C#, Java, PHP, Python 和 Javascript 的 AES 加密解密实现

c#里面的AES加密解密

其中加密后以及解密后的字符串都能成功打印,但Console.WriteLine("=3==");之后的输出就没有了,最后输出个线程返回值0,然后就没有然后了。c#不懂,就不深究了,就已执行的部分,是符合要求了。

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);          }      }  }

php的AES加密解密

php代码,php很多东西都是提供好的,直接用函数,但是php目前所知填充模式只有ZeroPadding,于是其他语言就只能跟着它来了:

<?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>

python的AES加密解密

最后加一个python下的aes,需要安装python Crypto:

#!/usr/bin/env python  # -*- coding: utf-8 -*-  from Crypto.Cipher import AES  import base64  PADDING = '\0'  #PADDING = ' '  pad_it = lambda s: s+(16 - len(s)%16)*PADDING    key = '1234567812345678'  iv = '1234567812345678'  source = 'Test String'  generator = AES.new(key, AES.MODE_CBC, iv)  crypt = generator.encrypt(pad_it(source))     cryptedStr = base64.b64encode(crypt)  print cryptedStr  generator = AES.new(key, AES.MODE_CBC, iv)  recovery = generator.decrypt(crypt)  print recovery.rstrip(PADDING)

注意python下需要用'\0'来填充,如果是空格来填充,python加密得到的字符串会跟其他语言不同。另外注意generator在加密的 时候使用过,解密的时候需重新生成再解密,否则解密失败。最后得到的字符串,在python控制台看到尾部是多个NUL这样的东西,要这样 recovery.rstrip(PADDING)去除掉才是原始字符串。

可以看到aes加密的中间结果是byte[]类型,直接new String(byte[])会看不到有意义的中间结果,这里用的是base64,是因为各个语言都有这样的支持。在同个语言内,也有bytesToHexString这样的方式。

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.
