Ruby library implementing GOST 34.10-12 ECC (not production ready)

Add this line to your application’s Gemfile:

gem 'crypto_gost'

And then execute:

$ bundle

Or install it yourself as:

$ gem install crypto_gost

group = CryptoGost::Group::Nistp192
private_key = group.generate_private_key
public_key = group.generate_public_key private_key
message = 'ruby'

signature = CryptoGost::Create.new(message, group).(private_key) #=> #<CryptoGost::Signature:0x007fbf1a128e38 @r=797072555870978995277638382002810748614228757069663574432, @s=3005972168119503640451023541340174801109033211348956501476>

# signature = CryptoGost::Create.new(message, group).call(private_key)

CryptoGost::Verify.new(message, group).(public_key, signature) # => true

# CryptoGost::Verify.new(message, group).call(public_key, signature)
