It supports a variable-length salt, and a variable number of rounds. The :meth:`~passlib.ifc.PasswordHash.using` method accepts the following optional keywords: :param salt: Optional raw salt string. If not specified, one will be autogenerated (this is recommended). :param salt_size: Optional number of bytes to use when autogenerating new salts. Defaults to 16 bytes, but can be any non-negative value. :param rounds: Optional number of rounds to use. Defaults to 480000, must be between 1 and 4294967295, inclusive. :param variant: Optionally specifies variant of FSHP to use. * ``0`` - uses SHA-1 digest (deprecated). * ``1`` - uses SHA-2/256 digest (default). * ``2`` - uses SHA-2/384 digest. * ``3`` - uses SHA-2/512 digest. :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� salt_size�rounds�variantz{FSHP� Ni S � l �� Zlinear)Zsha1� )Zsha256� )Zsha384�0 )Zsha512�@ )r r � � c C s g | ]}t |�|f�qS � )r )�.0�kr r �9/usr/lib/python3.9/site-packages/passlib/handlers/fshp.py� <listcomp>_ � zfshp.<listcomp>c C s g | ]\}}|d |f�qS )r r )r r �vr r r r ` r c s. t t| �jf i |��}|d ur*| �|�|_|S )N)�superr �using� _norm_variant�default_variant)�clsr �kwds�subcls�� __class__r r r f s z fshp.usingc sr |� d�| _|d ur | �|�}n2| jrJ| j}| �|�|ksRJ d|f ��ntd��|| _tt| �jf i |�� d S )N� use_defaultszinvalid default variant: %rzno variant specified) �getr' r r! � TypeErrorr r r �__init__)�selfr r# r% r r r* u s z fshp.__init__c C sp t |t�r|�d�}t |t�rHz| j| }W n tyF td��Y n0 t |t�sZtd��|| j vrltd��|S )N�asciizinvalid fshp variantz'fshp variant must be int or known alias) � isinstance�bytes�decoder �_variant_aliases�KeyError� ValueError�intr) � _variant_info)r" r r r r r � s zfshp._norm_variantc C s | j | j d S )Nr �r4 r �r+ r r r � checksum_alg� s zfshp.checksum_algc C s | j | j d S )Nr r5 r6 r r r � checksum_size� s zfshp.checksum_sizez� ^ \{FSHP (\d+)\| # variant (\d+)\| # salt size (\d+)\} # rounds ([a-zA-Z0-9+/]+={0,3}) # digest $c C s� t |dd�}| j�|�}|s(tj�| ��|�dddd�\}}}}t|�}t|�}t|�}zt|� d��}W n t y� tj� | ��Y n0 |d |� }||d � }| ||||d�S )Nr, �hashr r r � )r �checksumr r ) r � _hash_regex�match�uh�excZInvalidHashError�groupr3 r �encoder) ZMalformedHashError) r" r9 �mr r r �datar �chkr r r � from_string� s zfshp.from_stringc C s4 | j }| j}tt|| ��}d| jt|�| j|f S )Nz{FSHP%d|%d|%d}%s)r; r r r r �lenr )r+ rD r rC r r r � to_string� s zfshp.to_stringc C s. t |t�r|�d�}t| j| j|| j| jd�S )Nzutf-8)�digest�secretr r Zkeylen)r- r rA r r7 r r r8 )r+ rI r r r �_calc_checksum� s �zfshp._calc_checksum)N)N)&�__name__� __module__� __qualname__�__doc__�nameZ setting_kwdsr> ZPADDED_BASE64_CHARSZchecksum_charsr �identZdefault_salt_sizeZ max_salt_sizeZdefault_roundsZ min_roundsZ max_roundsZ rounds_costr! r4 �dictr r0 � classmethodr r r* r �propertyr7 r8 �re�compile�Xr< rE rG rJ � __classcell__r r r% r r sN )� �� � ) rN �base64r r rT ZloggingZ getLoggerrK �logZ passlib.utilsr Zpasslib.utils.handlersZutils�handlersr> Zpasslib.utils.compatr r r r Zpasslib.crypto.digestr �__all__Z HasRoundsZ HasRawSaltZHasRawChecksumZGenericHandlerr r r r r �<module> s �
