JWT parsing description

View JWT header, payload and expiration date locally

After pasting the JWT, decode the header and payload locally on the browser, and prompt for issuance, expiration and current status; the tool does not upload tokens.

Only parsing without verification

Decoding can only read the content, but cannot prove that the signature is valid or the data is credible, and the security judgment must be checked by the server.

time field

EXP, IAT, and NBF usually use UNIX seconds, and the pages are converted to local readable times.

protection token

JWT may contain account and permission information, and even if it is locally processed on this site, it should not paste production tokens on untrusted pages.
