RS( s� This class provides the fallback behavior for unix shadow files, and follows the :ref:`password-hash-api`.
This class does not implement a hash, but instead provides fallback
behavior as found in /etc/shadow on most unix variants.
If used, should be the last scheme in the context.
* this class will positively identify all hash strings.
* for security, passwords will always hash to ``!``.
* it rejects all passwords if the hash is NOT an empty string (``!`` or ``*`` are frequently used).
* by default it rejects all passwords if the hash is an empty string,
but if ``enable_wildcard=True`` is passed to verify(),
all passwords will be allowed through if the hash is an empty string.
.. deprecated:: 1.6
This has been deprecated due to its "wildcard" feature,
and will be removed in Passlib 1.8. Use :class:`unix_disabled` instead.

and follows the :ref:`password-hash-api`.
This class does not implement a hash, but instead matches the "disabled account"
strings found in ``/etc/shadow`` on most Unix variants. "encrypting" a password
will simply return the disabled account marker. It will reject all passwords,
no matter the hash string. The :meth:`~passlib.ifc.PasswordHash.hash`
method supports one optional keyword:
:type marker: str
:param marker:
Optional marker string which overrides the platform default
used to indicate a disabled account.
If not specified, this will default to ``"*"`` on BSD systems,
and use the Linux default ``"!"`` for all other platforms.
(:attr:`!unix_disabled.default_marker` will contain the default value)
.. versionadded:: 1.6
This class was added as a replacement for the now-deprecated
:class:`unix_fallback` class, which had some undesirable features.

The :meth:`~passlib.ifc.PasswordHash.hash`, :meth:`~passlib.ifc.PasswordHash.genhash`, and :meth:`~passlib.ifc.PasswordHash.verify` methods all require the
following additional contextual keyword:
:type encoding: str
:param encoding:
This controls the character encoding to use (defaults to ``utf-8``).
This encoding will be used to encode :class:`!unicode` passwords
under Python 2, and decode :class:`!bytes` hashes under Python 3.
.. versionchanged:: 1.6
The ``encoding`` keyword was added.
