# JWT debugger

Decode JSON Web Tokens, verify signatures and create your own tokens – according to RFC 7519.

> Tokens are credentials. They are processed only in your browser; nothing is transmitted and no keys are fetched from the internet.

## How it works

1. **Paste a token** – Header and payload become readable instantly, timestamps as dates with a note whether the token has expired.
2. **Verify the signature** – With the secret or the public key you can see whether the token is genuine and unmodified.
3. **Create tokens** – In the encoder you build your own test tokens with HMAC, RSA, ECDSA or EdDSA.
