Tutorial: How to Extract JWT Data

What is a JWT? A JSON Web Token (JWT) is a compact, self-contained token in JSON format used to securely transmit information between parties. It commonly contains encoded payload data (claims) and a signature for integrity verification, ensuring that the token hasn’t been altered since it was issued. What Data is Stored in a JWT? A JSON Web Token (JWT) usually contains three parts: a header, a payload (claims), and a signature. The payload section often stores user-related data (e.g., user ID, roles, permissions), token expiration time, issuer, and other metadata needed by the application.
