Frequently Asked Questions
Does this decoder verify token secret signatures?
This is a decoder, not a validator. Signature validation requires your secret key. To ensure total client safety, we do not request or import secret validation keys.
What fields are standard in JWT payloads?
Standard fields (claims) include "sub" (subject), "iss" (issuer), "exp" (expiry timestamp), and "iat" (created timestamp).
Where are decoded cookies or secrets held?
Nowhere! Deconstructing text algorithms operate purely within active memory segments of your local browser.
