Subject: org-crypt fails if default key is expired while non-default key is to be used
Date: Sun, 22 Jan 2023 18:41:23 +0100	[thread overview]
Message-ID: <2023-01-22T18-32-17@devnull.Karl-Voit.at> (raw)


I think I've found a bug with org-crypt:

Org mode version 9.5.5 (release_9.5.5 @

GNU Emacs 28.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33,
cairo version 1.16.0) of 2023-01-09


org-crypt fails to encrypt when org-encrypt-entry is set to a
different key than the default openpgp key and the default key is


My setup involves an openpgp-key which is specifically used for
org-crypt. This key is not my default key A1234567 which I'm using
for encrypting and singing emails and such.

org-crypt-key is set to this secondary key, let's call it
org-openpgp-key. So the org-crypt setup is correct in that sense
that org-mode should not care about other keys than my

However, I've had the situation where the default openpgp key
expired on a machine. Please note that my org-openpgp-key did not

When I invoked org-decrypt-entry, decrypting works like always. Then
I modified something in this heading which is tagged with :crypt:.
On saving that buffer, org-crypt issues an error message:

| Error: (error "GPG error: \"Encrypt failed\", \"Unusable public key:
| A1234567; Exit\"")

This A1234567 key is my default key and not the org-openpgp-key.

org-encrypt-entry is causing this error at:

|	;; Text and key have to be identical, otherwise we
|	;; re-crypt.
|	(if (and (equal crypt-key key)
|		 (string= checksum (sha1 contents)))
|	    (get-text-property 0 'org-crypt-text contents)
|	  (epg-encrypt-string epg-context contents crypt-key)))

After fixing the expiry date of A1234567, org-crypt was working
properly, using the correct org-openpgp-key again.

I do think this is wrong behavior: when the default key is expired
but a specific secondary key is used, encryption should be possible.
