    It supports a variable-length salt, and a variable number of rounds.

    The :meth:`~passlib.ifc.PasswordHash.using` method accepts the following optional keywords:

    :type salt: bytes
    :param salt:
        Optional salt bytes.
        If specified, the length must be between 0-1024 bytes.
        If not specified, a %(dsc)d byte salt will be autogenerated (this is recommended).

    :type salt_size: int
    :param salt_size:
        Optional number of bytes to use when autogenerating new salts.
        Defaults to %(dsc)d bytes, but can be any value between 0 and 1024.

    :type rounds: int
    :param rounds:

        Defaults to %(dr)d, but must be within ``range(1,1<<32)``.

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

        will be issued instead. Correctable errors include ``rounds``
        that are too small or too large, and ``salt`` strings that are too long.
