Each call to the function returns the next counter block. Each counter block is made up by three parts: +------+--------------+-------+ |prefix| counter value|postfix| +------+--------------+-------+ The counter value is incremented by 1 at each call. Args: nbits (integer): Length of the desired counter value, in bits. It must be a multiple of 8. prefix (byte string): The constant prefix of the counter block. By default, no prefix is used. suffix (byte string): The constant postfix of the counter block. By default, no suffix is used. initial_value (integer): The initial value of the counter. Default value is 1. Its length in bits must not exceed the argument ``nbits``. little_endian (boolean): If ``True``, the counter number will be encoded in little endian format. If ``False`` (default), in big endian format. allow_wraparound (boolean): This parameter is ignored. Returns: An object that can be passed with the :data:`counter` parameter to a CTR mode cipher. It must hold that *len(prefix) + nbits//8 + len(suffix)* matches the block size of the underlying block cipher. � � z 'nbits' must be a multiple of 8zGInitial value takes %d bits but it is longer than the counter (%d bits))� counter_len�prefix�suffix� initial_value� little_endian)� ValueError� bit_length)�nbitsr r r r �allow_wraparound�iv_bls �u/builddir/build/BUILD/imunify360-venv-2.6.3/opt/imunify360/venv/lib64/python3.11/site-packages/Crypto/Util/Counter.py�newr s� � �J �� �a����:�;�;�;� � $� $� &� &�E� �u�}�}�� 1� �� �(� )� )� )� !�A�:� � � *� *� � � r N)r r r FF)r � r r �<module>r s# ��24� 4� 4� 4� 4� 4r
