Install GPG and Keybase

brew install keybase
brew install gpg

Generate Key Pair in GPG

gpg --gen-key

Add Secondary Email to your GPG Key

This is useful if you have a work email you also commit as.

gpg --edit-key blainesch@gmail.com

In the GPG shell:

adduid

Export Public Key

Give your public key to Github.

gpg --armor --export blainesch@gmail.com

Add GPG key to Keybase

This will copy your public key to Keybase.

keybase pgp select

Export Private Key

I imported this into 1password. Skip this if you this is managed by keybase.

gpg --export-secret-key -a blainesch@gmail.com > gpg-private.key

Import Private Key into GPG

This is useful if you have multiple computers.

gpg --allow-secret-key-import --import gpg-private.key

Signing GIT Commits

To obtain your key (for me this was 8D515E0C), run the following and look for "sec:" which stands for "secret key".

You'll see it in the following format: length/KEY creation_date.

gpg --list-secret-keys

Then, add these lines to your ~/.gitconfig

[user]
  signingkey = 8D515E0C
[commit]
  gpgsign = true

Or use the command line

git config --global user.signingkey 8D515E0C
git config --global commit.gpgsign true
