allowed_signers file for SSH/git
Git 2.34 brings support for signing commits with SSH key and having a SSH-compatible smartcard, I have to try this. It likely getting more common in the future doesn't hurt either and I have pgp-alt-wot which does about the same for PGP.
Where to find keys
- GitHub, Giteas and GitLabs expose user public keys (without useful names)
when you append a
.keys
after their profile page - Good ideas are made to be copied, so maybe there will be more repositories like this 😉
Quick howto
I don't mean this to be used directly, only to be took inspiration from. See the first link in further reading.
mkdir -p ~/src/gitea.blesmrt.net/Mikaela
cd ~/src/gitea.blesmrt.net/Mikaela
git clone https://gitea.blesmrt.net/Mikaela/ssh-allowed_signers.git
git config --global gpg.ssh.allowedSignersFile ~/src/gitea.blesmrt.net/Mikaela/ssh-allowed_signers/allowed_signers
Git commands, such as git verify-commit --raw HEAD
or git log --show-signature
,
should now recognised commits signed with keys I have allowed.
In the last command it's fine to remove --global
to only affect the single
repository you are on (while I haven't tested this), should that repository
be something only I am signing in or something I need to verify otherwise
enough to list it here.
On the last command, git config
turns it into absolute path, while manually
edited .gitconfig
can literally have the above. I wonder if the command
would understand --
before the file, but not enough to actually try it 😃
