About JWT Tokens
JSON Web Token (JWT) is an open standard for securely transmitting information between parties as a JSON object.
A JWT consists of three parts separated by dots (.): header.payload.signature
- Header: Contains the token type and signing algorithm
- Payload: Contains the claims (user data, expiration, etc.)
- Signature: Used to verify the token hasn't been tampered with
Note: This tool only decodes and displays JWT contents. It does not verify the signature. For production use, always verify tokens with the secret key on your server.
