It supports a fixed-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, one will be autogenerated (this is recommended). If specified, it must be 8 characters, drawn from the regexp range ``[./0-9A-Za-z]``. :type rounds: int :param rounds: Optional number of rounds to use. Defaults to 19, must be between 7 and 30, inclusive. This value is logarithmic, the actual number of iterations used will be :samp:`2**{rounds}`. :type ident: str :param ident: phpBB3 uses ``H`` instead of ``P`` for its identifier, this may be set to ``H`` in order to generate phpBB3 compatible hashes. it defaults to ``P``. :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. .. versionadded:: 1.6 )�salt�rounds�ident� � � � Zlog2z$P$z$H$�P�Hc C sR | � |�\}}|d |dd� |dd � }}}| |t�|�d��||pLd d�S )Nr � � �ascii)r r r �checksum)Z _parse_identr Z decode_int6�encode)�cls�hashr �datar r Zchk� r �;/usr/lib/python3.9/site-packages/passlib/handlers/phpass.py� from_string` s $�zphpass.from_stringc C s8 t d�| jt�| j��d�| j| jp*t d�f }t|�S )Nz%s%s%s%sr � ) r r r Z encode_int6r �decoder r r )�selfr r r r � to_stringk s �zphpass.to_stringc C sl t |t�r|�d�}d| j> }t| j�d�| ��� }d}||k r\t|| ��� }|d7 }q:t�|�� d�S )Nzutf-8r r r ) � isinstancer r r r r �digestr Z encode_bytesr )r ZsecretZ real_rounds�result�rr r r �_calc_checksumu s zphpass._calc_checksumN)�__name__� __module__� __qualname__�__doc__�nameZ setting_kwds�uhZ HASH64_CHARSZchecksum_charsZ min_salt_sizeZ max_salt_sizeZ salt_charsZdefault_roundsZ min_roundsZ max_roundsZ rounds_costr Z default_identZ ident_valuesZ ident_aliases� classmethodr r r$ r r r r r s" ' )r( Zhashlibr ZloggingZ getLoggerr% �logZpasslib.utils.binaryr Zpasslib.utils.compatr r r Zpasslib.utils.handlersZutils�handlersr* �__all__Z HasManyIdentsZ HasRoundsZHasSaltZGenericHandlerr r r r r �<module> s �
