Examples

Asymmetric keypair generation:

./gost2012 -keygen 

Digital signature (ECDSA):

./gost2012 -sign -key $prvkey < file.ext > sign.txt
sign=$(cat sign.txt)
./gost2012 -verify -key $pubkey -signature $sign < file.ext

Asymmetric Encryption:

./gost2012 -enc -key $pubkey < file.ext > file.enc
./gost2012 -dec -key $prvkey < file.enc

Shared key agreement (ECDH a.k.a. VKO):

./gost2012 -derive -key $prvkey -pub $pubkey
