The final version of the utility has been released cryproarmpkcs. The principal difference from previous versions is the addition of functions related to the creation of self-signed certificates. Certificates can be created both with key pair generation and by previously created certificate requests (PKCS#10). The generated certificate, together with the generated key pair, is placed in a secure PKCS#12 container. The PKCS#12 container can be used when working with openssl supporting GOST R 34.10-2012.
The utility is absolutely self-sufficient and works on Linux, Windows, OS X platforms.
