How to sign git commits

1. Generate SSH Key (though existing one can be used also)

ssh-keygen -t ed25519 -C "1190812+alexgalkin@users.noreply.github.com" -f ~/.ssh/github_signing_key

2. View and copy the full public key and add it to your Github profile as a Signing key

cat ~/.ssh/github_signing_key.pub

3. Configure your new key for signing using git

git config --global gpg.format ssh
git config --global user.signingkey ~/.ssh/github_signing_key.pub

4. And when you do commits use -S parameter

git commit -S -m "fix: resolved the issue with keys signing"
