title: Digitally sign using client certificate in ASP.Net
body: <p>I am trying to digitally sign information with a private key.  I know how to do this on in a desktop client application with .Net, but am not sure how to do it in ASP.Net.  It would be used on an intranet using IE8.  If it is done via ASP.Net, I am guessing that the private key is not sent to the server when the user types in their certificate passowrd when going to the site (https, 2-way SSL), but am not sure.  If there is no way to access the client private key on the server, then how can I sign something in the browser?  Can I use javascript?</p>
  
  <p>Edit: I guess what would be helpful to know first is if this can be done on the server or does it have to be done on the client?</p>
