The timestamp validation logic in check_sign uses time.time() - 300 < int(e, 36) which could allow future timestamps to be valid. Consider using abs(time.time() - int(e, 36)) < 300 to reject both old and future timestamps, or add an explicit check that int(e, 36) <= time.time() to prevent acceptance of future-dated signatures.
