engine

A reference implementation of the Russian GOST crypto algorithms for OpenSSL

Compatibility: OpenSSL 3.0

License: same as the corresponding version of OpenSSL.

Mailing list: http://www.wagner.pp.ru/list-archives/openssl-gost/

Some useful links: https://www.altlinux.org/OSS-GOST-Crypto

DO NOT TRY BUILDING MASTER BRANCH AGAINST openssl 1.1.1! Use 1_1_1 branch instead!

provider

A reference implementation in the same spirit as the engine, specified above.

This is currently work in progress, with only a subset of all intended functionality implemented: symmetric ciphers, hashes and MACs.
