System Documentation

What problem does it solve?

This Skill provides a blueprint to securely implement JWT-based authentication and authorization in Java applications, including verification, claims validation, key rotation, token lifetimes, and safe error handling.

Core Features & Use Cases

  • JWT parsing and signature verification with algorithm allowlists and key rotation (JWKS support)
  • Strict claims validation for iss, aud, exp, nbf, iat, and optional typ/jti
  • RBAC/ABAC/Scopes-based authorization modeling and safe error handling
  • Operational safety: logging guidelines, observability, and revocation strategies
  • Use Case: protecting REST APIs and microservices that rely on OIDC/OAuth2 providers

Quick Start

Configure your API to verify JWTs with a verifier and rotate JWKS keys as needed.
