PHP、Java、.Net和Javascript的AES加密解密实现 - 摘要: 本文讲的是PHP、Java、.Net和Javascript的AES加密解密实现, # PHP篇 <?php $privateKey = "1234567812345678"; $iv = "1234567812345678"; $data = "Test String"; /

# PHP

<?php    $privateKey = "1234567812345678";    $iv     = "1234567812345678";    $data   = "Test String";    //加密    $encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);    echo '<br/>';    echo(base64_encode($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篇

    <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>

# Java篇

# .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.
