# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env | |
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced | |
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start | |
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running. | |
# Add the following to your shell init to set up gpg-agent automatically for every shell | |
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then | |

brew install gnupg, pinentry-mac
(this includes gpg-agent and pinentry)
Generate a key: $ gpg --gen-key
Take the defaults. Whatevs
Tell gpg-agent to use pinentry-mac:
$ vim ~/.gnupg/gpg-agent.conf
