CY>Buzzword alert. What is "TPU"? And who makes "Async Pro", and what CY>exactly does that do? Well, in the PC world, a TPU is just a Turbo Pascal Unit. It's become kind of a standard for making easy add-ons to programs since a lot of programmers use Turbo Pascal. Async Pro is written by Turbo Power software. Anyways, does anyone have any basic ideas on what functions would be really important for some kind of programmers toolkit? To narrow things down you might want to make a PGP toolkit that manipulates PGP keys and makes using PGP easier from other programs. So, does anyone have feedback on some good general PGP encrypted file manipulation functions? Once you make them easy to integrate into other programs I'm sure more and more people will pick it up. Reading through the vast amounts of C code on PGP is quite a daunting task.
