Bitauth

BitAuth is a way to do secure, passwordless authentication proposed by Bitpay using the same elliptic-curve cryptography as Bitcoin

Add this line to your application's Gemfile:

gem 'bitauth'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bitauth

To Generate a new Key pair you can just instantiate a new BitAuth instance with no parameters:

require 'bitauth'

bitauth = BitAuth.new

bitauth.sin
bitauth.public_key
bitauth.private_key

To sign a message after that you can just call sign:

bitauth = BitAuth.new private_key: "HEX_PRIVATE_KEY"

signature = bitauth.sign("data")

You can then verify the message using just the public key:

bitauth = BitAuth.new public_key: "HEX_PUBLIC_KEY"

bitauth.verify("data", "signature")

require 'bitauth'

bitauth = BitAuth.new

data = '{"id":10, "message": "Demo Text"}'
signature = bitauth.sign(data)

if bitauth.verify(data, signature)
  puts "Everything checks out"
end
