Does decoding verify signatures?
No. This shows header/payload only. Verification needs the secret/key on a trusted system.

LocalKit processes everything locally in your browser—nothing is uploaded and no account is required. On a shared computer, close the tab afterward and be careful with sensitive clipboard data.
Is my token uploaded?
No. Decoding is local—still avoid pasting production tokens on shared screens. Place your content in the input area above, tweak options if needed, then copy the result into your editor, terminal, or documents. LocalKit processes everything locally in your browser—nothing is uploaded and no account is required. On a shared computer, close the tab afterward and be careful with sensitive clipboard data.
Why is payload unreadable?
Payload must be Base64URL JSON. Encrypted JWTs (JWE) are not plain JSON claims.

LocalKit processes everything locally in your browser—nothing is uploaded and no account is required. On a shared computer, close the tab afterward and be careful with sensitive clipboard data.
What about expired tokens?
You can read exp/nbf claims here; enforcement happens on the server.

Safe for debugging?
Yes for non-secret debugging. Treat real tokens as credentials. Place your content in the input area above, tweak options if needed, then copy the result into your editor, terminal, or documents.
