PERTAIN_TOReport

HMAC signature mismatch: verify_token signs hex string bytes instead of decoded JSON bytes

PERTAIN_TOReport

HMAC signature mismatch: payload_hex.encode() vs bytes.fromhex() in token verify

PERTAIN_TORootCause

verify_token() incorrectly converted the hex-encoded payload back to bytes by using payload_hex.encode() (UTF-8 encoding of the hex string) instead of decoding the hex string into the original payload bytes.

PERTAIN_TOProblem

Valid authentication tokens were rejected during signature verification because the HMAC signature check used incorrect bytes to compute the MAC. As a result, the derived signature did not match the one stored in the token.

PERTAIN_TOSolution

All 7 pytest tests pass after fix — test_create_and_verify_token, test_require_auth_valid_token, test_require_role_correct_role, test_require_role_wrong_role. Tension: Tampered token test still correctly returns None. Outcome: All 7 pytest tests pass after fix including test_create_and_verify_token, test_require_auth_valid_token, test_require_role_correct_role, test_require_role_wrong_role.
