PHP mcrypt_encrypt到.NET [英] PHP mcrypt_encrypt to .NET

问题描述

我几乎已经失去了头发，头脑和其他所有东西！我一直在尝试将此PHP函数转换为C#:

I have almost lost my hair, mind and everything else! I have been trying to convert this PHP function to C#:

function  encrypt_decrypt($action, $string) {
  $output = false;
  $key = 'My strong secret key';
  // initialization vector
  $iv = md5(md5($key));
  $output = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $string, MCRYPT_MODE_CBC, $iv);
  $output = bin2hex($output);
  return $output;
}

我一直在使用Rijandel Class:

I have been working with Rijandel Class:

function  encrypt_decrypt(string password) {
  UTF8Encoding encoding = new UTF8Encoding();
  // For consistency with PHP function, MD5Encrypt applies MD5 encryption and does a bin2hex
  byte[] Key = Encoding.ASCII.GetBytes(MD5Encrypt(password).ToLower());
  byte[] IV = Encoding.ASCII.GetBytes(MD5Encrypt(MD5Encrypt(password).ToLower()).ToLower());

  RijndaelManaged rj = new RijndaelManaged();
  rj.BlockSize = 256;
  rj.KeySize = 256;
  rj.Key = Key;
  rj.IV = IV;
  rj.Mode = CipherMode.CBC;
  MemoryStream ms = new MemoryStream();

  using (CryptoStream cs = new CryptoStream(ms, rj.CreateEncryptor(Key, IV), CryptoStreamMode.Write))
  {
    using (StreamWriter sw = new StreamWriter(cs))
    {
      sw.Write(message);
      sw.Close();
    }
    cs.Close();
  }
  byte[] encoded = ms.ToArray();                
  string output = "";
  foreach (var ele in encoded)
  {
    output += ele.ToString("X2");
  }

  return output;
}

我一直在用C#代码验证PHP代码的输出，但它们不匹配. ( http://writecodeonline.com/php/).任何反馈将不胜感激.

I have been validating the output of the PHP code with that from the C# code and they do not match. (http://writecodeonline.com/php/). Any feedback would be appreciated.

推荐答案

尝试以下方法:

        using (RijndaelManaged myRijndael = new RijndaelManaged())
        {

            myRijndael.Key = Encoding.UTF8.GetBytes(password);
            string strIv16 = "\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0\x0";
            myRijndael.IV = Encoding.UTF8.GetBytes(strIv16);

            // Encrypt the string to an array of bytes. 
            byte[] encrypted = EncryptStringToBytes(message, myRijndael.Key, myRijndael.IV);
            string output = Convert.ToBase64String(encrypted);

        }
