+certificates in the certs directory, otherwise default certstore test

+non-HMAC MAC in the openssl core, so GOST MAC is only option.

+OpenSSL 1.0 includes GOST engine by default. For OpenSSL 1.1 and above
+GOST engine is developed as separate project and can be downloaded from

+Debian buster and above includes gost engine as
