JWT Token Utils

JWT Token Utils is a powerful OutSystems component that simplifies working with JSON Web Tokens (JWT). It enables secure creation, parsing, validation, and inspection of tokens directly within your OutSystems apps.

🔑 Key Features

• 📤 Full claim and metadata export as JSON
  Effortlessly convert any JWT into a structured JSON object—including standard claims (iat, exp, iss, etc.) and validation results.
  The output can be used for logging, integration, or parsed into a normalized OutSystems structure for further logic and UI binding.

• 🔐 Create and validate JWTs using multiple algorithms
  Supports symmetric (HS256, etc.) and asymmetric (RS256, etc.) signing algorithms. Compatible with PEM and XML key formats.

• ✅ Flexible claim validation with smart wildcard matching
  Easily check for specific values in claims like permissions, even when using patterns like abc.secure.write.*.
  The logic understands dot-separated structures and evaluates wildcards contextually.

• 🔍 Decode and inspect tokens
  Access all standard JWT claims: exp, iat, nbf, iss, aud, and more.

⭐ What Makes It Unique?

Unlike most JWT libraries, JWT Token Utils supports complex nested claim structures (objects or arrays) by flattening them into safe, readable JSON strings.
This ensures seamless compatibility across OutSystems screens, logic flows, and external integrations—even when nested JSON is not natively supported.

🧪 Bonus Utilities

• Roundtrip testing (create → parse → validate)

• Debug helpers for development and QA

• Permission checking via wildcard-aware claim matching
