sha1_crypta&  This class implements the SHA1-Crypt password hash, and follows the :ref:`password-hash-api`.

    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: str
    :param salt:
        Optional salt string.
        If not specified, an 8 character one will be autogenerated (this is recommended).
        If specified, it must be 0-64 characters, drawn from the regexp range ``[./0-9A-Za-z]``.

    :type salt_size: int
    :param salt_size:
        Optional number of bytes to use when autogenerating new salts.
        Defaults to 8 bytes, but can be any value between 0 and 64.

    :type rounds: int
    :param rounds:
        Optional number of rounds to use.
        Defaults to 480000, must be between 1 and 4294967295, 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.
