R. Yushaev	5efebb7b48	Cleanup VeraCrypt related code ... Remove unnecessary constant variables by hardcoring values instead of looking up. Precalculate swaps that are known at compile time. Hardcode hashes_shown offset as zero for all TC / VC kernels.	6 years ago
R. Yushaev	47bd838e25	Add VeraCrypt Streebog support ... VeraCrypt added the possibility to use Streebog-512 as hashing algorithm for the key derivation. This commit adds the necessary VeraCrypt kernels as well as additional HMAC-Streebog kernels. - Add hash-mode 13771: VeraCrypt PBKDF2-HMAC-Streebog-512 + XTS 512 bit - Add hash-mode 13772: VeraCrypt PBKDF2-HMAC-Streebog-512 + XTS 1024 bit - Add hash-mode 13773: VeraCrypt PBKDF2-HMAC-Streebog-512 + XTS 1536 bit - Add hash-mode 11750: HMAC-Streebog-256 (key = $pass), big-endian - Add hash-mode 11760: HMAC-Streebog-256 (key = $salt), big-endian - Add hash-mode 11860: HMAC-Streebog-512 (key = $salt), big-endian - Add test suite for hash-modes 11750, 11760 and 11860 - Improve pure Streebog kernels	6 years ago
R. Yushaev	a8eb611b1c	Add HMAC-Streebog-512 (pure kernels) ... Implement HMAC based on GOST 34.11-2012 Streebog-512 as well as a test case for it. Both the PyGOST + hmac python module and the VeraCrypt HMAC for Streebog-512 were used as references. The kernels expect the digests to be in big-endian order according to the RFC examples for Streebog. Fix two bugs from commit 224315dd62. - Add hash-mode 11850: HMAC-Streebog-512 (key = $pass), big-endian - Add test case for hash-mode 11850 - Bugfix for a3-pure Streebog kernels (modes 11700 and 11800) - Rename a few Streebog constants in interface.h	6 years ago
R. Yushaev	224315dd62	Add pure kernels and tests for Streebog hashes ... Complete Streebog support with pure kernels that allow for passwords longer than 64 characters. Provide generic inc_hash_streebog files for future Streebog-based hash modes (HMAC, PBKDF2, VeraCrypt). Include streebog support in the test suite. For this, python module PyGOST is needed. Also add clarification to hash mode description stating that Streebog hashes are expected in big-endian byte order. There are several implementations, including PyGOST, which default to little-endian byte order, while the RFC examples are big-endian. - Add pure kernels for hash-mode 11700 (Streebog-256) - Add pure kernels for hash-mode 11800 (Streebog-512) - Tests: Add hash-modes 11700 (Streebog-256) and 11800 (Streebog-512)	6 years ago
