This skill provides comprehensive knowledge on using JSON Web Tokens (JWT) for secure authentication and authorization. It covers implementing various cryptographic signing algorithms (such as HS256, RS256, ES256, and EdDSA), validating signatures, enforcing claim constraints (like expiration time), and implementing robust defenses against common JWT vulnerabilities, including algorithm confusion and the 'none' algorithm attack. Ideal for building secure, scalable web APIs.
