Getting an error when trying to sign message

[gasparyanyur]

On my ubuntu 20 machine I have already installed and configured CryptoPro. So now I am trying to sign message using number571/go-cryptopro but getting the following error:

E[-2146893792][CreateContainer: CryptGenKey]
panic: error code: -3

goroutine 1 [running]:
github.com/number571/go-cryptopro/gost_r_34_10_2012.GenPrivKey(0xc000048cb0, 0x4b99e0, 0xc0000ac401)
        /root/go/pkg/mod/github.com/number571/[email protected]/gost_r_34_10_2012/gost.go:92 +0x25a

        /root/go/pkg/mod/github.com/number571/[email protected]/gost_r_34_10_2012/gost.go:18 +0x69
exit status 2

Here is the code

cfg := gkeys.NewConfig(gkeys.K256, "mkk", "password")

	priv, err := gkeys.NewPrivKey(cfg)
	if err != nil {
		fmt.Println(err)
		return
	}

	msg := []byte("hello, world!")
	sign, err := priv.Sign(msg)
	if err != nil {
		fmt.Println(err)
		return
	}

        fmt.Println(msg)
