It has no salt and a single fixed round. The :meth:`~passlib.ifc.PasswordHash.using` method accepts a single optional keyword: :param bool truncate_error: By default, this will silently truncate passwords larger than 14 bytes. Setting ``truncate_error=True`` will cause :meth:`~passlib.ifc.PasswordHash.hash` to raise a :exc:`~passlib.exc.PasswordTruncateError` instead. .. versionadded:: 1.7 The :meth:`~passlib.ifc.PasswordHash.hash` and :meth:`~passlib.ifc.PasswordHash.verify` methods accept a single optional keyword: :type encoding: str :param encoding: This specifies what character encoding LMHASH should use when calculating digest. It defaults to ``cp437``, the most common encoding encountered.

The :meth:`~passlib.ifc.PasswordHash.hash`, :meth:`~passlib.ifc.PasswordHash.genhash`, and :meth:`~passlib.ifc.PasswordHash.verify` methods have the following optional keywords: :type user: str :param user: String containing name of user account this password is associated with.
