b. 代碼：

var CryptoJS = require("crypto-js");
// 加密
var key = CryptoJS.MD5(‘hello‘)
key = CryptoJS.enc.Utf8.parse(key)
var iv = CryptoJS.enc.Utf8.parse(‘1234567812345678‘)
var encode = CryptoJS.AES.encrypt(
    ‘hello‘,
    key,
    {
        iv:iv,
        mode:CryptoJS.mode.CBC,
        padding:CryptoJS.pad.ZeroPadding
    }
).toString()
console.log(encode)
// 解密
var bytes  = CryptoJS.AES.decrypt(
    encode,
    key,
