INTRODUCTION
Apple has integrated commercial grade digital signatures into the operating
system as part of System 7 Pro. Specifically, DigiSign is a component of PowerTalk,
the client software portion of AOCE (Apple’s Open Collaboration Environment).
DigiSign is comprised of three parts; the Digital Signature Manager and API, Drag and
Drop signing in the Finder, and the DigiSign Utility. In this article we will
concentrate on the Digital Signature Manager though there may be some references to
the other parts to fill things in.
