The goal of this project is to develop a standards compliant [OAuth 2](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-v2/) authorization server and resource server.
An overview of the different OAuth 2.0 grants can be found at [http://alexbilbie.com/2013/02/a-guide-to-oauth-2-grants/](http://alexbilbie.com/2013/02/a-guide-to-oauth-2-grants/).
The resource server allows you to secure your API endpoints by checking for a valid OAuth access token in the request and ensuring the token has the correct permission to access resources.
A tutorial on how to use the authorization server can be found at [http://alexbilbie.com/2013/02/developing-an-oauth2-authorization-server/](http://alexbilbie.com/2013/02/developing-an-oauth2-authorization-server/).
A tutorial on how to use the resource server to secure an API server can be found at [http://alexbilbie.com/2013/02/securing-your-api-with-oauth-2/](http://alexbilbie.com/2013/02/securing-your-api-with-oauth-2/).
The initial code was developed as part of the [Linkey](http://linkey.blogs.lincoln.ac.uk) project which was funded by [JISC](http://jisc.ac.uk) under the Access and Identity Management programme.
This code is principally developed by [Alex Bilbie](http://alexbilbie.com/) ([Twitter](https://twitter.com/alexbilbie)|[Github](https://github.com/alexbilbie)).
