PAHAMI CARA KERJA ALAT

How to decode a JWT

What this decoder shows

The tool decodes the Base64URL header and payload, formats the JSON, and checks whether a numeric exp claim is already expired.

Important limitation

Decoding is not verification. Anyone can decode a JWT; signature verification requires the correct secret or public key and is intentionally not performed here.

Claims to inspect

  • exp tells you when the token expires.
  • iss often identifies the issuer.
  • sub usually identifies the subject or user.

Token handling

Decoding a JWT is not the same as verifying its signature. Avoid using sensitive production tokens in examples, screenshots, or shared sessions.

Pertanyaan yang Sering Diajukan (FAQ)

Does this verify the JWT signature?

No. It only decodes header and payload so you can inspect claims safely.

Is it safe to paste a token here?

The tool runs locally, but you should still avoid pasting highly sensitive production tokens into any page you do not control.

What if my JWT has no exp claim?

The decoder still shows the payload, but it cannot tell whether the token is expired.

Does this verify the signature?

No. It decodes the header and payload and reads exp, but it does not verify the signature or trust the token.
