WebAES is specified for 128-bit block size or 16 bytes which is also the size of the IV. AES key sizes may be 128-bit, 192-bit or 256-bit or 16 byte, 24 byte or 32 byte respectively. They can't be different from those. So use this for AES-256: byte xAESKey [32]; byte xAESIv [16]; This should have nothing to do with the mode of operation. Share WebJan 31, 2016 · The Crypto++ wiki has lots of examples. I mention it because I don't usually see external mode ciphers used with StreamTransformationFilter. Also, you usually use streams in C++, and not FILE*. If you stick with the C++ stuff, then you can use a FileSource and FileSink. – jww Jan 31, 2016 at 20:37 Add a comment 3 Answers Sorted by: 3

WebApr 13, 2013 · 3. Is it explicitly allowed to use the same buffer for plaintext/ciphertext when performing AES encryption/decryption in CBC and ECB modes using Crypto++ (assuming … WebNever use ECB! It is insecure. I recommend an authenticated encryption mode, like EAX or GCM. If you can't use authenticated encryption, use CBC or CTR mode encryption, and then apply a MAC (e.g., AES-CMAC or SHA1-HMAC) to the resulting ciphertext.
