What PGP / GPG encryption software is available for Windows?
(Answered by Daryl Houston, Jonathan Clark, Aaron Hazelton, Mike Heins and Michael Goldfarb) * PGP for various platforms: http://www.pgpi.org/products/pgp/versions/freeware/ * WinPT (Windows Privacy Tray) http://www.winpt.org A universal encrypt/decrypt program that operates generally via the clipboard so would be compatable with most programs, but there is also an Outlook Express plugin. It comes with GPG (below). * GPG Windows version http://www.gnupg.org/download.html * MIT distribution of PGP http://web.mit.edu/network/pgp.html Only for US and Canada for non-commercial use. There may also be an international version without those restrictions.
