    //解密

JavaScript代码（没测试）

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

跨语言加解密的要求是：AES/CBC/ZeroPadding 128位模式，key和iv一样，编码统一用utf-8。不支持ZeroPadding的就用NoPadding.
