A mruby implementation of JSON Web Token draft 06.

Install by mrbgems

• add conf.gem line to build_config.rb

MRuby::Build.new do |conf|
    # ... (snip) ...
    conf.gem :git => 'https://github.com/ainoya/mruby-jwt.git'
end

Usage

JWT.encode({"some" => "payload"}, "secret")

Note the resulting JWT will not be encrypted, but verifiable with a secret key.

JWT.decode("someJWTstring", "secret")

If the secret is wrong, it will raise a JWT::DecodeError telling you as such. You can still get at the payload by setting the verify argument to false.

JWT.decode("someJWTstring", nil, false)

Caveats

• encryption only supports SHA256 algorithm
• this module is written in only mruby; not c implementation yet.
