Are there alternatives to CryptoPro?

Question

Cryptography

Actually, the need is this (everything in a batch, non-interactive mode):

..it is necessary to request an array of random data, sign it with the UKEP and send it back for verification.

Well, to the heap:

only supports connections secured with TLS/HTTPS algorithms:
ssl_protocols: TLSv1
ssl_ciphers: GOST2012-GOST8912-GOST8912

Actually, as I understand it, I have one way - to CryptoPro, I just wanted to clarify, maybe there are some alternatives?
Well, for clarity: will only CryptoPro CSP be enough or what other licenses will you need to purchase from them?

Answer 1

CryptoPro CSP itself is just a crypto provider. It enables other tools to use GOST cryptography.
For the web, you also need to install the cryptopro browser plug-in, which seems to be free.
If you need to encrypt files on the command line, then you need to use the appropriate utility (cryptcp) - for Windows it is provided for a separate fee.
For use by users, you can use CryptoARM - a graphical interface for third-party crypto operations.
Or you can use CryptoPro CSP in your application - you can use CryptoAPI to work with CryptoPro CSP.

Answer 2

CryptoPro has an alternative, and even free and even with the FSB certificate, ViPNet CSP 4.2. But, as rightly noted above, despite the declared free competition, CryptoPro is actually a monopolist in state IS. I tested a bunch of ViPNet CSP 4.2 + ViPNet CryptoFile as a free replacement for CryptoPro 4 + CryptoARM, EPs were released in two different CAs, according to GOST-2001 and GOST-2012, but the CAs used Crypto Pro software and I didn’t succeed.
