Security and Signatures
Clink, open cell-block 4! PDF supports all manner of different security-based functionality from "permissions" that as an application developer, you're supposed to support -- to a range of low to high-end type encryption technology which prevents the average Joe doing anything untoward with your documents. One of the great new additions here is our DigSig support. You can use this to make sure that once you've created your document, you can make sure that if someone does change it -- that it's clear and obvious to any future reader.
