install
-
- -

to install it under the default prefix, /usr/local. Using GNU -make is strongly recommended. By default, both static and shared -libraries are built and installed. -

-

To get a list of configure options, use ./configure --help. Some -of the more interesting are: -

-
-
--enable-fat
-

Include multiple versions of certain functions in the library, and -select the ones to use at run-time, depending on available processor -features. Supported for ARM and x86_64. -

-
-
--enable-mini-gmp
-

Use the smaller and slower “mini-gmp” implementation of the bignum -functions needed for public-key cryptography, instead of the real GNU -GMP library. This option is intended primarily for smaller embedded -systems. Note that builds using mini-gmp are not binary compatible -with regular builds of Nettle, and more likely to leak side-channel -information. -

-
-
--disable-shared
-

Omit building the shared libraries. -

-
-
--disable-dependency-tracking
-

Disable the automatic dependency tracking. You will likely need this -option to be able to build with BSD make. -

This family of -building blocks are therefore called AEAD, Authenticated encryption with -associated data. - - The aim is to provide building blocks that it is easier for designers -of protocols and applications to use correctly. There is also some -potential for improved performance, if encryption and authentication can -be done in a single step, although that potential is not realized for -the constructions currently supported by Nettle. - - For encryption, the inputs are: - - • The key, which can be used for many messages. - • A nonce, which must be unique for each message using the same key. - • Additional associated data to be authenticated, but not included in - the message. - • The cleartext message to be encrypted. - - The outputs are: - - • The ciphertext, of the same size as the cleartext. - • A digest or “authentication tag”. - - Decryption works the same, but with cleartext and ciphertext -interchanged. All currently supported AEAD algorithms always use the -encryption function of the underlying block cipher, for both encryption -and decryption. - - Usually, the authentication tag should be appended at the end of the -ciphertext, producing an encrypted message which is slightly longer than -the cleartext. However, Nettle’s low level AEAD functions produce the -authentication tag as a separate output for both encryption and -decryption. - - Both associated data and the message data (cleartext or ciphertext) -can be processed incrementally. In general, all associated data must be -processed before the message data, and all calls but the last one must -use a length that is a multiple of the block size, although some AEAD -may implement more liberal conventions. The CCM mode is a bit special -in that it requires the message lengths up front, other AEAD -constructions don’t have this restriction. - - The supported AEAD constructions are Galois/Counter mode (GCM), EAX, -ChaCha-Poly1305, and Counter with CBC-MAC (CCM). There are some -weaknesses in GCM authentication, see -. -CCM and EAX use the same building blocks, but the EAX design is cleaner -and avoids a couple of inconveniences of CCM. Therefore, EAX seems like -a good conservative choice.

E.g., with a nonce size of 12 -octets, there are three octets left for encoding the message length, the -maximum message length is 2^24 - 1 octets. - - CCM mode encryption operates as follows: - • The nonce and message length are concatenated to create ‘B_0 = - flags | nonce | mlength’ - - • The authenticated data and plaintext is formatted into the string - ‘B = L(adata) | adata | padding | plaintext | padding’ with - ‘padding’ being the shortest string of zero bytes such that the - length of the string is a multiple of the block size, and - ‘L(adata)’ is an encoding of the length of ‘adata’. - - • The string ‘B’ is separated into blocks ‘B_1’ ... ‘B_n’ - • The authentication tag ‘T’ is calculated as ‘T=0, for i=0 to n, do - T = E_k(B_i XOR T)’ - - • An initial counter is then initialized from the nonce to create ‘IC - = flags | nonce | padding’, where ‘padding’ is the shortest string - of zero bytes such that ‘IC’ is exactly one block in length. - - • The authentication tag is encrypted using using CTR mode: ‘MAC = - E_k(IC) XOR T’ - - • The plaintext is then encrypted using CTR mode with an initial - counter of ‘IC+1’. - - CCM mode decryption operates similarly, except that the ciphertext -and MAC are first decrypted using CTR mode to retreive the plaintext and -authentication tag. The authentication tag can then be recalucated from -the authenticated data and plantext, and compared to the value in the -message to check for authenticity. - -6.4.3.1 General CCM interface -............................. - -For all of the functions in the CCM interface, CIPHER is the context -struct for the underlying cipher and F is the encryption function. The -cipher’s encryption key must be set before calling any of the CCM -functions. The cipher’s decryption function and key are never used. - - -- Context struct: struct ccm_ctx - Holds state corresponding to a particular message. - - -- Constant: CCM_BLOCK_SIZE - CCM’s block size, 16. - - -- Constant: CCM_DIGEST_SIZE - Size of the CCM digest, 16. - -- Constant: CCM_MIN_NONCE_SIZE - -- Constant: CCM_MAX_NONCE_SIZE - The the minimum and maximum sizes for an CCM nonce, 7 and 14, - respectively. - - -- Macro: CCM_MAX_MSG_SIZE (NONCE_SIZE) - The largest allowed plaintext length, when using CCM with a nonce - of the given size. - - -- Function: void ccm_set_nonce (struct ccm_ctx *CTX, const void - *CIPHER, nettle_cipher_func *F, size_t NONCELEN, const uint8_t - *NONCE, size_t AUTHLEN, size_t MSGLEN, size_t TAGLEN) - Initializes CTX using the given nonce and the sizes of the - authenticated data, message, and MAC to be processed. - - -- Function: void ccm_update (struct ccm_ctx *CTX, const void *CIPHER, - nettle_cipher_func *F, size_t LENGTH, const uint8_t *DATA) - Provides associated data to be authenticated. Must be called after - ‘ccm_set_nonce’, and before ‘ccm_encrypt’, ‘ccm_decrypt’, or - ‘ccm_digest’. - - -- Function: void ccm_encrypt (struct ccm_ctx *CTX, const void *CIPHER, - nettle_cipher_func *F, size_t LENGTH, uint8_t *DST, const - uint8_t *SRC) - -- Function: void ccm_decrypt (struct ccm_ctx *CTX, const void *CIPHER, - nettle_cipher_func *F, size_t LENGTH, uint8_t *DST, const - uint8_t *SRC) - Encrypts or decrypts the message data. Must be called after - ‘ccm_set_nonce’ and before ‘ccm_digest’. All but the last call for - each message _must_ use a length that is a multiple of the block - size. - - -- Function: void ccm_digest (struct ccm_ctx *CTX, const void *CIPHER, - nettle_cipher_func *F, size_t LENGTH, uint8_t *DIGEST) - Extracts the message digest (also known “authentication tag”). - This is the final operation when processing a message. LENGTH is - usually equal to the TAGLEN parameter supplied to ‘ccm_set_nonce’, - but if you provide a smaller value, only the first LENGTH octets of - the digest are written. - - To encrypt a message using the general CCM interface, set the message -nonce and length using ‘ccm_set_nonce’ and then call ‘ccm_update’ to -generate the digest of any authenticated data. After all of the -authenticated data has been digested use ‘ccm_encrypt’ to encrypt the -plaintext. Finally, use ‘ccm_digest’ to return the encrypted MAC. - - To decrypt a message, use ‘ccm_set_nonce’ and ‘ccm_update’ the same -as you would for encryption, and then call ‘ccm_decrypt’ to decrypt the -ciphertext. After decrypting the ciphertext ‘ccm_digest’ will return -the encrypted MAC which should be identical to the MAC in the received -message. - -6.4.3.2 CCM message interface -............................. - -The CCM message fuctions provides a simple interface that will perform -authentication and message encryption in a single function call. The -length of the cleartext is given by MLENGTH and the length of the -ciphertext is given by CLENGTH, always exactly TLENGTH bytes longer than -the corresponding plaintext. The length argument passed to a function -is always the size for the result, CLENGTH for the encryption functions, -and MLENGTH for the decryption functions. - - -- Function: void ccm_encrypt_message (void *CIPHER, nettle_cipher_func - *F, size_t NLENGTH, const uint8_t *NONCE, size_t ALENGTH, - const uint8_t *ADATA, size_t TLENGTH, size_t CLENGTH, uint8_t - *DST, const uint8_t *SRC) - Computes the message digest from the ADATA and SRC parameters, - encrypts the plaintext from SRC, appends the encrypted MAC to - ciphertext and outputs it to DST. - - -- Function: int ccm_decrypt_message (void *CIPHER, nettle_cipher_func - *F, size_t NLENGTH, const uint8_t *NONCE, size_t ALENGTH, - const uint8_t *ADATA, size_t TLENGTH, size_t MLENGTH, uint8_t - *DST, const uint8_t *SRC) - Decrypts the ciphertext from SRC, outputs the plaintext to DST, - recalculates the MAC from ADATA and the plaintext, and compares it - to the final TLENGTH bytes of SRC. If the values of the received - and calculated MACs are equal, this will return 1 indicating a - valid and authenticated message. Otherwise, this function will - return zero. - -6.4.3.3 CCM-AES interface -......................... - -The AES CCM functions provide an API for using CCM mode with the AES -block ciphers. The parameters all have the same meaning as the general -and message interfaces, except that the CIPHER, F, and CTX parameters -are replaced with an AES context structure, and a set-key function must -be called before using any of the other functions in this interface. - - -- Context struct: struct ccm_aes128_ctx - Holds state corresponding to a particular message encrypted using - the AES-128 block cipher. - - -- Context struct: struct ccm_aes192_ctx - Holds state corresponding to a particular message encrypted using - the AES-192 block cipher. - - -- Context struct: struct ccm_aes256_ctx - Holds state corresponding to a particular message encrypted using - the AES-256 block cipher. - - -- Function: void ccm_aes128_set_key (struct ccm_aes128_ctx *CTX, const - uint8_t *KEY) - -- Function: void ccm_aes192_set_key (struct ccm_aes192_ctx *CTX, const - uint8_t *KEY) - -- Function: void ccm_aes256_set_key (struct ccm_aes256_ctx *CTX, const - uint8_t *KEY) - Initializes the encryption key for the AES block cipher.

It originates -from the NaCl cryptographic library by D. J. Bernstein et al, which -defines a similar construction but with Salsa20 instead of ChaCha. - - Nettle’s implementation ChaCha-Poly1305 should be considered -*experimental*. At the time of this writing, there is no authoritative -specification for ChaCha-Poly1305, and a couple of different -incompatible variants. Nettle implements it using the original -definition of ChaCha, with 64 bits (8 octets) each for the nonce and the -block counter. Some protocols prefer to use nonces of 12 bytes, and -it’s a small change to ChaCha to use the upper 32 bits of the block -counter as a nonce, instead limiting message size to 2^32 blocks or 256 -GBytes, but that variant is currently not supported. - - For ChaCha-Poly1305, the ChaCha cipher is initialized with a key, of -256 bits, and a per-message nonce. The first block of the key stream -(counter all zero) is set aside for the authentication subkeys. Of this -64-octet block, the first 16 octets specify the poly1305 evaluation -point, and the next 16 bytes specify the value to add in for the final -digest. The final 32 bytes of this block are unused. Note that unlike -poly1305-aes, the evaluation point depends on the nonce. This is -preferable, because it leaks less information in case the attacker for -some reason is lucky enough to forge a valid authentication tag, and -observe (from the receiver’s behaviour) that the forgery succeeded. - - The ChaCha key stream, starting with counter value 1, is then used to -encrypt the message. For authentication, poly1305 is applied to the -concatenation of the associated data, the cryptotext, and the lengths of -the associated data and the message, each a 64-bit number (eight octets, -little-endian).

It should be hard to compute a message and a matching MAC without -knowledge of the key. It should also be hard to compute the key given +knowledge of the key. It should also be hard to compute the key given only messages and corresponding MACs. Keyed hash functions are useful primarily for message authentication, when Alice and Bob shares a secret: The sender, Alice, computes the MAC -and attaches it to the message. The receiver, Bob, also computes the -MAC of the message, using the same key, and compares that to Alice’s -value. If they match, Bob can be assured that the message has not been +and attaches it to the message. The receiver, Bob, also computes the +MAC of the message, using the same key, and compares that to Alice's +value. If they match, Bob can be assured that the message has not been modified on its way from Alice. However, unlike digital signatures, this assurance is not -transferable. Bob can’t show the message and the MAC to a third party -and prove that Alice sent that message. Not even if he gives away the -key to the third party. The reason is that the _same_ key is used on +transferable. Bob can't show the message and the MAC to a third party +and prove that Alice sent that message. Not even if he gives away the +key to the third party. The reason is that the _same_ key is used on both sides, and anyone knowing the key can create a correct MAC for any -message. If Bob believes that only he and Alice knows the key, and he -knows that he didn’t attach a MAC to a particular message, he knows it -must be Alice who did it. However, the third party can’t distinguish +message. If Bob believes that only he and Alice knows the key, and he +knows that he didn't attach a MAC to a particular message, he knows it +must be Alice who did it.

Note that builds using mini-gmp are *not* binary - compatible with regular builds of Nettle, and more likely to leak - side-channel information. - -‘--disable-shared’ - Omit building the shared libraries. - -‘--disable-dependency-tracking’ - Disable the automatic dependency tracking. You will likely need - this option to be able to build with BSD make. + Using GNU make is recommended. For other make programs, in particular +BSD make, you may have to use the `--disable-dependency-tracking' +option to `./configure'.
