Posting styles and PGP integration?

WIBNI there was a way to tell gnus to automagically PGP/GPG/SMIME-sign
mails via a posting style?

I am well aware of the pgp-stuff in BBDB, but it doesn't seem to work,
and posting styles seem just like the cleaner way of doing it (Like, I
don't want to send PGP-signed news articles except to a few groups).

(setq gnus-posting-styles '(("mail.pgp-sign-required"
                                (body "<#part sign=pgpmime>"))))

Yes, that is exactly what I had in mind.
Thanks a lot.

Oh, darn. (-%

That's not quite it, for when I reply to a mail by quoting it (with F or
R), the <##part...> stuff is inserted _below_ the quotation, which is
not a Good Thing, IMHO. Is there a way to move this to the first line in
a message? With message-setup-hook, perhaps?

Multipart PGP sign/encrypt (was: Posting styles and PGP integration?)

Ok, this reminds me of something.  adding the MML part tag to sign or
encrypt only works on the /current/ part.  This is a problem.  It
should operate on the entire mail.  Lets see.

doing a:

<$multipart type=mixed sign=pgpmime>
...
<$/multipart>

*almost* does the trick.

As an example, here are some headers from a multipart email signed by
mutt (which, IMHO does a very good job with this type of thing):

These headers are in the real headers of the email message:
Content-Type: multipart/signed; micalg=pgp-sha1;
        protocol="application/pgp-signature"; boundary="Pd0ReVV5GZGQvF3a"
Content-Disposition: inline

The above headers are what gnus generates when you use the <$part
sign=pgpmime> format, in case you were curious.

Next, depending on whether or not there are multiple parts, mutt
inserts a multipart/mixed type, in which each part is saved.  If there
is only one part, it is just encoded and saved:

Content-Type: multipart/mixed; boundary="6c2NcOVqGQ03X4Wi"
Content-Disposition: inline

--or--

Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Content-Transfer-Encoding: quoted-printable

etc etc etc

*****************

Now, what the point is, that gnus doesn't necessarily do things wrong,
it just does them in a different way (and is not RFC compliant, I
think...it's hard to tell)  Gnus generates the correct headers for a
single part, but when you try to use the multipart signed you get the
wrong thing:

This is the only header in the main header section of the message:
Content-Type: multipart/mixed; boundary="=-=-="

...

next, there is a multipart/signed part:

Content-Type: multipart/signed; boundary="===-=-=";
        micalg=pgp-sha1; protocol="application/pgp-signature"

next, a multipart/mixed part:

Content-Type: multipart/mixed; boundary="==-=-="

which then finally contains each part.

Now, what I'd really like to do is this:

<$part sign=pgpmime>
<$multipart type=mixed>

foo bar
la la la

<$part ...> <--- included file, etc.
<$/multipart>
<$/part>

Of course, this doesn't work, since <$part> automatically closes when
it encounters the next <$part> or <$multipart>.

So, is there a way to get Gnus to do what I want it to do?

I know a little elisp, and I've looked through the source a little,
but I tried following the MML code and it's pretty involved.

If there's no solution, does someone have a pointer on where to start
in the mml code?

We could resurrect direct multipart/signed support, which reflects the
structure of the generated message more closely:

<$multipart type=signed method=pgp>
...
<$/multipart>

I still consider this the correct approach.  (The necessary hooks are
already there.)

Yes, this sounds like the best solution, and then to have
mml-secure-sign-pgpmime do the 'right' thing (either part or
multipart) depending on whether or not there are attachments present.

Where is the relevant code?

Darn indeed. That'll teach me to speak without testing. :?

(defun dp:add-signed-part-tag ()
  "Automatically add a signature tag to a message..."
  (save-excursion
    (message-goto-body)
    (insert "<#part sign=pgpmime>\n\n")))
(add-hook 'message-setup-hook 'dp:add-signed-part-tag)

That should do it, modulo testing. :)

i'm having a similar problem with a similar setup.  what i'd like to do is
make sure to encrypt replies to encrypted mails (it's far too easy to SW,
type your reply, and C-cC-c while forgetting to M-mcp first).

what i tried was:
(setq  gnus-posting-styles '((header "content-type" "encrypted"
                                     (body "<##part encrypt=pgpmime>"))))

this almost works, but i get the same result as you, the encrypt tag comes
after the yanked text.  mucking with message-setup-hook doesn't seem to
help either because a) that's what gnus-posting-styles does, and 2) that
hook seems to get run *before* the yanked text gets inserted.  is there
any hook that gets run *after* the yanking?  hmm, maybe
gnus-message-setup-hook?

ok, what about this:
(setq  gnus-posting-styles 
        '((header "content-type" "encrypted"
           (eval (save-excursion 
                   (make-local-variable 'gnus-message-setup-hook)
                   (add-hook 'gnus-message-setup-hook
                    `(lambda ()
                       (save-excursion
                         (message-goto-body)
                         (insert "<##part encrypt=pgpmime>\n\n")))))))))

this seems to do *almost* what i want, with the odd side effect of putting
the encrypt tag at the top of *every* message.  even just hitting m in the
group buffer.  ugh, back to the drawing board i suppose...

Right. I'd really love to be able to set some variables from a
posting-style (just like you tried), so that message-setup-hook (or
similar, I don't want to look up their names) behaviour can be
controlled by posting-styles.

Is it time for gnus-posting-styles-fancy yet? (-:
