Notes digital signature vs. Verisign digital signature

I’m using a controlled access section in a form with at least 1 “sign if mailed or saved field”. Everything works fine with the designer/notes signature. Now our client want us to use Verisign. Can I use Verisign to digitally sign a Notes application for a Notes client, if so how? There is no e-mail, internet or encryption involved here.

Thanks for any direction.

If this is a Client application has the client indicated why they want to use Verisign instead of built in functionality?

I’m guessing it has to do with security in name recognition.
