GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

git config --global gpg.program /usr/local/MacGPG2/bin/gpg2
git config --global user.signingkey A6B167E1 
git config --global commit.gpgsign true 

1. Add this line to ~/.gnupg/gpg-agent.conf

pinentry-program /usr/local/MacGPG2/libexec/pinentry-mac.app/Contents/MacOS/pinentry-mac

1. Add this line to ~/.gnupg/gpg.conf

no-tty

Keybase.io

Import key to GPG on another host

% keybase pgp export
% keybase pgp export -q CB86A866E870EE00 | gpg --import
% keybase pgp export -q CB86A866E870EE00 --secret | gpg --allow-secret-key-import --import

Add public GPG key to GitHub

% open https://github.com/settings/keys
% keybase pgp export -q CB86A866E440EE00 | pbcopy
