cross-link for GnuPG T4354: dirmngr should send "fingerprint=on" to keyservers

Reported by steve | January 30th, 2019 @ 11:12 AM | in 2.2.17 (closed)


Currently Some keyservers do not behave like others when it gets to listing keys with fingerprints.

dirmngr currently doesn't add "fingerprint=on", nor has it an options to set it manually for a request.

Expected Most servers return a list including fingerprints, but some only respond with key-ids.

This can be reproduced using the following request:

When "fingerprint=on" is added to the request, all tested keyservers return the fingerprints – which would be preferable.

Here are two keyservers to test, which are both part of the sks-keyservers.net pool:
"normal" behavior:        pgpkeys.uk ( sends key-id be default:  pgpkeys.hu (

Here is the required patch for dirmngr (patch by mento@gpgtools.org):

Thanks for considering adding this.

    Kristian responded in gnupg tracker: "So, the keyserver operator had thrown in a hockeypuck server in the pool, causing this.. While the keyserver remains in the exclude list until confirmation it has been resolved, that explains the behavior and it has been made clear that separate software needs to use different names in the future. In any case, marking this resolved"
