好吧，我正在尝试使用 SSL 加密设置 net.tcp 连接我有以下课程

Wcf 接口：

[ServiceContract()]
public interface IServer
{
    [OperationContract]
    void Send(string message);
}

服务器：

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple, UseSynchronizationContext = false)]
class Server : IServer
{
    readonly ServiceHost host;

    public Server()
    {
        host = new ServiceHost(this);
        host.AddServiceEndpoint(typeof(IServer), Program.GetBinding(), string.Format("net.tcp://localhost:{0}/", 1010));
        host.Credentials.ServiceCertificate.Certificate = Program.LoadCert();
        host.Open();
    }

    public void Send(string message)
    {
        Console.WriteLine(message);
    }
}

程序（客户端/服务器）：

class Program
{
    static ChannelFactory<IServer> channelFactory;
    static IServer server;
    static RemoteCertificateValidationCallback callback = null;


    public const int MaxMessageSize = 1024 * 1024 * 2;
    public static Binding GetBinding()
    {
        NetTcpBinding binding = new NetTcpBinding();
        binding.Security.Mode = SecurityMode.Transport;
        binding.Security.Message.ClientCredentialType = MessageCredentialType.None;
        binding.ReaderQuotas.MaxArrayLength = MaxMessageSize;
        binding.ReaderQuotas.MaxBytesPerRead = MaxMessageSize;
        binding.MaxBufferSize = MaxMessageSize;
        binding.MaxReceivedMessageSize = MaxMessageSize;
        binding.MaxBufferPoolSize = binding.MaxBufferSize * 10;
        binding.TransactionFlow = false;
        binding.ReliableSession.Enabled = false;
        binding.Security.Transport.ProtectionLevel = System.Net.Security.ProtectionLevel.EncryptAndSign;
        return binding;
    }


    public static X509Certificate2 LoadCert()
    {
        X509Certificate2 cert = new X509Certificate2();
        cert.Import(@"Test2.pfx", "Test", X509KeyStorageFlags.DefaultKeySet);
        return cert;
    }

    static void Main(string[] args)
    {
        try
        {
            callback = new RemoteCertificateValidationCallback(ValidateCertificate);
            ServicePointManager.ServerCertificateValidationCallback += callback;
            Console.WriteLine("[C]lient or [S]erver?");
            ConsoleKeyInfo key = Console.ReadKey(true);
            if (key.Key == ConsoleKey.S)
            {
                StartServer();
            }
            else if (key.Key == ConsoleKey.C)
            {
                StartClient();
            }
        }
        finally
        {
            if (callback != null)
                ServicePointManager.ServerCertificateValidationCallback -= callback;
        }
    }

    private static void StartClient()
    {
        Console.WriteLine("Starting client mode!");
        Console.Write("Host:");
        string host = Console.ReadLine();
        channelFactory = new ChannelFactory<IServer>(GetBinding());

        server = channelFactory.CreateChannel(new EndpointAddress(string.Format("net.tcp://{0}:{1}/", host, 1010)));
        while (true)
        {
            Console.Write("Message:");
            server.Send(Console.ReadLine());
        }
    }

    private static void StartServer()
    {
        Console.WriteLine("Starting server mode!");
        Server server = new Server();
        Console.ReadKey();
        GC.KeepAlive(server);
    }

    public static bool ValidateCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors sslPolicyErrors)
    {
        Console.WriteLine("ValidateCertificate");
        return true;
    }
}

当服务器和客户端都在同一台计算机上运行时，这可以正常工作（但 ValidateCertificate 从未像应有的那样被调用）。

但是，如果我在不同的计算机上运行它们，我会在客户端出现以下异常：

说明：进程因未处理的异常而终止。异常信息：System.ServiceModel.Security.SecurityNegotiationException 堆栈：

我配置错了什么，为什么当我提供证书时它调用“WindowsStreamSecurityUpgradeProvider”？

或者，如果其他人有一个很好的例子，如何在 net.tcp 上获得传输加密，而客户端和服务器不在同一个域中？

我解决了线上的问题

server = channelFactory.CreateChannel(new EndpointAddress(string.Format("net.tcp://{0}:{1}/", host, 1010)));

我必须添加一个使用以下代码创建的附加参数

EndpointIdentity.CreateX509CertificateIdentity(certificate)
