The environment is a Windows domain. Windows Server 2003 is the controller and all clients are running WinXP or better. Office 2003 (2007 soon) is used to create most documents.
What I'm looking for is a way to electronically sign documents. Self-certification, I believe, would be fine.
I guess I really don't know anything about this and am having trouble finding a starting point. In my perfect scenario, when I create a user in the system a digital signature (cert, or whatever) would also be created, which could then be used by the new user to sign documents with as little trouble as possible.
Can someone educate me a bit here? What do I need to learn, and where can I learn it?
