Git error - gpg failed to sign data

Question

I just started using git and I install git and gpg via homebrew. For some reason, I get this error when i do git commit I looked at so many other stackoverflow

Answer 1

Git needs to know which key it is signing with.

After you have setup GPG, gpg-agent, and your gpg.conf files (see this guide), you need to run

git config --global user.signingkey EB11C755

Obviously, replace the public key at the end with your own. If you want every commit to be signed by default, use

git config --global commit.gpgsign true
