WebMar 14, 2024 · We will encrypt the input string with AES-256. First we create two vectors which will hold the key and iv used during encryption (lines 55-56). We use a random generator to generate them (CryptoPP::BlockingRng) on lines 58-60. After that we call encrypt (), decrypt () and hopefully we have got the same string as we passed initially for … WebI found classes and code for re-using a keyed AES instance with other cipher modes but I can't find anything about GCM and the same sorts of classes don't seem to exist.
