I ran the debugging programme with Openpgp debugging options to console and I got the
message that with gpg2 installed one was not able to digitally sign an e-mail whilst
encrypting to their public key which in all the named distros it encrypted to my private
key - fact.
Another user who was using Fedora-16 64 bit with gnome stated that Openpgp would not
initialise pgp2 - and me? I ran Fedora-16 32 bit - I had to reboot before openpgp would work
(so badly as was useless) with gpg2. Fact I even when and installed Fedora-16 64 bit fact
and encountered the same issues, Fact.
It is a fact that Openpgp will only work if BOTH gpg 1.4.11 and the widget gpg2 is then
added. Fact. Most Linux users have BOTH by default. Fact. That's why no one's reporting aany
problems. Fact. If you remove from your system gpg 1.4.11 then you have real problems with
open Openpgp - even Kleopatra. Fact
Now if you don't like these facts then that's not a problem. I have decided to tell every
one not to use gpg2 without having installed gpg 1.4.11. Now as I haave spent the last 10
days playing with all these Linux distros and sending all these test e-mails which have
provided factual evidence as stated I can only conclude that Openpgp will only work with
1.4.11 installed. Now I have not mentioned anything about Windows XP and the latest version
of PGP4Win which some times encrypts to my girlfriends private and not to my public key I've
not figured out that one yet - unless I install gpg 1.4.11!!
I will say this I am running Linux Mint LXDE 32 bit - on a 64 bit Acer Laptop with all
updates. My gpg-agent's running because I added it to my .xsession file. Now I have
un-ticked the box - use agent. Now Openpgp is pretty variable in how long my passphrase
lasts - it could last all day yet it could last to the next e-mail.
But I don't trust Openpgp to honour per-recipient rules. It does not work ie it will not
encrypt to the e-mail address as set out in its own rule. Fact.
Now if you can't even trust the software to do what it says on the tin - then you have to
go back to basics as I have done. Fact.
Now I have pointed out some serious short comings that are spread over Linux Distros and
Windows XP with Thunderbird and enigmail/Openpgp installed. Fact.
I am not angry - far from it - I got a lot of brain ache burning DVDs installing various
Linux Distros and playing with them. I would have tested more - but hey - I pointed out the
facts of my discovery. Now all my 3 Linux laptops are Mint Linux LXDE 32 bit installed with
TB gpg 1.4.11 enigmail/Openpgp - No probs. Fact. But I still do not trust enigmail/openpgp
to do anything on the tin. Fact.
Now on the whole as no one's interested in these facts - I don't much care. I worry about
sending an encrypted mail to some one's public key in case it does not work. It digitally
signs e-mails - but I have no confidence no assurance of encrypting to a public key. My
girlfriend who only sends me encrypted mail sometimes sends me encrypted mail that I cannot
read. Why? The answer is very very simple - sometimes Openpgp/enigmail signs to your
private key and not the person your e-mailing's public key. Fact. I'm not angry about that -
why? Because the error does not happen all the time. Fact.
All I do is repeat the facts. Get 50 variants of popular Linux distros KDE/Gnome?LXDE do not
install gpg 1.4.11 just gpg2 TB Enigmail/Openpgp and have fun.
