Before you start
What does this tool do?
Inspect JWT claims and optionally verify an HMAC signature with a key you supply locally.
Is the input uploaded?
Source text and files are processed in this browser. Code, token values and file contents are excluded from MakePip tool statistics.
What should I review?
Decoding is not signature verification. HMAC verification does not establish that a token’s issuer, audience or permissions are trusted.
