多语言AES加解密算法【转】

key和iv向量一定要16字节

C#

     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;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;
            rDel.Padding = PaddingMode.Zeros;
            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);
        }

JAVA

PHP

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

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

JAVASCRIPT

Javascript下aes加解密，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>
