Set up Keybase.io, GPG & Git to sign commits on GitHub

This is a step-by-step guide on how to create a GPG key on keybase.io, adding it to a local GPG setup and use it with Git and GitHub.

Although this guide was written for macOS, most commands should work in other operating systems as well.

There's a video published by Timothy Miller explaining some parts of this guide. Discussion on Hacker News.

Note: If you don't want to use Keybase.io, follow [this guide][1] instead. For manually transferring keys to different hosts, check out this [answer on Stack Overflow][2].

Keybase proof

I hereby claim:

• I am gonzalesraul on github.
• I am gonzalesraul (https://keybase.io/gonzalesraul) on keybase.
• I have a public key ASB65wSLgzABQdYI5J5_15merYHqmG1WThWoh0ektjMYIAo

To claim this, I am signing this object:

gonzalesraul

function minikube() {
    if [[ $1 == "profile" ]]; then
        case $2 in
            list )
                current=`grep -oP '(?<="profile": ")[^"]*' $HOME/.minikube/config/config.json`
                profiles=`ls -1 $HOME/.minikube/profiles`
                echo -n "* $current"
                if [[ '' == `echo $profiles|grep $current` ]]; then
                    echo -n " (not created)"
                fi
