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. Correctable errors include ``salt`` strings that are too long. .. versionadded:: 1.6 z$1$)Zos_cryptZbuiltinc C s" t dd�r| �| j� dS dS d S )N�testz $1$test$pi/xDtU5WFVRqYS6BMU8X/TF)r �_set_calc_checksum_backend�_calc_checksum_os_crypt�rB r r r$ �_load_backend_os_crypt s z md5_crypt._load_backend_os_cryptc C sb | j | j }t||�}|d u r(| �|�S |�|�rFt|�t|�d krVtj�| ||��|dd � S )Nr' i��) rA r7 r �_calc_checksum_builtin� startswithr. r, r- ZCryptBackendError)rF �secretZconfigrC r r r$ rO s z!md5_crypt._calc_checksum_os_cryptc C s | � | j� dS )NT)rN rR rP r r r$ �_load_backend_builtin% s z md5_crypt._load_backend_builtinc C s t || j�S rE �r= r7 �rF rT r r r$ rR * s z md5_crypt._calc_checksum_builtinN) rH rI rJ rK �namer rA ZbackendsrL rQ rO rU rR r r r r$ r � s c @ s$ e Zd ZdZd Zed�Zdd� ZdS )r ap This class implements the Apr-MD5-Crypt password hash, and follows the :ref:`password-hash-api`.
