If a signature is made with a valid key and that key later expires, the signature should still be considered good. GnuPG emits in this case something like: [GNUPG:] NEWSIG gpg: Signature made Wed 26 Nov 2014 05:56:50 AM CET gpg: using RSA key FE3958F9067BC667 [GNUPG:] KEYEXPIRED 1478449622 [GNUPG:] KEY_CONSIDERED D783920D6D4F0C06AA4C25F3FE3958F9067BC667 0 [GNUPG:] KEYEXPIRED 1478449622 [GNUPG:] SIG_ID 8tAN3Fx6XB2NAoH5U8neoguQ9MI 2014-11-26 1416977810 [GNUPG:] EXPKEYSIG FE3958F9067BC667 Jason Cooper <jason@lakedaemon.net> gpg: Good signature from "Jason Cooper <jason@lakedaemon.net>" [expired] [GNUPG:] VALIDSIG D783920D6D4F0C06AA4C25F3FE3958F9067BC667 2014-11-26 1416977810 0 4 0 1 2 00 D783920D6D4F0C06AA4C25F3FE3958F9067BC667 gpg: Note: This key has expired! D783920D6D4F0C06AA4C25F3FE3958F9067BC667 (signature and signed data in this example is taken from Linux commit 756f80cee766574ae282baa97fdcf9cc). So GnuPG is relaxed and the fact that the key is expired is only worth a "Note" which is weaker than e.g. gpg: WARNING: The key's User ID is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner. which git still considers ok. So stop coloring the signature by an expired key red and handle it like any other good signature.

Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.adoc to get started, then see
Documentation/giteveryday.adoc for a useful minimum set of commands, and
Documentation/git-<commandname>.adoc for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.adoc
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email to git+subscribe@vger.kernel.org (see https://subspace.kernel.org/subscribing.html for details). The mailing list archives are available at https://lore.kernel.org/git/, https://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
