# 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](https://gitea.blesmrt.net/Mikaela/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
* For example: https://github.com/Mikaela.keys https://gitea.blesmrt.net/Mikaela.keys https://gitlab.com/Mikaela.keys
* Good ideas are made to be copied, so maybe there will be more repositories like this :wink:
## 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 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 :smiley:
