19.3. 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:
* WinPT (Windows Privacy Tray)
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
* MIT distribution of PGP
Only for US and Canada for non-commercial use. There may also be an international version without those restrictions.
