This is a token-based authentication service using JWT (RFC 7519), using the jose4j JWT library. JWT is a much simpler, web-friendly and secure version of SAML (Security Assertion Markup Language). Check out www.jwt.io for more information
The project implements a small, but useful, non-interoperable subset of OAuth2. The interoperability provided by OAuth2 makes it an overcomplicated protocol with a number of security pitfalls that need to be avoided. See www.oauthsecurity.com for some examples.
This implementation implements bearer tokens, refresh tokens, 2048 bit RSA-256 signatures and simple password authentication.
I wrote this code to familiarise myself with Scala, the Play Framework, jQuery, HTTP Cross Origin Resource Sharing (CORS), GitHub and Amazon Web Services (AWS).
An example application can be launched as a virtual machine running in the AWS Free Tier. Everything can be automated with the provided Cloudformation template: https://raw.githubusercontent.com/tkeetch/jwt-play-server/master/conf/cloudformation/jwt-play-server.template
Note: When launched using in the free-tier by default it will take around 10-15 mins for the service to fully launch.
One the app has launched, visit the test page: https://<public_aws_ip>/. Until the app has launched, nginx will display an error. Plus, you will get a certificate error because of the use of a self-signed certificate.
User accounts can be configured by editing the /conf/users.conf file which is in the standard HOCON format used by the Play Framework. tom/tom is one valid set of credentials.
