S/MIME + additional certificate files

[beaker@iavmb.pl (Krzysztof Jędruczyk)]

Hello,

I've recently tried to send some S/MIME signed messages and
encountered a problem, which I believe lies in gnus' smime.el. The
problem is that even if I specify additional certificate files in
smime-keys variable - they don't get attached to signature. This
might cause with verification - depending on what certs recipient
has already installed (the certification path will be incomplete).

I've searched google for reports on this particular problem, and found
nothing. So - I looked at it myself. 

I identified the problem to be in smime-sign-buffer, which in turn
passes keyfile retrieved with smime-get-key-by-email to
smime-sign-region. The problem is that smime-get-key-by-email returns
only the key without accompanying additional certs.

Workaround that works for me is to change line 315 in smime.el from

       (smime-get-key-by-email
to
       (smime-get-key-with-certs-by-email

and add new function definition:

(defun smime-get-key-with-certs-by-email (email)
  (cdr (assoc email smime-keys)))

I believe that this is incomplete solution - I haven't reviewed if
rest of the code doesn't suffer from similar problem. I'm just
signaling a problem here since I know elisp very little.

BTW. I'm using an Oort Gnus, (AFAIR 0.08; it should be mentioned in
the headers of this message), taken from cvs about 28-aug-2002.
