Libakrypt is a free and open source library (crypto module) distributed under the MIT License. This library written in C11 and provides some interfaces for key management, data encryption, integrity checking, signing messages and verifying of digital signatures. The main goal of Libakrypt is implementation a lot of Russian crypto mechanisms, decribed by national standards and methodological recomendations in accordance with R 1323565.1.012-2017 "Basic principles of creating and modernization for crypto modules".

We have implementation of:

1. GOST R 34.12-2015 block ciphers "Magma" & "Kuznechik" with 64 bit and 128 bit block sizes respectively;
2. GOST R 34.13-2015 modes for block ciphers;
3. New russian AEAD mode (MGM, Multilinear Galois mode) for authenticated encryption;
4. GOST R 34.11-2012 hash functions from Streebog family;
5. Montgomery arithmetic for prime fileds;
6. Group operations on elliptic curves in short Weierstrass form;
7. GOST R 34.10-2012 digital signature algorithms for elliptic curves described by R 50.1.114-2016;
8. R 50.1.113-2016 crypto algorithms such as HMAC;
9. National variant of password-based key derivation function (PBKDF2) described by R 50.1.111-2016;
10. A some set of pseudo random generators for various operation systems including R 1323565.1.006-2017 mechanism.

Library can be used successfully under Linux, Windows (since XP), FreeBSD and MacOs operation systems. Also we have positive runs on mobile devices under Sailfish OS.

The library can be compiled with many compilers, such as gcc, clang, Microsoft Visual C, TinyCC and icc. You can get the last version of source codes from github.com

git clone https://github.com/axelkenzo/libakrypt-0.x

The build system for libakrypt is cmake.

On Unix platforms you can compile & build library with following commands

mkdir build
cd build
cmake ../libakrypt-0.x
make

If you want to compile and build a set of test programs you may run

cmake -DLIBAKRYPT_INTERNAL_TESTS=ON ../libakrypt-0.x
make test

On Windows you need to install phtreads library. After this you can run a Microsoft Visual 20XX Console and execute a following sequence

mkdir build
cd build
cmake.exe -G "NMake Makefiles" ../libakrypt-0.x
nmake.exe

The full list of compile & build options and full documentation you can find in doc directory or libakrypt-doc-0.x.pdf (in russian).

Since this version still under development we don't recomended to use it in real security applications.
