  • Certificate Management: Guidance on certificate discovery via JWKS, embedded certificates (x5c), and thumbprints (x5t#S256).
  • Header Validation: Enforcement of critical headers like iat, ttl, and correlationId for security and replay prevention.
  • Use Case: A developer needs to implement the JWS security layer for an X9.150 payment gateway. They can use this Skill to understand how to correctly sign outgoing payment responses and verify incoming payment requests, including handling various certificate discovery methods and freshness checks.
