Question

OpenSSL

How to sign a file in OpenSSL with a private key of an electronic signature in the GOST R 34.10 format issued by an authorized certification authority (the task is complicated by the fact that certification authorities do not use free software, an EDS certificate is issued in the format of Crypto-Pro, Crypto-ARM, VipNET and its Do I need to somehow convert to OpenSSL format)? How to use the same OpenSSL to perform the opposite action - to verify the authenticity of an electronic signature using a public root certificate of a certification authority?
