How does one handle GPG key(s?) with two different email addresses, one on GitHub and the other on GitLab.
I have a college email address and they force me to use GitLab.
I have a private email address which I use for GitHub.
I want those two completely separated, but there are some issues.
I already have separate SSH keys and that works fine, but when I try to utilize two GPG keys, I get GPG signing error unless I set gpgsign = false in global .gitconfig, but nothing gets signed then.
Git has configuration both for Global and Local.
Global means settings for every repository on your computer. Local means settings for a single repository.
To set global configuration for signingkey use:
git config --global user.signingkey <gpg-key-id>
To set for local, switch to repository you want to change configs for and use:
git config user.signingkey <gpg-key-id>
When you execute git config user.signingkey you should see proper configuration.
