Return ``a == b``. This function uses an approach designed to prevent timing
analysis by avoiding content based short circuiting behaviour, making it
- appropriate for cryptography. *a* and *b*
- must both be of the same type: either :class:`str` (ASCII only, as e.g.
- returned by :meth:`HMAC.hexdigest`), or any type that supports the
- buffer protocol (e.g. :class:`bytes`).
