Authenticating via smart card in .NET:
//Create new X509 store from local certificate store. X509Store store = new X509Store("MY", StoreLocation.CurrentUser); store.Open(OpenFlags.OpenExistingOnly | OpenFlags.ReadWrite); //Output store information. Console.WriteLine ("Store Information"); Console.WriteLine ("Number of certificates in the store: {0}", store.Certificates.Count); Console.WriteLine ("Store location: {0}", store.Location); Console.WriteLine ("Store name: {0} {1}", store.Name, Environment.NewLine); //Put certificates from the store into a collection so user can select one. X509Certificate2Collection fcollection = (X509Certificate2Collection)store.Certificates; X509Certificate2Collection collection = X509Certificate2UI.SelectFromCollection(fcollection, "Select an X509 Certificate", "Choose a certificate to examine.", X509SelectionFlag.SingleSelection); X509Certificate2 certificate = collection[0]; X509Certificate2UI.DisplayCertificate(certificate);
After this, you can use the cert however you want :_
