The play-pac4j project is an easy and powerful security library for Play framework v2 web applications and web services which supports authentication and authorization, but also logout and advanced features like CSRF protection. It can work with Deadbolt. It's based on Play 2.7 (and Scala 2.11 or Scala 2.12) and on the pac4j security engine v3. It's available under the Apache 2 license.

Several versions of the library are available for the different versions of the Play framework:

Do NOT use Play 2.6.3 and 2.6.5 versions which have issues in their Cache implementations!

Main concepts and components:

1. A client represents an authentication mechanism. It performs the login process and returns a user profile. An indirect client is for UI authentication while a direct client is for web services authentication:

▸ OAuth - SAML - CAS - OpenID Connect - HTTP - OpenID - Google App Engine - Kerberos - LDAP - SQL - JWT - MongoDB - CouchDB - IP address - REST API

2. An authorizer is meant to check authorizations on the authenticated user profile(s) or on the current web context:

▸ Roles / permissions - Anonymous / remember-me / (fully) authenticated - Profile type, attribute - CORS - CSRF - Security headers - IP address, HTTP method

3. The Secure annotation and the Security trait protect methods while the SecurityFilter protects URLs by checking that the user is authenticated and that the authorizations are valid, according to the clients and authorizers configuration. If the user is not authenticated, it performs authentication for direct clients or starts the login process for indirect clients

4. The CallbackController finishes the login process for an indirect client

5. The LogoutController logs out the user from the application and triggers the logout at the identity provider level

6. The Pac4jScalaTemplateHelper can be used to get the user profile(s) from a Twirl template.

Two demo webapps: play-pac4j-java-demo & play-pac4j-scala-demo are available for tests and implement many authentication mechanisms: Facebook, Twitter, form, basic auth, CAS, SAML, OpenID Connect, JWT...

Test them online: http://play-pac4j-java-demo.herokuapp.com and http://play-pac4j-scala-demo.herokuapp.com.

The latest released version is the , available in the Maven central repository. The next version is under development.
