decrypt_data()

(int, int) decrypt_data	(	RandomAccessStream	input_stream,
		int	start,
		int	count,
		bytearray	out_data,
		bytearray	key,
		bytearray	nonce,
		bytearray | None	header_data,
		bool	integrity,
		bytearray | None	hash_key,
		int | None	chunk_size,
		int	buffer_size,
		str | None	shm_cancel_name = None )

Decrypt the data stream. Do not use directly use decrypt() instead.
:param input_stream: The Stream to be decrypted.
:param start: The start position of the stream to be decrypted.
:param count: The number of bytes to be decrypted.
:param out_data: The buffer with the decrypted data.
:param key: The AES key to be used.
:param nonce: The nonce to be used.
:param header_data: The header data to be used.
:param integrity: True to verify integrity.
:param hash_key: The hash key to be used for integrity verification.
:param chunk_size: The chunk size.
:param buffer_size: The buffer size.
:param shm_cancel_name: The shared memory cancelation name
:raises IOError: Thrown if there is an error with the stream.
:raises SalmonSecurityException: Thrown if there is a security exception with the stream.
:raises IntegrityException: Thrown if the stream is corrupt or tampered with.
