It does a single round of hashing, and relies on the username as the salt. The :meth:`~passlib.ifc.PasswordHash.hash`, :meth:`~passlib.ifc.PasswordHash.genhash`, and :meth:`~passlib.ifc.PasswordHash.verify` methods all require the following additional contextual keywords: :type user: str :param user: name of postgres user account this password is associated with. r � c C s8 t |t�r|�d�}t| jddd�}tt|| ��� �S )Nzutf-8�user)Zparam)� isinstancer �encoder r r r � hexdigest)�selfZsecretr � r �=/usr/lib/python3.9/site-packages/passlib/handlers/postgres.py�_calc_checksum+ s zpostgres_md5._calc_checksumN) �__name__� __module__� __qualname__�__doc__�namer Z _hash_prefix�uhZ HEX_CHARSZchecksum_charsZ checksum_sizer r r r r r s )r Zhashlibr ZloggingZ getLoggerr �logZ passlib.utilsr Zpasslib.utils.compatr r r Zpasslib.utils.handlersZutils�handlersr �__all__ZHasUserContextZ StaticHandlerr r r r r �<module> s �
