Subject: [PATCH] Use S/MIME key from content for mail signing via OpenSSL
Date: Wed, 20 Dec 2023 14:16:56 +0100

[Message part 1 (text/plain, inline)]

* Bug

mml-smime-openssl-sign always takes the cdar of smime-keys, resulting in
keyfile parameter of the #secure tag being ignored.  Hence, only the
first entry of smime-keys is used, regardless of the mail contents or
sender address.

* Fix

The relevant information (returned from mml-smime-openssl-sign-query) is
already in the cont alist passed to mml-smime-openssl-sign, just use
that instead.

* lisp/gnus/mml-smime.el (mml-smime-openssl-sign): Use the key
passed in the cont argument instead of the first smime-keys entry.
