FAQ

Questions JWT Payload Extractor owners ask.

  • 01

    Does this capability verify the JWT signature?

    No, the server focuses exclusively on the deterministic parsing of the payload segment. It does not utilize any cryptographic primitives or secret keys to validate the integrity of the signature segment. Capabilities available: decode_jwt_payload, check_token_expiry, extract_token_identity.

  • 02

    How can I see the expiration date of a token?

    The server extracts the 'exp' claim from the decoded JSON object and compares its Unix timestamp against the current system time to identify if the token's operational window has expired.

  • 03

    Can I extract specific user IDs from the token?

    Yes. After parsing the payload segment into a JSON structure, the server traverses the object hierarchy to retrieve the value associated with any specified key, such as 'sub' or custom user identifiers.
