passlib.crypto._md4 -- fallback implementation of MD4
Helper implementing insecure and obsolete md4 algorithm.
used for NTHASH format, which is also insecure and broken,
since it's just md4(password).
Implementated based on rfc at http://www.faqs.org/rfcs/rfc1320.html
.. note::
This shouldn't be imported directly, it's merely used conditionally
by ``passlib.crypto.lookup_hash()`` when a native implementation can't be found.
