PHP和.NET通用的加密解密函数类,均使用3DES加解密

最近平台改造,需要写一个PHP和.NET下通用的加密解密类,听说有不少朋友也碰到一些问题,这里和大家分享一下 PHP加解密函数:  function encrypt($string) {
  //加密用的密钥文件
  $key = "xxxxxxxx";
  
  //加密方法
  $cipher_alg = MCRYPT_TRIPLEDES;
  //初始化向量来增加安全性
  $iv = mcrypt_create_iv(mcrypt_get_iv_size($cipher_alg,MCRYPT_MODE_ECB), MCRYPT_RAND);
  
  //开始加密
  $encrypted_string = mcrypt_encrypt($cipher_alg, $key, $string, MCRYPT_MODE_ECB, $iv);
  return base64_encode($encrypted_string);//转化成16进制
//  return $encrypted_string;
 }
 
 function decrypt($string) {
   $string = base64_decode($string);

   //加密用的密钥文件
   $key = "xxxxxxxx";
   
   //加密方法
   $cipher_alg = MCRYPT_TRIPLEDES;
   //初始化向量来增加安全性
   $iv = mcrypt_create_iv(mcrypt_get_iv_size($cipher_alg,MCRYPT_MODE_ECB), MCRYPT_RAND);
   
   //开始加密
   $decrypted_string = mcrypt_decrypt($cipher_alg, $key, $string, MCRYPT_MODE_ECB, $iv);
   return trim($decrypted_string);
 }C#加解密类:using System;
