[RFC please] new RFC3156 patch for balsa2

[Albrecht Dreß <albrecht dress arcor de>]

Hi all,

here is a new patch for balsa2's support of RFC3156 (pgp/gnupg) 
signed/encrypted messages. It is possible to send and receive signed, 
encrypted and signed and encrypted single and multipart messages with 
balsa. I now work for some time with the patch (well, about a week ;-)), 
and it seems to be stable. Exchanging messages with sylpheed works fine, 
but I could not check other mua's yet.

I think I implemented all the necessary low-level framework (a lot of it 
will be removed when balsa moves to gmime), but the UI still has lots of 
rough edges. Basically, there are two more menu checkboxes to enable 
signing/encryption. Signatures in received messages (including embedded 
signatures, e.g. in forwarded message/rfc822 parts) are checked 
automagically, and the application/pgp-signature is replaced by a 
descriptive text with a few more information.

I think I should add that Laurent Cheylus works on a patch to support 
RFC2440 for balsa 1.4.2. IMHO it would be great if we could join the 
patches and offer support for both '2440 and '3156 for the 1.4 and the 2 
series of balsa.

As the patch is quite large, I submitted it to bugzilla (you will also 
find a description, installation instructions and a todo list...):

http://bugzilla.gnome.org/show_bug.cgi?id=107756

It would be really great if some people could test it and mail me their 
experiences, good or bad. Any comment is really welcome! Be warned, 
however, that it may have mem leaks, make balsa crash, degrade your karma, 
or upset your friends in domestic intelligence...

Hope you like it (and *please* tell me why if not!),
Cheers,

Albrecht.
