Can't connect to HTTPS using X509 client certificate
- by wows
Hi - I'm new to cryptography and I'm a bit stuck:
I'm trying to connect (from my development environment) to a web service using HTTPS. The web service requires a client certificate - which I think I've installed correctly.
They have supplied me with a .PFX file. In Windows 7, I double clicked the file to install it into my Current User - Personal certificate store.
I then exported a X509 Base-64 encoded .cer file from the certificate entry in the store. It didn't have a private key associate with it.
Then, in my app, I'm attempting to connect to the service like this:
var certificate = X509Certificate.CreateFromCertFile("xyz.cer"));
var serviceUrl = "https://xyz";
var request = (HttpWebRequest) WebRequest.Create(serviceUrl);
request.ClientCertificates.Add(certificate);
request.Method = WebRequestMethods.Http.Post;
request.ContentType = "application/x-www-form-urlencoded";
I get a 502 Connection failed when I connect.
Is there anything you can see wrong with this method? Our production environment seems to work with a similar configuration, but it's running Windows Server 2003.
Thanks!
