About JWT Encoding

JSON Web Tokens (JWT) are a compact, URL-safe means of representing claims between two parties. The token is signed using HMAC with a secret key, ensuring integrity. JWTs are widely used for authentication, authorization, and information exchange. Never put sensitive data in JWT payloads without encryption — the payload is base64-encoded, not encrypted.
