pac4j security library for Shiro: OAuth, CAS, SAML, OpenID Connect, LDAP, JWT...
buji-pac4jproject is an easy and powerful security library for Shiro web applications and web services which supports authentication and authorization, but also advanced features like CSRF protection. It's based on Java 8, Shiro 1.7 and on the pac4j security engine v5. It's available under the Apache 2 license.
1) A client represents an authentication mechanism. It performs the login process and returns a user profile. An indirect client is for web applications 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
SecurityFiltermust be applied and can be used for additional web processing
SecurityFilterprotects an url 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
CallbackFilterfinishes the login process for an indirect client
LogoutFilterlogs out the user from the application and triggers the logout at the identity provider level
The demo webapp: buji-pac4j-demo is available for tests and implements many authentication mechanisms: Facebook, Twitter, form, basic auth, CAS, SAML, OpenID Connect, JWT...
