Signature: Verification Info

The signature is the cryptographic seal ensuring the token wasn't altered. In this client-side decoder, signature verification occurs entirely in your browser.

HMACSHA256(
base64UrlEncode(header) + "." +
base64UrlEncode(payload),
[YOUR_SECRET_SECRET]
)
This token's raw signature value is: SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
