It supports a variable-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 0-8 characters, drawn from the regexp range ``[./0-9A-Za-z]``. :type salt_size: int :param salt_size: Optional number of characters to use when autogenerating new salts. Defaults to 8, but can be any value between 0 and 8. (This is mainly needed when generating Cisco-compatible hashes, which require ``salt_size=4``). :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.
