Microsoft believes that it's no longer safe to decrypt data encrypted with the Cipher-Block-Chaining (CBC) mode of symmetric … See more WebCipher Block Chaining (CBC) For CBC mode, the first step is to generate a random initialization vector (IV) of 16 bytes. Next, XOR the IV and the first 16 bytes of your plaintext to get input for AES. That creates the first 16 bytes of the ciphertext (often the IV is sent as the actual first 16 bytes). how to save electric
