这里需要强调的就是Java的填充模式是NoPadding，用自己的编写的补零填充内容；

PHP端代码：

<?php
$privateKey = "1234567812345678";
$iv     = "1234567812345678";
$data     = "Test String";

//加密
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);
echo(base64_encode($encrypted));
echo '<br/>';

//解密
$encryptedData = base64_decode("2fbwW9+8vPId2/foafZq6Q==");
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv);
echo($decrypted);
?>

C#端代码：

using System.Linq;
using System.Text;
using System.Security.Cryptography;

namespace pda_demo
{
    class Program
    {
        static void Main(string[] args)
        {
            String encryptData = Program.Encrypt("Test String", "1234567812345678", "1234567812345678");
            Console.WriteLine(encryptData);

            String decryptData = Program.Decrypt("2fbwW9+8vPId2/foafZq6Q==", "1234567812345678", "1234567812345678");
            Console.WriteLine(decryptData);

            Console.Read();
        }

        public static string Encrypt(string toEncrypt, string key, string iv)
        {
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes(key);
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes(iv);
            byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(toEncrypt);

            RijndaelManaged rDel = new RijndaelManaged();
            rDel.Key = keyArray;

            ICryptoTransform cTransform = rDel.CreateEncryptor();
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);

            return Convert.ToBase64String(resultArray, 0, resultArray.Length);
        }

        public static string Decrypt(string toDecrypt, string key, string iv)
        {
            byte[] keyArray = UTF8Encoding.UTF8.GetBytes(key);
            byte[] ivArray = UTF8Encoding.UTF8.GetBytes(iv);
            byte[] toEncryptArray = Convert.FromBase64String(toDecrypt);

            RijndaelManaged rDel = new RijndaelManaged();
            rDel.Key = keyArray;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;
            rDel.Padding = PaddingMode.Zeros;

            ICryptoTransform cTransform = rDel.CreateDecryptor();
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);

            return UTF8Encoding.UTF8.GetString(resultArray);
        }
    }
}

Javascript端代码：

<script src="crypto-js.min.js"></script>
<script src="pad-zeropadding.js"></script>
<script>
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>
