Change the Key with CryptoJS [duplicate]

Answer 1

According to the docs at https://code.google.com/archive/p/crypto-js/#Custom_Key_and_IV, you would need to define and supply both the initialisation vector (IV) and the key if you wish to provide a custom key:

var key = CryptoJS.enc.Hex.parse('000102030405060708090a0b0c0d0e0f'); 
var iv = CryptoJS.enc.Hex.parse('101112131415161718191a1b1c1d1e1f'); 
var encrypted = CryptoJS.AES.encrypt("Message", key, { iv: iv });
