Member Function Documentation

decrypt()

size_t protobuf_comm::BufferDecryptor::decrypt	(	int	cipher,
		const void *	enc,
		size_t	enc_size,
		void *	plain,
		size_t	plain_size
	)

Decrypt a buffer.

Parameters

cipher	cipher ID
enc	encrypted buffer
enc_size	number of bytes in enc
plain	on return contains plain text data
plain_size	size in bytes of plain

Returns

number of bytes that were in the encrypted buffer (this can be shorter if the data did not exactly fit the AES block size.
