Re: Web Service Protection with Client Certificates

17-Feb-10 3:55

Trying to protect a web service by reading a client certificate in order to validate the client but all of the articles I've Googled are connecting to a web service with a client certificate.

Does anyone know of an article or book that has an example of creating a web service that verifies a client certificate and denies all non-validated requests?

In IIS enable accept client-side certificates. You can then map the certificates to Windows logins through IIS and use Windows Role Based Security.

In II6 click the properties for your web service, click directory security, in secure communications click edit, check enable client certificate mapping, click edit, map users.

Have IIS configured and calling the web service with the following code:

string cert_path = @"C:\cert.cer";
web_service.ClientCertificates.Add(X509Certificate.CreateFromCertFile(cert_path));

How do I verify that the client certificate sent is valid on the web service?

Follwed this tutorial and still can't get the certificate authenticated. Returns 403 error.

Even tried mapping the certificate to administrator with the same result. Mad | :mad:

Self-signed certificates are rejected by ASP.NET by default since they are not valid.

Author your own validation[^]

I am using a client certificate that was provided by a well known CA. Even when trying to access the site with IE (with the client certificate installed in the Other tab) I get the 403 error, requires client certificate.

I am facing an issue in gridview control(asp.Net,c#), see below code panel

<asp:TemplateField HeaderText="Action">
                       <ItemTemplate>


                                       <asp:ImageButton ID="imgLiveTest" CommandName="<%#DataBinder.Eval(Container.DataItem,"type")%>"
                                           ImageUrl='<%# GetImageTestLive(DataBinder.Eval(Container.DataItem,"liveServer")) %>'
                                           OnClick="imgLiveTest_click" runat="server" />

                                       <asp:ImageButton ID="Edit" CommandName="<%#DataBinder.Eval(Container.DataItem,"type")%>"
                                           OnClick="Edit_click" ImageUrl="images/edit.gif" runat="server" />

                                       <asp:ImageButton ID="Delete" CommandName="<%#DataBinder.Eval(Container.DataItem,"type")%>"
                                           OnClick="delete_click" ImageUrl="images/cancel.gif" runat="server" />

                       </ItemTemplate>
                   </asp:TemplateField>

Just right click on the image control (which is rendered as no image) and see if the path that its src has can be accessible by directly putting in the browser.

You need to have access previledge to a path from the client to see the image.

Also why do you use :
ImageUrl='<%# GetImageTestLive(DataBinder.Eval(Container.DataItem,"liveServer")) %>'

single quote here while using double quote for all others. D'Oh! | :doh:

As a file is just a collection of data, and an image is just a collection of data how would you know if any data is an image?

You can Search for "<img" tag using regular expression:

<img[^<>]+>

Well thats rather different from what you first asked about. In this case, you can use a regular expression to find the img tag, or split the string in various ways.

Well, have you used the tried and trusted method of MSDN or Google? I am not in the business of writing free code, I have told you the method(s) you can use, its up to you to make an effort and research them. Both regular expressions and string manipulation are pretty basic subjects, if you want to be a developer you need to learn to think for yourself.

If you have a specific problem, post the code and error message and someone will help you.

Also, please use all the keys, don't write in text speak, its just plain stupid.

Retrieving the COM class factory for component with CLSID

17-Feb-10 23:30

I assumed that by telling you which methods to use I was helping. If this is your attitude then I will not bother helping any further, you ungrateful b*gger.

My point about text speak is simple really. Many people who use Code Project do not have English as their first language, and its often hard enough to figure out what they mean when they use full words without havng to try and guess what word they meant from 2 or 3 letters.
