C＃SSL TcpListener TcpClient

Question

我在.NET中製作遊戲登錄/遊說。我想通過TcpClient & TcpListener通過SSL處理登錄部分。如何使用這兩個類來處理SSL？我不希望需要在客戶機上安裝任何種類的證書。我寧願我能夠將公鑰直接硬編碼到程序中，但我看到的大多數例子都開始處理證書商店。

有什麼建議嗎？

Answer 1

安全套接字層（SSL）僅適用於證書存儲區，如果要使用SSL，則無法避免此問題。

但是，您可以簡單地使用cryptostream進行加密。

     Send s = new Send(); 
     s.sendFile("c:\\boot.ini",tcp.GetStream());

     tripleDES.Key = Encoding.Unicode.GetBytes("foobar12foob".ToCharArray()); 
     tripleDES.IV = Encoding.Unicode.GetBytes("foob".ToCharArray()); 
    } 

    public void sendFile(String fileName, Stream networkStream) 
    { 
     FileStream fin = new FileStream(fileName,FileMode.Open, FileAccess.Read); 

     //Create variables to help with read and write. 
     byte[] bin = new byte[100]; //This is intermediate storage for the encryption. 
     long rdlen = 0; //This is the total number of bytes written. 
     long totlen = fin.Length; //This is the total length of the input file. 
     int len; //This is the number of bytes to be written at a time. 

     CryptoStream encStream = new CryptoStream(networkStream, tripleDES.CreateEncryptor(), CryptoStreamMode.Write); 
     Console.WriteLine("Encrypting..."); 

     //Read from the input file, then encrypt and write to the output file. 
     while(rdlen < totlen)

      rdlen = rdlen + len; 
      //Console.WriteLine("{0} bytes processed", rdlen); 
     } 

     encStream.Close();
