GostCryptography

.NET driver for ViPNet CSP and CryptoPro CSP.
Implements crypto algorithms based on Russian national cryptographic standards GOST 28147-89, GOST R 34.12,
GOST R 34.10 and GOST R 34.11. Also provides abstractions to sign and verify CMS/PKCS #7 messages, sign,
verify and encrypt XML documents.
