FWIW, I've used "gpg --with-fingerprint public-key-file.asc" for what
seems like years to do this sort of quick fingerprint check of keys.
It's particularly handy with linux distribution package signing keys,
which are typically not something I have any need to import to my
On a fedora-25 system:
$ gpg --version
gpg (GnuPG) 1.4.22
$ gpg --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-25-primary
pub 4096R/FDB19C98 2016-03-31 Fedora 25 Primary (25) <fedora-25-primary at fedoraproject.org>
Key fingerprint = C437 DCCD 558A 66A3 7D6F 4372 4089 D8F2 FDB1 9C98
$ gpg2 --version
gpg (GnuPG) 2.1.13
$ gpg2 --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-25-primary
pub rsa4096 2016-03-31 [SCE]
C437 DCCD 558A 66A3 7D6F 4372 4089 D8F2 FDB1 9C98
uid Fedora 25 Primary (25) <fedora-25-primary at fedoraproject.org>
I haven't looked at the documentation for --with-fingerprint in a
while, but it does seem like it's at least leaving out some details
regarding its use on key files which are not imported.
I have no idea whether those differences are intended and should
simply be documented or it's considered a bug that --fingerprint and
--with-fingerprint differ in handling unimported keys.
Also, both 2.1.13 on fedora 25 and 2.1.22 on fedora rawhide, the
command above complains about the show-only option:
$ gpg2 --version
gpg (GnuPG) 2.1.22
$ gpg2 --with-fingerprint --import-options show-only --import < /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-25-primary
gpg: unknown option 'show-only'
gpg: invalid import options
Is there a typo in that command or is show-only not in the latest
release of the 2.1 branch?
The most overlooked advantage to owning a computer is that if they
foul up, there's no law against whacking them around a little.
