//加密
    var data = '世界你好';
    var key  = CryptoJS.enc.Utf8.parse('dvyYRQlnPRCMdQSe');
    var iv   = CryptoJS.enc.Utf8.parse('face0123456789ai');
    var a = CryptoJS.AES.encrypt(data, key, {iv:iv,mode:CryptoJS.mode.CBC}).toString();
    console.log(a);


    //解密
    var ikey  = CryptoJS.enc.Utf8.parse('dvyYRQlnPRCMdQSe');
    var iiv   = CryptoJS.enc.Utf8.parse('face0123456789ai');
    var pwd = a;
    var b = CryptoJS.AES.decrypt(pwd, ikey, {iv:iiv,mode:CryptoJS.mode.CBC}).toString(CryptoJS.enc.Utf8);
    console.log(b);

需要引入aes.js，和pad-zeropadding-min.js
