The lagom-pac4j project is an easy and powerful security library for Lagom framework which supports authentication and authorization. It's based on Lagom 1.5/1.6 (and Scala 2.11/2.12/2.13) and 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 Lagom framework:

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 web applications 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 SecuredService interface/trait protect methods in Lagom service 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, the method can be processed with an anonymous profile.

Two demo services demonstrate authenticate/authorize by JWT: (Scala/Sbt demo, Java/Maven demo)
