JsonJws
JsonJws is a Ruby gem that provides support for JWS (JSON Web Signature) with JSON serialization, specifically designed to handle multiple signatures.
Installation
Add this line to your application's Gemfile:
gem 'json_jws'And then execute:
$ bundle install
Or install it yourself as:
$ gem install json_jws
Usage
require "jose"
require "openssl"
require 'json_jws'
# If you want to load key from private key string
# rsa_key_01 = OpenSSL::PKey::RSA.new(rsa_priv_01_str)
# rsa_key_02 = OpenSSL::PKey::RSA.new(rsa_priv_01_str)
rsa_key_01 = OpenSSL::PKey::RSA.generate(2048)
puts "RSA key 01 Private: ", rsa_key_01.to_s, "\n"
puts "RSA key 01 Public: ", rsa_key_01.public_key.to_s
puts "\n" * 3
rsa_key_02 = OpenSSL::PKey::RSA.generate(2048)
puts "RSA key 02 Private: ", rsa_key_02.to_s, "\n"
puts "RSA key 02 Public: ", rsa_key_02.public_key.to_s
puts "\n" * 3
header = { "alg" => "RS256" }
payload = "It’s a dangerous business, Frodo, going out your door.".encode("utf-8")
payload = "{1}".encode("utf-8")
jwk = JOSE::JWK.from_key(rsa_key_01)
jwk2 = JOSE::JWK.from_key(rsa_key_02)
puts "\n\nEncoding:\n"
json_jws = JSON_JWS.encode(jwk, header, payload)
puts "json_jws: \n", json_jws
puts "\n\nVerify json jws"
verify_result = JSON_JWS.verify(json_jws, [jwk])
print "verify_result: ", verify_result
puts "\n\nAdd another signature"
json_jws_2 = JSON_JWS.add_signature(json_jws, jwk2, { "alg" => "RS256", "extra" => "field" })
# json_jws_2 = JSON_JWS.add_signature(json_jws, jwk2, header)
puts "json_jws_2: \n", json_jws_2
puts "\n\nVerify json jws 2"
verify_result = JSON_JWS.verify(json_jws_2, [jwk, jwk2])
print "verify_result: ", verify_result
puts "\n\nJWS multiple signatures decoding"
decoded = JSON_JWS.decode(json_jws_2)
print "decoded: ", decodedDevelopment
After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install.
