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. ��markerr Zbsd�*r Nc s> t t| �jf i |��}|d ur:| �|�s4td| ��||_|S )Nzinvalid marker: %r)r r �usingr � ValueError�default_marker)r r- r �subclsr r r r/ x s zunix_disabled.usingc C s@ t |t�rt}n t |t�r t}ntj�|d��| p>|d |v S )Nr r )r r � _MARKER_CHARS�bytes� _MARKER_BYTESr r r )r r �startr r r r � s zunix_disabled.identifyc C s$ t �|� | �|�s t j�| ��dS )NF)r r" r r �InvalidHashError)r r r r r r r# � s zunix_disabled.verifyc K sT |r&t �| |� | jf i |���|�S t �|� | j}|rD| �|�sHJ �t|dd�S )Nr- �Zparam)r Z warn_hash_settings_deprecationr/ r r" r1 r r )r r r r- r r r r � s zunix_disabled.hash�1.7�2.0�Z deprecatedZremovedc C sT | � |�stj�| ��n8|r2t�|� t|dd�S |d urF| j|d�} | �|�S d S )N�configr8 r, )r r r r7 r" r r/ r )r r r< r- r r r �genhash� s zunix_disabled.genhashc C sB | � d�}|d ur>t|dd�}| �|�r2| �|�}|r>||7 }|S )N� r r8 )r r r �enable)r r �outr r r �disable� s zunix_disabled.disablec C sV t |dd�}| jD ]2}|�|�r|t|�d � }|r<| S td��qtj�| ��d S )Nr r8 z cannot restore original hash)r �_disable_prefixes� startswith�lenr0 r r r7 )r r �prefixZorigr r r r? � s zunix_disabled.enable)N)N)N)r$ r% r& r' r( � setting_kwdsr) �tuple�strr3 rB �sys�platformr r1 r* r/ r r# r r �deprecated_methodr= rA r? r+ r r r r r R s. r c @ s~ e Zd ZdZd ZdZdZdZedd� �Z eddd ��Z edd d ��Z e j d d d�edd� ��Ze j d d d�eddd���ZdS )r a~ This class stores passwords in plaintext, and follows the :ref:`password-hash-api`.
