Topic: Digitally Sign PDFs with a Program/Web Site

I'm creating a web site that will be dynamically creating PDF files and emailing them to the users. Because the PDF files could be misused, I need to digitally sign the files to ensure they haven't been altered.

Acrobat 5 can sign the documents, but requires a human to run Acrobat to do the signing. I'm looking for a way to automate this process for the web site. I'd like the site the be able to do all of the steps of creating and signing the document automatically. I have a tool to create the document dynamically; its the signing that's the problem. Does anyone have any familiarity with a tool to do this? A 3rd party tool is fine. Either a command line interface or programming interface would be fine. The environment is not yet defined and the site may be written in ASP or possibly JSP pages.

Any help is greatly appreciated.

Thanks.
