A reference implementation of the Russian GOST crypto algorithms for OpenSSL.

This engine provides an implementation of various Russian cryptographic algorithms, known generally as GOST cryptographic algorithms (see detailed list below). These algorithms can be used both via OpenSSL command line tools and via high-level libopenssl calls.

OpenSSL GOST Engine also includes 'gostsum' and 'gost12sum' command line tools for generating and checking GOST R34.11-94 and GOST R34.11-2012 hashsums. They have the same purposes and behavior as the well-known sha1sum and md5sum utilities. These utilities can be used independently from OpenSSL.
