Note to all users

This page is no longer updated, since the original purpose of the page has been nullified by more recent versions of PGP and GnuPG. I'll keep it up as a reference, but I don't have much interest in updating it. Thank you for visiting my site, and thanks to everyone who contributed - a HUGE list.


PGP & Mail Clients

Trying to get started with PGP? Trying to get a friend started with PGP? Switching e-mail clients? Then check out this page to find out about the various PGP plugins available for many different e-mail clients! This is an extensive list, but there are always e-mail clients and plugins we don't know about. (9/26/06 - this list is severely out of date, I know. I'm not interested in maintaining it, especially since I didn't write it in the first place.)

Current Versions (out of date):


*NEW*

(5/6/2003) GnuPG has released GnuPG 1.2.2.

(12/7/2002) PGP has released PGP 8.0. Sweet!

(10/27/2002) A bugfix release of GnuPG is available.

(10/3/2002) Okay, it's been a really long time. I'm finding that the main purpose of this page (clearing up confusion between version 5 and version 2.x compatibilities) has definitely decreased in importance, so I'm lax about updating it. Anyway, we have the newly formed PGP Corporation talking about releasing PGP Corporate Security 8.0. The folks over at GnuPG haven't been idle, either, with their recent release of GnuPG 1.2.0.

(5/3/2002) Long time no update. Sorry about that, other projects have been keeping me busy, plus there hasn't been many new version of PGP/GPG released. Anyway, GnuPG 1.0.7 is now available and it supports RSA key generation! This is especially good to hear since NAI may not be producing new versions of PGP.

I've been getting a lot of e-mail regarding PGP and Windows XP. I'm not a good person to ask since I don't use Windows XP, but here is a link to a FAQ on the issue: Tom McCune's PGP Questions and Answers.


This page is dedicated to demonstrating which versions of PGP will handle RSA, DH, or both types of keys.

Any additions, subtractions, or corrections should be e-mailed to pgp@rjmarq.org. Thank you! For encrypted messages, here are my DSS/DH key block and RSA key block.

Errors in this page are almost definitely mine; I never realized how complicated this was until people started feeding me info! In fact, there was so much info contributed by everyone that I stopped listing what each person sent me, since it was getting too long.
