Requirement For User To Sign Some ASPX Forms With (Local) Certificate

Nov 28, 2012 2 or 4.0

We have a controlled list of the users (It s an Extranet solutions for our collaborators)

We need to develop some new web pages (not all) some of which require the user accessing the web page to fill out some form and sign it using his digital signature/certificate. Each customer has their own certificate which he has on his computer (either as a local desktop file or the certificate may be probably integrated into the browser certificates via browser advanced options).

In other words:

1- Allow a client visiting some of the web pages to digitally sign the form before submitting it to our web server (the signature is his specific certificate)

2- Send either the form and the certificate or the html encrypted with his certificate to the web server

3- Read and identify the certificate on the web server (C# code)

Sign Data In ASPX On Client Side?

Dec 20, 2010

In my application, the client must sign (using a certificate) and send data to the server.My doubt is how should I do it?

To sign on the client side, I should use ActiveX right? My problem is that firefox doesn't support it.

Signing on the server side I have two options:

Save the private key on the server and use it when necessary (if the data is modified during the transaction it will sign false data)Send the private key when necessary (may comprise the key)

Despite using SSL, I'm not very confortable with any of the two options for signing on the server side...

Post Client Certificate From IE And Validate Certificate On IIS / Web Server

Nov 30, 2012

Let's assume our users in their office using Internet explorer to sign some Web Pages using their client certificate imported into the Internet explorer browser (let s assume no other browser is used)

what is a good approach/architecture for validating the client certificate (Internet Explorer), how to send that certificate or the signed form to the server and how do we verify the signature

Should we use smart client approach integrated to the web application or some silverlight or so or is web form/web pages enough to implement this security requirement ?

After configuring the application like I've always done on Server 2003, I keep getting the following error when attempting to access the page:

Exception Details: System.Exception: Unable to open certificate. IWAM_plesk(default) subject: Email Certificate

I have installed the certificate service and it's running... I have granted the IWAM user every possible permission, including making it a member of the Admin group, but still getting the same error.

Sign Out Button Reloads All User Controls?

Apr 16, 2010

I have an aspx page with several user controls (ascx) as well as an asp:button for signing out.

The click event of the button clears the session and does a response.redirect to the login page.

However, before the click event is called, since the page posts back, all of the Page_Load events run for all of the controls.

What is the best way to have the click event code run without unnecessary reloading of all user controls?

Web Forms :: A Centralized Web App That Uses A User's Local Connection String?

Jul 24, 2010

I am writing a web app for work. The users who are using this app will not be using the same connection string- for example, we have about 40 customers whose data resides in their respective database. The goal of this app is to be able to query the database for a given customer without having to go in and modify the web.config connection string (obviously, because that will change the connection string globally across users- I want the users to be able to have their own local connection string to be used by the app). is this possible?
