Dear Notmuch Developers,

I have trouble getting going with S/MIME.

Emacs version: GNU Emacs 27.1 (build 1, x86_64-apple-darwin18.7.0, NS
appkit-1671.60 Version 10.14.6 (Build 18G95)) of 2020-08-12

notmuch version: notmuch 0.31+2~gd127b16
(brew install notmuch --head)

gpgsm version: gpgsm (GnuPG) 2.2.23
libgcrypt 1.8.6
libksba 1.4.0

When I send an encrypted and signed message to myself, the sending works
as expected.

When I open the message in emacs from a notmuch search, the gnupg
password agent pops up, and asks for the passphrase for my secret
key. Once the password agent dialogue is finished (I entered the
passphrase), emacs switches to a notmuch-show buffer with the
message. The body part of the message however only shows "[ smime.p7m:
application/pkcs7-mime ]", nothing else.

I then hit the "$" key twice to turn processing for cryptographic MIME
parts off, and on again. After the second "$", the gnupg password agent
comes up again. I enter the passphrase, and the following appears in the
notmuch-show buffer:

----------------------------- End Quote ------------------------------

The actual message content seems to have been decrypted ok (it shows up
as the text/plain part in the dumped function arguments). Also, I can
open the message without problems in the Apple Mail.app that ships with
macOS (shows the same decrypted content, and a good signature).


Many thanks and looking forward to your thoughts,

Hello again,

for what it's worth, and hoping that it helps track down the problem,
here is the elisp debugger backtrace for the situation I described
(hitting "$" twice):

I'm a bit at a loss how to investigate this, not using SMIME or macOS
myself. Could you try duplicating the problem with the notmuch test key
/ certificate? I've attached the test key and the ca from from the
notmuch source.

If you have the same behaviour with this key, then please share a
message encrypted to this key that manifests the problem for you
(probably as an attachement)

I think I managed to duplicate this problem; it does not seem to be
macOS specific. I'm not yet sure if there are multiple problems, or if the
error message and the need to toggle crypto processing are related.

As a workaround, try adding

(defalias 'notmuch-show-insert-part-application/pkcs7-mime
  #'notmuch-show-insert-part-multipart/encrypted)

To your notmuch-config.el (or init.el)

It's not perfect (the encryption status for S/MIME needs some new UI
code on the emacs end), but it's better than the status quo, as far as I
can tell.

I think this might be a deeper issue. Looking at the structure of

  test/corpora/protected-headers/smime-sign+enc.eml

it looks like there is an application/pkcs-7 part for the outer
container with an encstatus, and one inside that (with the same mime
type) with a sigstatus. So maybe the right thing is to just ignore
missing encstatus?

Hello David,

first of all, many thanks for not giving up on this one!

Conceptually, a typical s/mime message looks like this:
----------------------------------------------------------------------
Received:
From:
To:
Subject:
Date:
MIME-Version: 1.0
Content-Disposition: attachment; filename="smime.p7m"
Content-Type: application/x-pkcs7-mime; smime-type=enveloped-data;
name="smime.p7m"
[more headers (opt.)]
                              <empty line>
gibberish (the CMS)
----------------------------------------------------------------------

After decrypting the gibberish (CMS), you get a new mime tree structure,
in which the top-level entity can be a multipart/signed (most often), or
a message/rfc822 (sometimes), or something else (rarely seen) [1].

[1] https://tools.ietf.org/html/rfc8551

I.e. you decrypt, and further mime parts appear. No assumptions should
be made about the tree's structure. Quoting from [1]:

---------------------------- Begin Quote -----------------------------
3.1.  Preparing the MIME Entity for Signing, Enveloping, or Compressing

   S/MIME is used to secure MIME entities.  A MIME message is composed
   of a MIME header and a MIME body.  A body can consist of a single
   MIME entity or a tree of MIME entities (rooted with a multipart).
   S/MIME can be used to secure either a single MIME entity or a tree of
   MIME entities.  These entities can be in locations other than the
   root.  S/MIME can be applied multiple times to different entities in
   a single message. [...]
----------------------------- End Quote ------------------------------

After decrypting your "outer" container (the CMS), the result is a mime
tree, i.e. should start with "Content-Type:". Standard mime tree
processing should be applied (recursively).

The bodypart handler error message shows this "embedded (inner) mime
tree", and in my case the top-level entity is a multipart/signed. You
wrote "the outer container with an encstatus, and one inside that (with
the same mime type) with a sigstatus". So it seems that at that point
you have access to the root of the "inner tree" (multipart/signed, you
can access the sigstatus), but the content-type information is from the
"outer" container (the CMS) still. Perhaps the recursive mime re-parsing
after the decryption is not happening?


More new questions than answers...
