About JWT
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.
JWT Structure
- Header: Contains the token type and signing algorithm
- Payload: Contains the claims (statements about the user and additional data)
- Signature: Used to verify the token hasn't been tampered with
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
