A Rails engine for providing OpenID Connect authorization. Uses the openid_connect gem to turn a Rails app into an OpenID Connect provider.

Use your application as an Open ID provider.

You'll need some kind of user authentication to exist on you application first. Normally we use Devise.

Add this line to your application's Gemfile:

gem 'oidc_provider'

And then execute:

$ bundle

Or install it yourself as:

$ gem install oidc_provider

Install the support stuffs:

• an initializer
• default routes to your routes file

$ rails generate oidc_provider:install

Migrations next:

$ rails oidc_provider:install:migrations
$ rails db:migrate

You will need to generate a unique private key per application.

$ ssh-keygen

Due to Docker Composes' lack of support for multiline .env variables, put a passphrase on it. Then add the key to your application at lib/oidc_provider_key.pem and add the passphrase as an environment variables in your application: ENV["OIDC_PROVIDER_KEY_PASSPHRASE"].
