http4s-pac4j project is an easy and powerful security library for http4s web applications and web services which supports authentication and authorization, but also logout and advanced features like session fixation and CSRF protection. It's based on Http4s 0.21 and on the pac4j security engine v3. The library is cross-built for Scala 2.12 and 2.13. It's available under the Apache 2 license.
- A client represents an authentication mechanism. It performs the login process and returns a user profile. An indirect client is for web application authentication while a direct client is for web services authentication:
▸ OAuth - SAML - CAS - OpenID Connect - HTTP - OpenID - Google App Engine - LDAP - SQL - JWT - MongoDB - CouchDB - Kerberos - IP address - Kerberos (SPNEGO) - REST API
- 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
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
CallbackRoutefinishes the login process for an indirect client
LogoutRoutelogs out the user from the application and triggers the logout at the identity provider level.

The demo webapp for http4s-pac4j: http4s-pac4j-demo is available for tests and implements many authentication mechanisms: Facebook, Twitter, form, basic auth, CAS, SAML, OpenID Connect, JWT...
