Php解密来自C#.NET RIJNDAEL 256的字符串

$data = base64_decode(str_replace(' ','+',$_GET['data']));@H_489_3@ 
 
无论出于何种原因,php正在将GET变量转换为空格

我试图解密在C#.NET中解密的字符串.
 
 
代码的结果各不相同,有几次最后的字符串解密了一些部分,其余部分是随机字符.
 
 
大多数时候“解密”字符串只是所有随机字符,我也尝试了一些php函数来删除PKCS7填充,但没有一个修复了这个问题.
 
 
我在网站上看了几个类似的问题,但没有一个是有帮助的.
 
 
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,txt.Length);

    return "&data=" + Convert.ToBase64String(cipherText) + "&iv=" + Convert.ToBase64String(aes.IV);
}@H_489_3@ 
 
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
       );@H_489_3@ 
 
php输出：
