Hello,

another question: how do I find the key id in mutt's (gpgme's?)
information for signed mails? For my previous mail mutt shows me this:

> [-- Begin signature information --]
> Good signature from: 1.2.840.113549.1.9.1=3D#726F626572742E6A61657363686B=
654068752D6265726C696E2E6465,CN=3DRobert
> Jaeschke,2.5.4.42=3D#526F62657274,2.5.4.4=3D#4A61657363686B65,2.5.4.97=3D=
#474F5644452B4245,O=3DHumboldt-Universitaet zu Berlin,ST=3DBerlin,C=3DDE
>                 aka: <[email protected]>
>             created: Wed Jul  1 10:36:10 2026
> [-- End signature information --]

If I check that mail's signature manually using gpgsm,=C2=B9 I get the
following output:

> gpgsm: Signature made 2026-07-01 08:36:10 UTC
> gpgsm:                using rsa2048 key E476ADAA614A7E1CFDC3D5D17F378D998=
076E616
> gpgsm: Good signature from "/CN=3DRobert Jaeschke/O=3DHumboldt-Universita=
et zu Berlin/ST=3DBerlin/C=3DDE/[email protected]/GN=3DR=
obert/SN=3DJaeschke/2.5.4.97=3DGOVDE+BE"
> gpgsm:                 aka "[email protected]"

This output includes the key id which I can then use to get more
information about the key.=C2=B2

How can I see the id of a key used to sign a message in mutt?

Best regards,
Robert


=C2=B9 as described here: https://github.com/neomutt/neomutt/issues/3567
=C2=B2 e.g., with gpgsm --list-keys E476ADAA614A7E1CFDC3D5D17F378D998076E616
