How can I get the X509Certificate sent from the client in web service?

I am trying to get client certificate in web service.

  1. I add client certificate in proxy object and call web method Verify.

    private void button2_Click(object sender, EventArgs e)
{
    string certPath = "D:\\test.pfx";
    cert = new X509Certificate2(certPath,"pass");
    Service1 obj = new Service1();
    obj.ClientCertificates.Add(cert);
    textBox2.Text = obj.Verify();
}

Web Method in Web Service:

[WebMethod]
public string Verify()
{
    X509Certificate2 cert = new X509Certificate2(Context.Request.ClientCertificate.Certificate);
    bool test = cert.Verify();
    return test.ToString();

}

In finish with this error:

System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Security.Cryptography.CryptographicException: m_safeCertContext is an invalid handle.

I don't know why. I used this sample.

I test web service and client on localhost.

Have you tried to follow this guide?

  • Host the project from IIS - not the thin web server that is bundled with VS2005.
    • From within VS2005 select File - New Web Site.
    • Select the Location of HTTP then enter the path eg: http://localhost/MyWebSite. Note that you don't have to use HTTPS just yet (I find it easier for development to use HTTP then when deploying to UAT or Production to use HTTPS).
  • Code up a test form.
  • Go into IIS Admin - right click on the new app (MyWebSite) and select Properties.
  • On the Directory Security tab, click Edit... under 'Secure communications'.
  • Make sure 'Accept client certificates' is checked.
  • When you run your app - make sure you use HTTPS in the url eg: https://localhost/MyWebSite
