You can start by reading: https://github.com/openssl/openssl/blob/master/engines/ccgost/README.gost It has examples on how to generate GOST certificates. After that I would suggest running a test SSL/TLS connection with those certificates and openssl s_client and openssl s_server utilities. If it works, you may then recompile OpenSSL and make it dump all ...
I'd suggest to get OpenSSL source, build it, and run it under debugger, watching exactly what "-text" is doing to private key. One could verify exponentiation operations with a calculator having big numbers capability. ASN.1/DER parser could be handy to see private key file.
Cipher Feedback mode turns the block cipher (AES) into a self-synchronizing stream cipher which feeds back the full ciphertext block as the next IV. If you encrypt something smaller than a multiple of the block size, it will not use all of the block cipher output to create the ciphertext, just the amount it needs. Therefore there is not a padding ...
