Java: Cross-Site Request Forgery (CSRF)

JWTs are self-contained tokens that include all necessary claims for authentication within their payload.

A JSON Web Token (JWT) is composed of three parts: a header, a payload, and a signature. The header typically consists of the token type, which is JWT, and the signing algorithm. The payload contains the claims, which are statements about the entity (typically, the user) and additional data. The signature is used to verify the sender of the JWT and to ensure that the message wasn't changed along the way. In a Java e-commerce app, JWTs can be used to authenticate API requests without needing to store session data on the server.
