Automatically add trusted publisher to client store


I want to download pfx from my asp.net server, add the pfx to client's
X509Store as
a trusted publisher, Is it possible? my func in aspx is like this:

void InstallCertification()
{
try{
WebClient web = new WebClient();
string url = "http:/myaspserver/mydir/mykey_2008.pfx";
byte [] b = web.DownloadData(url);
X509Certificate2 cert = new X509Certificate2(b, "password");
X509Store store = new X509Store(StoreName.AuthRoot,
StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadWrite);
store.Add(cert);
store.Close();
store = new X509Store(StoreName.TrustedPublisher,
StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadWrite);
store.Add(cert);
store.Close();
msg.Text = "Certification installed";
}
catch(Exception e)
{
//MessageBox( e.ToString());
msg.Text = e.ToString();
}

but the page will load pretty much longer time and show the error of
System.net.webexception that unable to connect to remote server
(Actually myaspserver is working, the aspx and the pfx url is correct).

Best Regards
Steven

where is this code running? if its in the codebehind, then the server is
downloading a cert from itself, and trying to install it to itself. if this
is what you are trying to do, then try localhost, so thats it a loopback, as
it common to have outgoing port 80 blocked on a webserver.

Hi Steven,

If you put a txt file in the same virtual directory where the pfx file
locates and access it in the browser via http://myaspserver/mydir/test.txt
can you see the content of the file? If you can, can you download it via
the following code?

WebClient web = new WebClient();
string url = "http://myaspserver/mydir/test.txt";
byte[] b = web.DownloadData(url);

If you can from your description the following code does not work? (Please
confirm it)

WebClient web = new WebClient();
string url = "http://myaspserver/mydir/ mykey_2008.pfx";
byte[] b = web.DownloadData(url);

Please test it and tell me the result. It can help to narrow down this
issue. BTW, does your client machine need a proxy to access network
resources? In addition please check the Firewall settings on both server
side and client side as Bruce mentioned.

Allen Chen

If WPF testapp work, in general aspx shall work, both of them call .net
am I right? but it seems that the aspx would not work.

Hi Steven,

I remember the proxy detection of ASP.NET applications is different from
that of desktop applications. Could you try to explicitly specify the proxy
to see if it works?
WebClient web = new WebClient();
web.Proxy = WebProxy.GetDefaultProxy();
string url = "http://myaspserver/mydir/ mykey_2008.pfx";
byte[] b = web.DownloadData(url);

Hi Allen,
Sorry that I didn't response this due to busy on other stuff. I tried
updated the
aspx page and added Proxy = WebProxy.GetDefaultProxy(), when I visit this
page
from client side (I called the InstallCertification in the Page_Load), the
browser says that:

System.Net.Sockets.SocketException: No connection could be made because the
target machine actively refused it 127.0.0.1:8080 at

Hi Steven,

Thanks for your update.

Are you accessing the 80 port or the 8080 port? From the code you provided
previously you're accessing the 80 port. See below:

WebClient web = new WebClient();
string url = "http://myaspserver/mydir/test.txt";
byte[] b = web.DownloadData(url);

However, from the exception it seems you're using this url:
string url = "http://myaspserver:8080/mydir/test.txt";

Could you clarify which url you're using? If it is 8080 please check if the
TCP port of this site has been set as 8080 in IIS.
http://support.microsoft.com/kb/149605

For further investigation please also provide the IIS version and the
operating system you're using.

Hello Allen,
I tried to update the path and no file download issue anymore, but the
trust
will not be added to the client computer and it shows that X509 cannot be
applied.
It looks like the code download the prx file from itself and then try to add
the trust
to the server computer, not the client computer.
You know the aspx is the server side code, Is there any way to modify
the
code let:
When client computer visit this aspx page,
this aspx page download the prx to the client system and install it into
the client computer?

Best Regards
Steven

Hi Steven,

Firstly, for the security reason, automatically downloading and adding the
pfx to the X509Store is not recommended.

If we have to do so we need to use ActiveX. However, we cannot ensure if
the clients have enabled ActiveX. If they don't we cannot achieve the
requirement.

Following article demonstrates how to create an MFC ActiveX control:

http://www.codeproject.com/KB/COM/CompleteActiveX.aspx

Another option is to let your customer download a console application and
run it. You can put your code in the console application. Then add a
download link on the page to notify your customers. Though it's not an
ideal means I think it's a more secure way for your customers.

Please let me know if you need further assistance.

Allen Chen
