Security library for Play framework 2 in Java and Scala: OAuth, CAS, SAML, OpenID Connect, LDAP, JWT...
play-pac4jproject 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 JDK 11 and Play 2.8 (Scala v2.12 or v2.13) and on the pac4j security engine v5. It's available under the Apache 2 license.
Several versions of the library are available depending on the version of the Play framework:
| Play version | pac4j version | play-pac4j version |--------------|---------------|------------------- | 2.0 | 1.7 | play-pac4j_java v1.1.x (Java) / play-pac4j_scala2.9 v1.1.x (Scala) | 2.1 | 1.7 | play-pac4j_java v1.1.x (Java) / play-pac4j_scala2.10 v1.1.x (Scala) | 2.2 | 1.7 | play-pac4j_java v1.2.x (Java) / play-pac4j_scala v1.2.x (Scala) | 2.3 | 1.7 | play-pac4j_java v1.4.x (Java) / play-pac4j_scala2.10 v1.4.x and play-pac4j_scala2.11 v1.4.x (Scala) | 2.4 | 1.9 | play-pac4j v2.3.x (Java & Scala) | 2.5 | 2.x | play-pac4j2.11 and play-pac4j2.12 v3.1.x (Java & Scala) | 2.6 | 3.x | play-pac4j2.11 and play-pac4j2.12 v7.0.x (Java & Scala) Do NOT use Play v2.6.3 and v2.6.5 which have issues in their Cache implementations! | 2.7 | 3.x | play-pac4j2.11 and play-pac4j2.12 v8.0.x (Java & Scala) | 2.7 | 4.x | play-pac4j2.11 and play-pac4j2.12 and play-pac4j_2.13 v9.0.x (Java & Scala) | 2.8 | 4.x | play-pac4j2.12 and play-pac4j2.13 v9.0.x (Java & Scala) | 2.8 | 5.x | play-pac4j2.12 and play-pac4j2.13 v11.0.x-PLAY2.8 (Java & Scala)
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 - 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) A matcher defines whether the security must be applied and can be used for additional web processing
Secureannotation and the
Securitytrait protect methods while the
SecurityFilterprotects 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
CallbackControllerfinishes the login process for an indirect client
LogoutControllerlogs out the user from the application and triggers the logout at the identity provider level
Pac4jScalaTemplateHelpercan 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...
