Here is the scenario friends,

I have an html page which I load it on a server. I give the URL of this page to my clients. My clients have their digital certificate in their web browsers. There is some data on the html page which is filled by the clients. When the client hits the submit button, a java script should run from behind which should be able to pick up the digital certificate of the client which is laoded on their web browser. This information must be sent along with the data to the server. Is it possible to do this using Java script? Can we access Certificates on a system via Java script? Are there any API calls which can be used in Java script for this purpose?

Any help will be appreciated.

Thank you for your time.
