the LMHASH and NTHASH algorithms are used in various windows related contexts,
but generally not in a manner compatible with how passlib is structured.
in particular, they have no identifying marks, both being
32 bytes of binary data. thus, they can't be easily identified
in a context with other hashes, so a CryptHandler hasn't been defined for them.
this module provided two functions to aid in any use-cases which exist.
.. warning::
these functions should not be used for new code unless an existing
system requires them, they are both known broken,
and are beyond insecure on their own.
.. autofunction:: raw_lmhash
.. autofunction:: raw_nthash
See also :mod:`passlib.hash.nthash`.
