Decodificador JWT

What is a 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.

Structure

• Header: Typically consists of two parts: the type of the token, which is JWT, and the signing algorithm being used, such as HMAC SHA256 or RSA.
• Payload: Contains the claims. Claims are statements about an entity (typically, the user) and additional data.
• Signature: Used to verify the message wasn't changed along the way.
