Version 0.4.1 released

Changelog

• Issues #7 and #8 were fixed (kudos to @alexanius and @SamsonovAnton)
• Minor code improvements were made
• CI script was updated (we migrated to Trusty dist with preinstalled modern CMake)

Version 0.4 released

Changelog

• All functions were renamed to Gost15–specific.
• CTest was integrated instead of self-made selftests, and all implementations are now tested on each iteration.
• Implementation selection was rephrased via -DIMPLEMENTATION CMake option, check out README.
• Compiler-specific stuff was removed from CMake configuration.
• All inclusions of headers with integers types and qualifiers were moved to libgost15/platform.h header.

Compability issues

• Building library requires compiler supporting C99 standard.
• CMake does not generate buildable Microsoft Visual Studio solutions because MSVC does not support C99 restrict feature.
  I am working on this issue, it is to be fixed in future releases.

Roadmap

• Fix missing restrict type qualifier in Microsoft environment.
• Add seamless support for GOST R 34.13 (2015) modes of operation.

Version 0.3.6 released

Changes log

This release includes

• three versions of block encryption, decryption and key scheduling implementations: compact, optimised and SIMD,
• by-the-book integrated selftests,
• standalone benchmarking utility based on chrono.

Benchmarks and support for CMake build configuration

What's new?

Version 0.3.5 brings these new features:

• support for CMake build management,
• support for hardclock cycle-couting benchmark,
• support for building selftests and benchmarks out-of-the-box with GCC and Clang compilers.

Draft implementation of block encryption, decryption and key scheduling routines

This version of release includes three implementations versions:

• compact (at compact.c),
• optimised (at optimised.c),
• SIMD (at SIMD.c)

of basic cipher primitives:

• block encryption (encryptBlock),
• block decryption (decryptBlock),
• key scheduling.

Note that encryption and decryption modes in optimised and SIMD versions of implementation require different sets of round keys, the respective set is generated by functions:

• scheduleEncryptionRoundKeys,
• scheduleDecryptionRoundKeys.

All implementation versions are mutually exclusive, and only one version is compiled at a time.
