Args: data (byte string): The piece of binary data to encode. marker (string): The marker for the PEM block (e.g. "PUBLIC KEY"). Note that there is no official master list for all allowed markers. Still, you can refer to the OpenSSL_ source code. passphrase (byte string): If given, the PEM block will be encrypted. The key is derived from the passphrase. randfunc (callable): Random number generation function; it accepts an integer N and returns a byte string of random data, N bytes long. If not given, a new one is instantiated. Returns: The PEM block, as a string. .. _OpenSSL: https://github.com/openssl/openssl/blob/master/include/openssl/pem.h Nz-----BEGIN %s----- � � � z2Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,%s zEmpty passwordc �^ �� g | ])}t t �||d z � � � � � ��*S )�0 )r r )�.0�i�datas ��o/builddir/build/BUILD/imunify360-venv-2.5.3/opt/imunify360/venv/lib64/python3.11/site-packages/Crypto/IO/PEM.py� <listcomp>zencode.<locals>.<listcomp>Z sE �� � 0� 0� 0�� �J�t�A�a�"�f�H�~�.�.�/�/� 0� 0� 0� r r � z-----END %s-----)r r r r �new�MODE_CBCr r �upper�encryptr � block_size� ValueError�range�len�join) r �marker� passphrase�randfunc�out�salt�key�objenc�chunkss ` r r r / sA �� �0 ��#�� �6� )�C�� +��x��{�{���Z��r�1�c�2�2�� �v�c�J�&��a��C�8�8�8����#�t�}�d�3�3�� �F� �'�$�-�-�%�%�'�'� (� (�)� )�� �~�~�c�$��(9� :� :�;�;��� � ��)�*�*�*�0� 0� 0� 0� �Q��D� � �2�.�.�0� 0� 0�F��2�7�7�6�?�?��C�� �� &�&�C� �Jr c � � dg}|dz dz }t |� � D ]I}t j |d | z |z � � � � � }|� |� � �Jd� |� � d |� S )Nr � r ���)r& r r �digest�appendr( )r r- �key_len�d�m�_�nds r �_EVP_BytesToKeyr; a s~ � � ��A� �2� �2� �A� �1�X�X� � �� �W�Q�r�U�T�\�D�(� )� )� 0� 0� 2� 2�� ���� � � � � �8�8�A�;�;�x��x� � r c �0 � t j d� � }|� | � � }|st d� � �|� d� � }t j d� � }|� | � � }|r|� d� � |k rt d� � �| � dd� � � � � }|d � d� � �r:|st d � � �|d � d � � }t |� � d k s |d d k rt d� � �|d � d� � \ }}t t |� � � � }d} |dk r3t ||d� � } t j | t j |� � } �n`|dk r3t ||d� � } t! j | t j |� � } �n'|dk r:t ||dd� d� � } t# j | t" j |� � } n�|dk r:t ||dd� d� � } t# j | t" j |� � } n�|dk r:t ||dd� d� � } t# j | t" j |� � } ng|� � � dk r=t ||dd� d� � } t# j | t" j |� � � } d } nt d |z � � �|d d� }nd} t) d� |dd � � � � � } d } | rB| r)t- | � | � � | j � � } n| � | � � } d} | || fS ) a Decode a PEM block into binary. Args: pem_data (string): The PEM block. passphrase (byte string): If given and the PEM block is encrypted, the key will be derived from the passphrase. Returns: A tuple with the binary data, the marker string, and a boolean to indicate if decryption was performed. Raises: ValueError: if decoding fails, if the PEM file is encrypted and no passphrase has been provided or if the passphrase is incorrect. z\s*-----BEGIN (.*)-----\s+z Not a valid PEM pre boundaryr z-----END (.*)-----\s*$z Not a valid PEM post boundary� r zProc-Type:4,ENCRYPTEDz-PEM is encrypted, but no passphrase available� �:r zDEK-Infoz$PEM encryption format not supported.�,TzDES-CBCr z DES-EDE3-CBC� z AES-128-CBCNr z AES-192-CBCz AES-256-CBC� z id-aes256-gcm)�nonceFz(Unsupport PEM encryption algorithm (%s).r3 )�re�compile�matchr% �group�search�replace�split� startswithr' r r r; r r r! r r �lower�MODE_GCMr r( r �decryptr$ )�pem_datar* �rr8 r) �lines�DEK�algor- �paddingr. �objdecr �enc_flags r r r j sj � �( � �0�1�1�A� ������A� � 9��7�8�8�8� �W�W�Q�Z�Z�F� � �,�-�-�A� ������A� � :����� � �f�$�$��8�9�9�9� � � �S�"� %� %� +� +� -� -�E� �Q�x���2�3�3� "�� N� � L�M�M� M��A�h�n�n�S�!�!�� �s�8�8�q�=�=�C��F�j� 0� 0� � C�D�D� D���V�\�\�#�&�&� ��d���� � �'�'���� �9� � �!�*�d�A�6�6�C��W�S�#�,��5�5�F�F� �^� #� #�!�*�d�B�7�7�C��X�c�4�=�$�7�7�F�F� �]� "� "�!�*�d�2�A�2�h��;�;�C��W�S�#�,��5�5�F�F� �]� "� "�!�*�d�2�A�2�h��;�;�C��W�S�#�,��5�5�F�F� �]� "� "�!�*�d�2�A�2�h��;�;�C��W�S�#�,��5�5�F�F� �Z�Z�\�\�_� ,� ,�!�*�d�2�A�2�h��;�;�C��W�S�#�,�d�;�;�;�F��G�G� � G�$� N�O�O� O��a�b�b� ����� �b�g�g�e�A�b�D�k�*�*� +� +�D��H� � � � (��� � ��-�-�v�/@�A�A�D�D� �>�>�$�'�'�D��� �&�(� #�#r )NN)N)�__all__rD �binasciir r r r � Crypto.Hashr �Crypto.Util.Paddingr r � Crypto.Cipherr r r �Crypto.Protocol.KDFr � Crypto.Randomr �Crypto.Util.py3compatr r r r; r � r r �<module>r` s ��D �X� �� � � � � ?� ?� ?� ?� ?� ?� ?� ?� ?� ?� ?� ?� � � � � � � *� *� *� *� *� *� *� *� (� (� (� (� (� (� (� (� (� (� &� &� &� &� &� &� *� *� *� *� *� *� 0� 0� 0� 0� 0� 0� 0� 0�/� /� /� /�d!� !� !�S$� S$� S$� S$� S$� S$r
