PHP解密从C＃.NET RIJNDAEL算法256的String

固定它。

$data = base64_decode(str_replace(' ', '+', $_GET['data']));

无论出于何种原因，PHP是转换+的从GET variablesinto空间

for whatever reason, Php was converting the +'s from the GET variablesinto spaces

我试图解密在C＃.NET被解密的字符串

I am trying to decrypt a string that is being decrypted in C#.NET.

代码的结果不尽相同，有好几次，其中最后一个字符串有一些部分解密，它的其余部分是随机的字符。

The results of the code vary, There were several occasions where the final string had some parts decrypted, and the rest of it was random characters.

大部分时间的解密字符串就是所有的随机字符，我也尝试过一些PHP函数来删除PKCS7填充但他们没有固定的问题。

Most of the time the "decrypted" string is just all random characters, I also tried some Php functions to remove PKCS7 padding but none of them fixed the problem.

我看了网站上的几个类似的问题，但没有一个人帮助。

I've looked at several similar questions on the site but none of them were of help.

C＃

// called as Response.Redirect(url + encryptParams(param));

private string encryptData(string data)
{
    Rijndael aes = Rijndael.Create();
    aes.KeySize = 256;
    aes.BlockSize = 256;
    aes.Mode = CipherMode.CBC;
    aes.Padding = PaddingMode.PKCS7;
    aes.Key = Convert.FromBase64String("b0dJN2c6cklVUX1qUGlFfGMweXRKbH5fSEMuXjAgfQo=");

    ICryptoTransform crypto = aes.CreateEncryptor(aes.Key, aes.IV);
    byte[] txt = ASCIIEncoding.UTF8.GetBytes(data);          
    byte[] cipherText = crypto.TransformFinalBlock(txt, 0, txt.Length);

    return "&data=" + Convert.ToBase64String(cipherText) + "&iv=" + Convert.ToBase64String(aes.IV);
}

PHP的：

   $data = base64_decode($_GET['data']);
   $iv = base64_decode($_GET['iv']);

   echo "<br /><b>IV</b>: " . $_GET['iv'] .
       "<br /><b>Encrypted String</b>: <br /><textarea>".$_GET['data']."</textarea>" .
       "<br /><b>key size:</b> " . mcrypt_get_key_size ( MCRYPT_RIJNDAEL_256,  MCRYPT_MODE_CBC) .
       "<br /><b>block size:</b> " . mcrypt_get_block_size ( MCRYPT_RIJNDAEL_256,  MCRYPT_MODE_CBC) .
       "<br /><b>cipher:</b> " . mcrypt_get_cipher_name ( MCRYPT_RIJNDAEL_256 ) .
       "<br /><b>iv size:</b> " .  mcrypt_get_iv_size  ( MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC) . "<br />"; 

   echo "Result: " . 
      mcrypt_decrypt
      (
          MCRYPT_RIJNDAEL_256,
          base64_decode("b0dJN2c6cklVUX1qUGlFfGMweXRKbH5fSEMuXjAgfQo="),
          $data,
          MCRYPT_MODE_CBC,
          $iv
       );

PHP的输出：
