Question 1

How to set up OAuth authentication with vertx-pac4j?

Accepted Answer

Configure an OAuth client in the security configuration, define a callback handler for web applications, and apply the SecurityHandler to protected routes. The demo webapp provides examples with providers like Facebook and Twitter.

Question 2

Is vertx-pac4j compatible with Vert.x 4?

Accepted Answer

No, it's built for Vert.x 5.0 and Java 17, as stated in the README. For Vert.x 4, you might need to use an older version or plan a migration, which could involve breaking changes.

Can I use vertx-pac4j for API security with JWT tokens?

Accepted Answer

Yes, it supports JWT authentication through direct clients, allowing you to validate tokens and extract user profiles for securing web services, as mentioned in the key features.

Question 4

vertx-pac4j vs Spring Security for Vert.x applications?

Accepted Answer

vertx-pac4j offers tighter integration with Vert.x's reactive stack and multi-protocol support via pac4j, while Spring Security is more general-purpose. Choose vertx-pac4j for native Vert.x projects, but Spring Security might be better in Spring-based ecosystems.

Question 5

How does logout work with multiple identity providers?

Accepted Answer

The LogoutHandler logs out the user from the application and can trigger logout at the identity provider level, supporting integrated flows for protocols like SAML and OpenID Connect, as described in the README.

Question 6

Are there performance implications with vertx-pac4j?

Accepted Answer

Being built on Vert.x, it benefits from non-blocking, reactive performance, but the overhead of security checks and multiple handlers should be profiled in high-throughput scenarios, as no benchmarks are provided in the README.
