无法获得双向 SSL 以与 HttpWebRequest 一起使用

Question

我有一个 WCF 服务应用程序，它应该连接到另一个服务器 X 以检索数据。当服务器 X 配置了单向 SSL 时，WCF 服务应用程序能够毫无问题地连接到它。但是当服务器 X 配置了双向 SSL 时，WCF 服务应用程序将无法连接到它。

WCF 服务应用程序使用自签名证书。该证书在没有私钥的情况下导出到 .cer 文件中，并导入到服务器 X 的信任库中。 WCF 服务应用程序的代码中使用了相同的导出证书：

string URL = "https://11.205.112.49:5311/Ping";
HttpWebRequest Request = (HttpWebRequest)WebRequest.Create(URL);
X509Certificate2 Certificate = new X509Certificate2("F:\cert.cer");
Request.ClientCertificates.Add(Certificate);
Request.Method = "GET";
HttpWebResponse Response = (HttpWebResponse)Request.GetResponse();

上面代码的最后一行将抛出 WebException 并显示以下消息：

The request was aborted: Could not create SSL/TLS secure channel.

上面的错误没有提供太多细节。

感谢帮助。

提前致谢。

编辑：

这是我的整个程序：

using System.Net;
using System.Security.Cryptography.X509Certificates;
using System.IO;

namespace TestTwoWaySSL
{
    class Program
    {
        static void Main(string[] args)
        {
            HttpWebResponse Response = null;
            try
            {
                string URL = "https://11.205.112.49:5311/Ping";
                Console.WriteLine("URL: [{0}].", URL);
                HttpWebRequest Request = (HttpWebRequest)WebRequest.Create(URL);
                X509Certificate2 Certificate = new X509Certificate2("F:\cert.pfx", "password");
                Request.ClientCertificates.Add(Certificate);
                Request.Method = "GET";
                Console.WriteLine("Sending request.");
                Response = (HttpWebResponse)Request.GetResponse();
                Console.WriteLine("Request sent.");
            }
            catch (WebException webException)
            {
                Console.WriteLine("Web exception occurred: [{0}].", webException.Message);
                Console.WriteLine(webException.StackTrace);
                Response = webException.Response as HttpWebResponse;
            }
            catch (Exception exception)
            {
                Console.WriteLine("Exception occurred: [{0}].", exception.Message);
                Console.WriteLine(exception.StackTrace);
            }
            Console.WriteLine("Response status code: [{0}].", Response.StatusCode);
            Console.WriteLine("Response \"Content-Type\" header value: [{0}].", Response.ContentType);
            Console.WriteLine("Response \"Content-Length\" header value: [{0}].", Response.ContentLength);
            String ResponseMessageBody = new StreamReader(Response.GetResponseStream()).ReadToEnd();
            Console.WriteLine("Response message body: [{0}].", ResponseMessageBody);
        }
    }
}

当它到达行 Request.GetResponse() 时，抛出 AccessVioationException：

问题是您缺少私钥。您只使用了证书。

要么在 loading certificate into X509Certificate2 class

时使用 pkcs#12

X509Certificate2 Certificate = new X509Certificate2("F:\cert.p12", "p12 password");

或load certificate from store

X509Store store = new X509Store("MY",StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);

X509Certificate2Collection collection = (X509Certificate2Collection)store.Certificates;
X509Certificate2 certificate = collection.Find(...)[0];
store.Close();
