    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.

    :type relaxed: bool
    :param relaxed:
        By default, providing an invalid value for one of the other

        and the error can be corrected, a :exc:`~passlib.exc.PasslibHashWarning`

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).
