It supports a fixed-length salt.
The :meth:`~passlib.ifc.PasswordHash.using` method accepts the following optional keywords:
:type salt: str
:param salt:
Optional salt string.
If not specified, one will be autogenerated (this is recommended).
If specified, it must be 2 characters, drawn from the regexp range ``[./0-9A-Za-z]``.
:param bool truncate_error:
By default, des_crypt will silently truncate passwords larger than 8 bytes.
Setting ``truncate_error=True`` will cause :meth:`~passlib.ifc.PasswordHash.hash`
to raise a :exc:`~passlib.exc.PasswordTruncateError` instead.
.. versionadded:: 1.7
:type relaxed: bool
:param relaxed:
By default, providing an invalid value for one of the other
keywords will result in a :exc:`ValueError`. If ``relaxed=True``,
and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning`
will be issued instead. Correctable errors include
``salt`` strings that are too long.

This class implements the BSDi-Crypt password hash, and follows the :ref:`password-hash-api`.
It supports a fixed-length salt, and a variable number of rounds.
The :meth:`~passlib.ifc.PasswordHash.using` method accepts the following optional keywords:
:type salt: str
:param salt:
Optional salt string.
If not specified, one will be autogenerated (this is recommended).
If specified, it must be 4 characters, drawn from the regexp range ``[./0-9A-Za-z]``.
:type rounds: int
:param rounds:
Optional number of rounds to use.
Defaults to 5001, must be between 1 and 16777215, inclusive.
:type relaxed: bool
:param relaxed:
By default, providing an invalid value for one of the other
keywords will result in a :exc:`ValueError`. If ``relaxed=True``,
and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning`
will be issued instead. Correctable errors include ``rounds``
that are too small or too large, and ``salt`` strings that are too long.
.. versionadded:: 1.6
.. versionchanged:: 1.6
:meth:`hash` will now issue a warning if an even number of rounds is used
(see :ref:`bsdi-crypt-security-issues` regarding weak DES keys).
