Reference notes
How JWT decoding works
A JSON Web Token contains Base64URL-encoded sections separated by dots.
Decoding can show the header and payload, but signature verification requires trusted keys and should be treated separately from inspection.
JWT decoder examples
A typical JWT has three sections: header, payload, and signature.
The decoder should display claims such as issuer, subject, audience, and expiration when they are present.
JWT decoder FAQ
Decoding a JWT does not prove it is valid or trusted. Anyone can Base64URL-decode the header and payload.
Sensitive tokens should not be pasted into tools unless the processing model is trusted.
JWT decoder references
Reference material should cover JWT structure, Base64URL encoding, registered claims, and JOSE headers.
Future references can distinguish decoding, validation, and cryptographic verification.
JWT decoder developer examples
Developer examples should show reading token claims and checking timestamps.
Examples should warn that production authorization must verify signatures and expected issuer/audience values.
