pac4j is a versatile and powerful Java security framework that simplifies authentication, user profile management, and authorization across multiple frameworks and protocols.
Security engine for Java (authentication, authorization, multi frameworks): OAuth, CAS, SAML, OpenID Connect, LDAP, JWT...
pac4j is primarily used by Java developers to secure web applications and web services by integrating various authentication and authorization mechanisms seamlessly. It supports multiple Java frameworks and a wide range of identity providers, making it ideal for projects requiring flexible and comprehensive IAM solutions.
Ensure you select the pac4j version compatible with your JDK to avoid compatibility issues. Leveraging the modular implementations for your specific Java framework can simplify integration. Properly configure authorizers and clients to match your security policies, and consider enabling web security features like CSRF and CORS for comprehensive protection.
Choose the pac4j version compatible with your JDK (v6.x for JDK 17, v5.x for JDK 11, v4.x for JDK 8)
