Hello Peter and everybody,
I did some progress on this problem, but still have some issues. This is
what I did so far:
// obtain a collection of certificates
X509Store store = new X509Store("MY", StoreLocation.CurrentUser);
store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
collection = (X509Certificate2Collection)store.Certificates;
fcollection =
(X509Certificate2Collection)collection.Find(X509FindType.FindByTimeValid,
DateTime.Now, false);
// URL for my file to download
string myFile2Get = "https://www.MySecureWebsite.com/MyFile.txt";;
// create the specialized Web Request object
HttpWebRequest objHttpWebReq = WebRequest.Create(myFile2Get) as
HttpWebRequest;
// add the collection of the certificates
objHttpWebReq.ClientCertificates = fcollection;
// default method is GET
// get the response to my request
HttpWebResponse response = objHttpWebReq.GetResponse() as HttpWebResponse;
// Get the stream associated with the response.
Stream receiveStream = response.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
// Pipes the stream to a higher level stream reader with the required
encoding format.
StreamReader readStream = new StreamReader(receiveStream, encode);
Console.WriteLine("\r\nResponse stream received.");
Char[] read = new Char[256];
// Reads 256 characters at a time.
int count = readStream.Read(read, 0, 256);
Console.WriteLine("HTML...\r\n");
while (count > 0)
{
// Dumps the 256 characters on a string and displays the string to the
console.
String str = new String(read, 0, count);
Console.Write(str);
count = readStream.Read(read, 0, 256);
}
Console.WriteLine("");
// Releases the resources of the response.
response.Close();
// Releases the resources of the Stream.
readStream.Close();
There is no error thrown, but instead of getting the content of the text
file I am trying to read, all I get is message saying "Virtual user
'NameOfMyCertificate' is logged in". What am I doing wrong? How do I get to
read the file and not just some status message? Is this something that is
done in two steps: connect to the secure site and then request the file? If
so, what would be the sequence?
Any help will be highly appreciated.
All the best,
Eddie

Hi Eddie, I haven't done it; but (if you want to use WebClient) I believe
you'll have to specialize WebClient and override the GetWebRequest
method. If you've got an http[s] URL, the default should create an
HttpWebRequest object (you'll have to cast from the WebRequest return from
the base, i.e. call the base first), and HttpWebRequest has a
ClientCertificates collection property. You can add a
X509Certificate/X509Certificate2 object to this collection.
X509Certificate has lots of ways to load from file; or you can enumerate
those stored in a store via the X509Store class[1].
Let us know how that works out.
