Cryptojs with iv

WebWhen a symmetric cipher mode requires an IV, the length of the IV must be equal to the block size of the cipher. Hence, you must always use an IV of 128 bits (16 bytes) with AES. AES Secret Key AES provides 128 bit, 192 bit and 256 bit of secret key size for encryption. WebJun 24, 2024 · While the key returned from generateKey (passphrase) which I can use to encrypt and decrypt the realData in CryptoJS.AES.encrypt (realData, generateKey (passphrase), {iv: iv}) is array of bytes. Since bytes is new to me so I don't know if that is hard to brute foce and put back to decryption as key. – Kim Mỹ Jun 24, 2024 at 7:05
