gpg

Adding a GPG key to your GitHub account - GitHub Docs
https://docs.github.com/en/authentication/managing-commit-signature-verification/adding-a-gpg-key-to-your-github-account

Generate key:

gpg --full-generate-key

List keys to get keyID

gpg --list-keys

Export public key by keyID, and save to Github

gpg --armor --export 3AA5C34371xxx

You will probably get an error about being unable to sign if you are in a remote console, to fix this:

export GPG_TTY=$(tty)

Cache password in gpg-agent:

echo "" | gpg --clearsign

~/.bashrc
alias gpgpass="echo  | gpg --clearsign"

If you really hate security, you can remove the passphrase:

gpg --edit-key XXX
  passwd
   enter password to unlock
   then enter empty password twice
   then save
