JOSE

JSON Object Signing and Encryption (JOSE) for Ruby.

Heavily based on erlang-jose.

Installation

Add this line to your application's Gemfile:

gem 'jose'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jose

Usage

Better documentation is in progress, but here are a few resources to get started. First, a simple example of key generation and message signing:

# Let's use our secret key "symmetric key" for use with
# the HMAC using SHA-256 (HS256) algorithm.
jwk = JOSE::JWK.from_oct('symmetric key')

# Here is the JSON format of our JWK.
jwk.to_binary
# => "{\"k\":\"c3ltbWV0cmljIGtleQ\",\"kty\":\"oct\"}"

# Now let's sign our message using HS256.
signed = jwk.sign('test', { 'alg' => 'HS256' }).compact
# => "eyJhbGciOiJIUzI1NiJ9.dGVzdA.VlZz7pJCnos0k-WUL9O9RoT9N--2kHSakNIdOg-MIro"

# We use the same key for verification.
verified, message, = jwk.verify(signed)
# => [true, "test"]

Finally, the erlang-jose documentation can provide more ideas of the functionality available in this gem.

Development

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. 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.
