我正在尝试在C#中构建一个SSL隧道,它在客户端模式下工作类似于stunnel
;即将未加密的连接转发到加密连接。
为什么这不起作用?
using System;
using System.Net;
using System.Net.Sockets;
using System.Net.Security;
using System.Collections;
using System.Security;
using System.Security.Authentication;
using System.Security.Cryptography.X509Certificates;
using System.Threading;
using System.Text;
using System.IO;
namespace Teststunnel
{
public class SslWrapper
{
public SslWrapper(IPEndPoint remote, int port)
{
listener = new TcpListener (port);
Console.Error.WriteLine ("Established listener");
listenport = port;
server = remote;
listener.Start ();
new Thread (mainEventLoop).Start();
}
private TcpListener listener;
private int listenport;
private IPEndPoint server;
private void mainEventLoop()
{
restart:
Console.Error.WriteLine ("Waiting for connections...");
TcpClient a = listener.AcceptTcpClient ();
Console.Error.WriteLine ("Connection received!");
tunnel (a);
goto restart;
}
private void tunnel(TcpClient nconn)
{
SslStream sstrm = new SslStream (
nconn.GetStream (),
false);
Console.Error.WriteLine (server.ToString());
try
{
sstrm.AuthenticateAsClient (server.ToString());
}
catch (AuthenticationException e)
{
Console.WriteLine("Exception: {0}", e.Message);
if (e.InnerException != null)
{
Console.WriteLine("Inner exception: {0}", e.InnerException.Message);
}
Console.WriteLine ("Authentication failed - closing the connection.");
nconn.Close();
return;
}
}
}
}
在我的主要功能中,我使用new SslWrapper (new IPEndPoint(IPAddress.Parse("198.23.240.183"), 443), 9999);
来调用它。但是,当我尝试连接时,应用程序崩溃:
未处理的例外情况: System.IO.IOException:身份验证或解密失败。 ---> Mono.Security.Protocol.Tls.TlsException:身份验证或解密失败。 在Mono.Security.Protocol.Tls.RecordProtocol.ReadRecordBuffer(Int32 contentType,System.IO.Stream record)[0x00000] in:0 在Mono.Security.Protocol.Tls.RecordProtocol.InternalReceiveRecordCallback(IAsyncResult asyncResult)[0x00000] in:0
是的,我正在使用Mono。但是,我确信我已使用mozroots
导入了所有正确的SSL根证书。我究竟做错了什么?这在Microsoft .NET上也是可重现的。
