It supports a variable-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, an 8 character one will be autogenerated (this is recommended). If specified, it must be 0-64 characters, drawn from the regexp range ``[./0-9A-Za-z]``. :type salt_size: int :param salt_size: Optional number of bytes to use when autogenerating new salts. Defaults to 8 bytes, but can be any value between 0 and 64. :type rounds: int :param rounds: Optional number of rounds to use. Defaults to 480000, must be between 1 and 4294967295, inclusive. :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 )�saltZ salt_size�roundsz$sha1$� � �@ i S � l �� Zlinearc C s& t j|| j| d�\}}}| |||d�S )N)Zhandler)r r �checksum)�uhZ parse_mc3�ident)�cls�hashr r �chk� r �?/usr/lib/python3.9/site-packages/passlib/handlers/sha1_crypt.py� from_stringS s zsha1_crypt.from_stringFc C s$ |rd n| j }t�| j| j| j|�S )N)r r Z render_mc3r r r )�self�configr r r r � to_stringX s zsha1_crypt.to_string)Zos_cryptZbuiltinc C s" t dd�r| �| j� dS dS d S )N�testz-$sha1$1$Wq3GL2Vp$C8U25GvfHS8qGHimExLaiSFlGkAeTF)r �_set_calc_checksum_backend�_calc_checksum_os_crypt�r r r r �_load_backend_os_cryptd s z!sha1_crypt._load_backend_os_cryptc C sb | j dd�}t||�}|d u r(| �|�S |�|�rFt|�t|�d krVtj�| ||��|dd � S )NT)r � i��)r r �_calc_checksum_builtin� startswith�lenr �excZCryptBackendError)r �secretr r r r r r m s z"sha1_crypt._calc_checksum_os_cryptc C s | � | j� dS )NT)r r# r r r r �_load_backend_builtin{ s z sha1_crypt._load_backend_builtinc C sz t |t�r|�d�}t|v r(tj�| ��| j}td�| j |f �d�}t d|�}t |�D ] }||�}qXt � || j��d�S )Nzutf-8z %s$sha1$%s�asciiZsha1)� isinstancer �encode�_BNULLr r& ZNullPasswordErrorr r r r r r Zencode_transposed_bytes� _chk_offsets�decode)r r' r �resultZ keyed_hmac�_r r r r# � s z!sha1_crypt._calc_checksum_builtin)� r r � � � r � � � � � � � � � � � r � � N)F) �__name__� __module__� __qualname__�__doc__�nameZ setting_kwdsr r Z checksum_sizer Z HASH64_CHARSZchecksum_charsZdefault_salt_sizeZ max_salt_sizeZ salt_charsZdefault_roundsZ min_roundsZ max_roundsZ rounds_cost� classmethodr r Zbackendsr! r r( r# r- r r r r r s0 % r )rE ZloggingZ getLoggerrB �logZ passlib.utilsr r Zpasslib.utils.binaryr Zpasslib.utils.compatr r r Zpasslib.crypto.digestr Zpasslib.utils.handlersZutils�handlersr �__all__r, ZHasManyBackendsZ HasRoundsZHasSaltZGenericHandlerr r r r r �<module> s
