========================================================
:mod:`passlib.utils.md4` - MD4 message digest algorithm
========================================================
.. module:: passlib.utils.md4
:synopsis: MD4 message digest algorithm
.. warning::
This digest is considered **VERY INSECURE**,
and not suitable for any new cryptographic activities.
Trivial-cost real-world attacks exist for all
password algorithms, stream ciphers, etc, that have
been based on MD4.
Do not use this hash or derived schemes unless you *really* have to.
This module implements the MD4 hash algorithm in pure python,
based on the `rfc 1320 <http://www.faqs.org/rfcs/rfc1320.html>`_ specification of MD4.
.. autoclass:: md4
.. note::
If MD4 support is detected in :mod:`!hashlib`, the :class:`!md4` class in this module
will be replaced by a function wrapping :mod:`!hashlib`'s implementation,
which should be faster, but otherwise behave exactly the same.
