jwt

A JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. The claims in a JWT are encoded as a JSON object that is used as the payload of a JSON Web Signature (JWS) structure or as the payload of a JSON Web Encryption (JWE) structure, enabling the claims to be digitally signed or integrity protected with a Message Authentication Code (MAC) and/or encrypted. JWTs are typically used for authentication and authorization purposes. They allow you to verify the identity of users and securely transmit information between applications and services. A JWT consists of three parts: a header, a payload, and a signature. The header typically specifies the type of token and the hashing algorithm used. The payload contains the claims (statements) about an entity (typically, the user) and any additional data. The signature is used to verify that the sender of the JWT is who it says it is and to ensure that the message wasn’t changed along the way.
