Just in case anyone is interested, gpg 0.32 (I think...) is implemented in
pgp4pine, a program allows pine users to interactively sign/encrypt their
messages, and decrypt their incoming ones for pine (3.95 and 4.0 known to
work). It supports gpg, pgp2, and pgp5 (although if you NEED to read the
README file). It's at http://www.netcom.com/~wiegand/chris/pgpmail_en.html

It was my patch, which removed it. Original exmh-2.0.2 comes with the old
PGP...
You're the second person, who asks me about where the old PGP.. menu
disappeared.
I thought, it doesn't offer any things, that the "newer" PGP support doesn't.
I tested it out. I was wrong. People may want the behaviour of the old PGP...
further on including the decryption
and *storing decrypted*. With the "newer" implementation you need to decrypt
encryted messages every time
you look at them.

I made few changes to the PGP5 and GPG patches:
I reincluded the old PGP... menu slightly changed. It should behave as in
original exmh-2.0.2. It doesn't support
either PGP5 or GPG. If you want to update old PGP... to the new versions, take
a look into app-defaults and pgp.tcl at procs Pgp_View and Pgp_Decrypt, which
are called from the menu. I didn't update them to multiversion, because I
think there are buttons and menus enough.

You're right.

Ugh, sounds horrible.
Hm, the expectk parts of the PGP support never worked for me. I don't know
why, but I didn't get them running.
I left the PgpDecryptExpect script untouched at all. I looked at it, but I
didn't recognize, that Misc_GetPass is called without version parameter. With
pgp as parameter, things should work as before.
The new patches I've made, should work with pgp2.6 as the original support did.

BTW Don't forget to enable debug logging in Preferences with the patches
applied.

I never used the expectk stuff. The DecryptExpect stuff should have caused the
problems, you reported.
People reported me, that the PGP2-PGP5 double version patch works fine for
them (they obviously never used expect).

I have all three supported versions installed at home: PGP2.6.3i, PGP5.0i and
GnuPG 0.3.4. I use my three version patch. I hadn't the chance to test GnuPG
support very much, because there aren't much people who use it,
but PGP2.6 and PGP5.0 work fine for me, no problems.

Few things aren't supported by exmh-GnuPG:
-- Keyservers (use key attachement!)
Hm, there aren't GnuPG keyservers yet, are?
-- DSA/ELG keys, because there is a problem in specifying the keyid, when
encrypting(/signing).

I get a fault, when specifying the DSA id with -r.
I've got a DSA/ELG pubkey (pair):
pub 1024D/DE5E7FB2 1998-08-18 Markus Gruber (DSA/ELG)
<markus.gruber@ilo.baynet.de>
sub 2048g/89D46141 1998-08-18

GPG doesn't accept the DSA keyid specified, when encrypting/signing (like exmh
does)...

Werner Koch is in vacation for three weeks. I cannot ask him.

ELG and ELG-v3 keys work fine with exmh.

If you want to retry:
Reload the patches, they contain the fixes I described and few minor ones.
Don't forget to uninstall the "old" one(s) before installing the updated patch.

Hoping you've more fun now,
