The Header typically consists of the token type and the encryption algorithm used. 2. The Payload primarily records simple and non-sensitive information we store. JWT defines 7 official fields: iss (Issuer): The entity issuing the JWT sub (Subject): The subject of the JWT, i.e., the user the JWT is intended for aud (Audience): The recipients of the JWT exp (Expiration Time): The time after which the JWT expires, in UNIX timestamp format nbf (Not Before): Defines the time before which the JWT must not be accepted for processing iat (Issued At): The time at which the JWT was issued, in UNIX timestamp format jti (JWT ID): The unique identifier for the JWT, used to prevent replay attacks 3. The Signature is a string formed by encoding the Header and Payload in Base64, and then encrypting it with a specified method (e.g., HS256) and a secret key, as follows: HMACSHA256(base64UrlEncode(header) + "." + base64UrlEncode(payload), secret).
