1. Use git log --show-signature to see what commigs you have

2. Get the commit hash of the last commit you want to sign (this will make the command stop at the given hash, will include it in the new signed commit)

GIT_EDITOR=true git rebase --exec 'git commit --amend --no-edit -n -S' -i LAST_COMMIT_HASH_YOU_WANT_TO_SIGN
