FAQ

JWT FAQs

?Does decoding a JWT prove it is valid?

No. Header and payload data are readable without verification, so authenticity requires signature validation with the correct key and algorithm.

?Which signing algorithms does this JWT tool support?

The current signer is intended for the HMAC SHA family choices HS256, HS384, and HS512.

?Should I paste a production JWT secret here?

Use test credentials where possible. Production signing secrets should be handled as sensitive credentials and kept out of unnecessary tooling.
