I know you want to have a verified badge like this next to your commits on github. On one hand, it's awesome. If you're not famous and aren't verified on Twitter, this feels almost as cool. The second reason is because you're reading this article!
Setting up gpg keys can be a little annoying. Even if you follow the simple steps to generate one and let git know about it, you're going to be stuck typing a password on every commit if you don't setup an agent to handle adding it to your keychain for you. I've followed a couple different guides across multiple computers to end up with a combination of them in this guide. With that being said, get started by having homebrew installed, and we'll go from there.
brew install gpg2
The following is straight from GitHub
gpg --list-secret-keys --keyid-format LONG
If you're confused about finding your key id, check step 11.
gpg --armor --export KEY_ID
Copy the output from above and add it to GitHub
git config --global commit.gpgsign true
git config --global user.signingkey KEY_ID
The following was found from this guide. After running the above commands, git will sign commits with your key. You just have to setup pinentry so that you wont have to type your password on every commit.
brew install gpg-agent pinentry-mac
Enable agent the agent:
echo "use agent" >> vi ~/.gnupg/gpg.conf
Paste these lines:
use-standard-socket pinentry-program /usr/local/bin/pinentry-mac
Link pinentry and agent together:
vi ~/.profile # or other file that is sourced every time
Paste these lines:
if test -f ~/.gnupg/.gpg-agent-info -a -n "$(pgrep gpg-agent)"; then source ~/.gnupg/.gpg-agent-info export GPG_AGENT_INFO GPG_TTY=$(tty) export GPG_TTY else eval $(gpg-agent --daemon --write-env-file ~/.gnupg/.gpg-agent-info) fi
That's it! After sourcing your bashrc or zshrc (
source ~/.zshrc) or restarting your terminal, run a git commit. You should be prompted to type in your password and check the box to store it in your keychain. All further commits will be auto signed!
Hopefully I'll have a more interesting post next week, this week has just been insane for me.
