WebMay 12, 2024 · An AES-CBC library can be used to obtain encryption with no padding, even if it is hardwired for one particular, by submitting plaintext of length multiple of the block size and removing the last block of ciphertext. Such library with hardwired padding can also be coerced to ignore the padding on decryption. WebCryptoPP::SecByteBlock key (CryptoPP::AES::DEFAULT_KEYLENGTH); rnd. GenerateBlock (key, key. size ()); CryptoPP::byte iv [ CryptoPP::AES::BLOCKSIZE ]; rnd.
