How to digitally sign PDF documents in a web application?

I'm building a web application that most allow the user to digitally sign PDF documents with certificates installed in the client machine.

The document, once signed, should be posted back to the server, where it will store the signed version.

The server is running Classic ASP/ASP.NET

Where should I go?

Now you can sign PDF documents right from your Chrome Browser Preview Page. Simply click on the „Sign“ icon that appears in the lower right corner of your PDF Preview to sign any PDF document without leaving the page.
