將PHP代碼轉換爲C＃代碼

Question

<?php 
$pwd = "test"; 
$crypted = base64_encode(pack("H*", sha1(utf8_encode($pwd)))); 
echo("$crypted"); 
?> 

因此，我得到了上面這個PHP代碼，我試圖將它轉換爲C＃代碼。我試過以下，但它沒有相同的輸出。

var bytes = Encoding.UTF8.GetBytes("test"); 
      SHA1 sha = new SHA1CryptoServiceProvider(); 
      var result = sha.ComputeHash(bytes); 
      string hex = Encoding.UTF8.GetString(result, 0, result.Length); 
      byte[] packH = PackH(hex); 
      var base64String = Convert.ToBase64String(packH); 

和方法：

public static byte[] PackH(string hex) 
     { 
      if ((hex.Length % 2) == 1) hex += '0'; 
      var bytes = new byte[hex.Length/2]; 
      for (int i = 0; i < hex.Length; i += 2) 
      { 
       bytes[i/2] = Convert.ToByte(hex.Substring(i, 2), 16); 
      } 
      return bytes; 
     } 

因爲我沒有足夠的信譽來回答我的問題，我將在這裏寫下了答案：d

It seems that i needed to do some extra things:D 

    public static string Crypt(string data) 
      { 
       SHA1 sha = new SHA1Managed(); 
       byte[] buffer = Encoding.UTF8.GetBytes(data); 
       byte[] computeHash = sha.ComputeHash(buffer); 

       string delimitedHexHash = BitConverter.ToString(computeHash); 
       string hexHash = delimitedHexHash.Replace("-", ""); 
       byte[] packH = PackH(hexHash); 
       return Convert.ToBase64String(packH); 
      } 

      public static byte[] PackH(string hex) 
      { 
       if ((hex.Length%2) == 1) hex += '0'; 
       var bytes = new byte[hex.Length/2]; 
       for (int i = 0; i < hex.Length; i += 2) 
       { 
        bytes[i/2] = Convert.ToByte(hex.Substring(i, 2), 16); 
       } 
       return bytes; 
      } 

甚至easyier

Console.WriteLine(Convert.ToBase64String(new SHA1CryptoServiceProvider().ComputeHash(Encoding.ASCII.GetBytes("root"))));

它看起來像在PHP版本中，在你使用base64編碼之前，你也在SHA1函數的輸出上調用pack。

如果我正確解釋PHP版本，您基本上首先對SHA1哈希的輸出進行十六進制編碼，然後對Base編碼的十六進制編碼的字符串進行編碼 - 這與Base64編碼SHA1的輸出不同直接散列這是在C＃版本中發生的事情。
