需要在https://code.google.com/p/crypto-js/下载工具包

<script type="text/javascript" src="aes.js"></script>      <script type="text/javascript" src="pad-zeropadding.js"></script>

导入文件，aes.js需要导入crypto-js压缩包中rollups文件夹下的那个aes.js文件，如果引入的是components文件夹下的aes.js是会报错的

  <script type="text/javascript">          var data = "Test String";          var key  = CryptoJS.enc.Latin1.parse('1234567812345678');          var iv   = CryptoJS.enc.Latin1.parse('1234567812345678');            //加密          var encrypted = CryptoJS.AES.encrypt(data,key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.ZeroPadding});            document.write(encrypted.ciphertext);          document.write('<br/>');          document.write(encrypted.key);          document.write('<br/>');          document.write(encrypted.iv);          document.write('<br/>');          document.write(encrypted.salt);          document.write('<br/>');          document.write(encrypted);          document.write('<br/>');            //解密          var decrypted = CryptoJS.AES.decrypt(encrypted,key,{iv:iv,padding:CryptoJS.pad.ZeroPadding});          console.log(decrypted.toString(CryptoJS.enc.Utf8));      </script>

成功加解密，最后解密的字符串串在浏览器的控制台里才能看到。
