#Javascript篇

<script type="text/javascript">
        var data = "Test String";
        var key  = CryptoJS.enc.Latin1.parse('1234567812345678');

        //加密
        var encrypted = CryptoJS.AES.encrypt(data,key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.ZeroPadding});

# .Net篇
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security.Cryptography;
namespace test
{
class Class1
{
static void Main(string[] args)
{
Console.WriteLine("I am comming");
String source = "Test String";
String encryptData = Class1.Encrypt(source, "1234567812345678", "1234567812345678");
Console.WriteLine("=1==");
Console.WriteLine(encryptData);
Console.WriteLine("=2==");
String decryptData = Class1.Decrypt("2fbwW9+8vPId2/foafZq6Q==", "1234567812345678", "1234567812345678");
Console.WriteLine(decryptData);
Console.WriteLine("=3==");
Console.WriteLine("I will go out");
}
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);
}
}
}
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.
以上就介绍了PHP、Java、Net和Javascript的AES加密解密实现，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
