HTTPS代理实现(SSLStream)

我编写了一个控制台应用程序作为代理服务器。现在我也想实现SSL。不喜欢解密任何流量。就像普通的https代理一样。我不知道该怎么继续下去。

var host = text.Remove(0, connectText.Length + 1);
var hostIndex = host.IndexOf(" ", StringComparison.Ordinal);
var hostEntry = host.Remove(hostIndex).Split(new []{":"}, StringSplitOptions.None);
requestClient.Connect(hostEntry[0], Convert.ToInt32(hostEntry[1]));
requestStream = requestClient.GetStream();
var sslStream = new SslStream(requestStream, false, (x1,x2,x3,x4) => true);
sslStream.AuthenticateAsClient(hostEntry[0]);
const string sslResponse = "HTTP/1.0 200 Connection established'r'n'r'n";
var sslResponseBytes = Encoding.UTF8.GetBytes(sslResponse);
proxyStream.Write(sslResponseBytes, 0, sslResponseBytes.Length);
proxyStream.Flush();

我应该直接写一切到sslStream?浏览器连接proxyClient怎么样?我是否需要包装流，或者我可以直接将所有内容写入proxyStream ?我应该使用AuthenticateAsServer并以某种方式从AuthenticateAsClient传递证书吗?

1. IE向我的代理发出CONNECT请求
2. 我的代理看到它是一个连接请求，并获得的IP:端口目的地(例如www.hotmail.com:443)
3. 我的代理创建一个新的TCP连接到www.hotmail.com:443
4. 我的代理从这个目的地获得一个SslStream并调用AuthenticateAsClient -这给了我的代理一个安全的连接到Hotmail的东西
然后我的代理发送一个"HTTP/1.0 200"消息回浏览器，说连接成功。
5. 我的代理然后从浏览器连接中获得一个SslStream并调用AuthenticateAsServer -给我的代理一个安全的连接到浏览器端

我看到了这个，但是如何AuthenticateAsServer没有假证书。我能把它写成正常的格式吗还是我应该考虑别的?
