WebApr 24, 2024 · The AES algorithm is an iterative, symmetric-key block cipher that supports cryptographic keys (secret keys) of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. If the data to be encrypted doesn't meet the block size requirement of 128 bits, it must be padded. Padding is the process of filling up the last block to 128 bits. WebJun 30, 2024 · let randomBytes = CryptoJS.lib.WordArray.random (128/8).toString (); iv = CryptoJS.enc.Hex.parse (randomBytes); That means, even if you leave your password and clear text data the same, the output encrypted text (base64 encoded) will change every time. This is all part of the randomization of the data to keep it secure. See That In Action
