About JWT

What is JWT?

JSON Web Token (JWT) is a compact, URL-safe means of representing claims between two parties. It consists of three parts: Header, Payload, and Signature.

Common Claims

  • iss (Issuer) - Who issued the token
  • sub (Subject) - Who the token is about
  • aud (Audience) - Who the token is for
  • exp (Expiration) - When the token expires
  • iat (Issued At) - When the token was issued

Security Note

JWTs are encoded, not encrypted. Anyone can decode and read the payload. Never store sensitive data in JWT payloads.
