How to setup git with GPG keys for that green verified mark

Setup Github GPG keys.md

1. Generate your key

gpg --full-generate-key

2. Export the key, copy the output and add it to github's gpg keys section

gpg --armor --export <key-id>

3. Turn on commit signature and set default signing key

git config --global commit.gpgsign true
git config --global user.signingKey <key-id>

To get key id, run:

gpg --list-secret-keys --keyid-format LONG

In the output:

/home/user/.gnupg/pubring.kbx
