Custom SSL certificates

[wyattbiker]

I dont know how to search for something like this, but here is what I like to do:

I have an internet accessible LAMP application that uses HTTPS: The user must login to access it.

I would like to make it so that each authenticated user can only access it from authorized workstations.

Is there a way to create a certificate that only is valid from the workstation or mobile device it was created on?

Maybe it can be based on a hardware serial # or something else specific to that machine.

Any docs that explain how to do this?
