Provides OpenSSL::SignatureAlgorithm::ECDSA, OpenSSL::SignatureAlgorithm::RSAPSS
and OpenSSL::SignatureAlgorithm::RSAPKCS1 ruby object wrapers on top of OpenSSL::PKey::EC
and OpenSSL::PKey::RSA, so that you can reason in terms of signature algorithms when
signing and/or verifying signatures, instead of keys.
Add this line to your application's Gemfile:
gem 'openssl-signature_algorithm'And then execute:
$ bundle install
Or install it yourself as:
$ gem install openssl-signature_algorithm
to_be_signed = "to-be-signed"
# Signer
algorithm = OpenSSL::SignatureAlgorithm::ECDSA.new("256")
signing_key = algorithm.generate_signing_key
signature = algorithm.sign(to_be_signed)
# Signer sends verify key to Verifier
verify_key_string = signing_key.verify_key.serialize
# Verifier
verify_key = OpenSSL::SignatureAlgorithm::ECDSA::VerifyKey.deserialize(verify_key_string)
algorithm = OpenSSL::SignatureAlgorithm::ECDSA.new("256")
algorithm.verify_key = verify_key
algorithm.verify(signature, to_be_signed)to_be_signed = "to-be-signed"
# Signer
algorithm = OpenSSL::SignatureAlgorithm::RSAPSS.new("256")
signing_key = algorithm.generate_signing_key
signature = algorithm.sign(to_be_signed)
# Signer sends verify key to Verifier
verify_key_string = signing_key.verify_key.serialize
# Verifier
verify_key = OpenSSL::SignatureAlgorithm::RSAPSS::VerifyKey.deserialize(verify_key_string)
algorithm = OpenSSL::SignatureAlgorithm::RSAPSS.new("256")
algorithm.verify_key = verify_key
algorithm.verify(signature, to_be_signed)to_be_signed = "to-be-signed"
# Signer
algorithm = OpenSSL::SignatureAlgorithm::RSAPKCS1.new("256")
signing_key = algorithm.generate_signing_key
signature = algorithm.sign(to_be_signed)
# Signer sends verify key to Verifier
verify_key_string = signing_key.verify_key.serialize
# Verifier
verify_key = OpenSSL::SignatureAlgorithm::RSAPKCS1::VerifyKey.deserialize(verify_key_string)
algorithm = OpenSSL::SignatureAlgorithm::RSAPKCS1.new("256")
algorithm.verify_key = verify_key
algorithm.verify(signature, to_be_signed)After checking out the repo, run bin/setup to install dependencies. Then, run rake spec 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. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
