Primary LanguageRubyMIT LicenseMIT

Devise LULibrary JWT

Provides a simple devise authentication strategy for authenticating by JSON Web Tokens (JWTs) passed either as a GET parameter or as an Authorization header.

Designed to be used with our JWT Server package which provides a central server to authenticate users behind CoSign or similar service that provides a JWT to be used for authentication with other services.

Installation

Add this line to your application's Gemfile:

gem 'devise_lulibrary_jwt'

And then execute:

$ bundle

Or install it yourself as:

$ gem install devise_lulibrary_jwt

Usage

After installing the gem add the following to the model you wish to use for authentication.

devise :jwt_authenticatable, :authentication_keys => [:username], :jwt_create_user => true

The options of authentication_keys and jwt_create_user allow for multiple models to be used with different configuration options, be this using different authentication keys or changed whether the strategy only looks up a user compared to creating the user if they don't exist.

Within the global devise config the following options can be configured, the only required values are jwt_secret, jwt_issuer and jwt_audience.

Parameter Description
jwt_secret The secret used to verify the integrity of the JWT (required)
jwt_issuer The issuer of the JWT (required)
jwt_audience The audience for the JWT (required)
verify_aud Boolean for whether to verify the token audience (false allows for jwt_audience to be nil)
verify_iss Boolean for whether to verify the token issuer (false allows for jwt_issuer to be nil)
verify_iat Boolean for whether to verify the issued at timestamp of the token
jwt_create_user Boolean - Global option for whether to create a user if they don't exist (true) or to just find existing users (false). Can be overridden by setting :jwt_create_user on the devise config line of the model.
