GnuPG for GitHub on macOS with fish

Generate GPG key

Choose 4096 bits with otherwise default settings.

gpg --full-generate-key

Find your GPG key

gpg --list-secret-keys --keyid-format=long

should produce:

/Users/hubot/.gnupg/secring.gpg
------------------------------------
sec   4096R/your-gpg-key-here 2016-03-10 [expires: 2017-03-10]
uid                          Hubot 
ssb   4096R/42B317FD4BA89E7A 2016-03-10

where your GPG key ID in the above example is your-gpg-key-here (but will actually be a series of numbers and letters)

GPG public key block

gpg --armor --export your-gpg-key-here

Copy and paste the public block, including -----BEGIN PGP PUBLIC KEY BLOCK----- and -----END PGP PUBLIC KEY BLOCK-----. It should look something like this

Add GPG to GitHub

1. https://github.com/settings/keys
2. Click New GPG key
3. Paste in your public block, then hit Add GPG key
4. Optional: turn on Vigilant mode

Add to Git and fish

git config --global user.signingkey your-gpg-key-here
set -Ux GPG_TTY (tty)

Optional: automatically sign each commit

git config --global commit.gpgsign true

Otherwise, use the -S flag (e.g git commit -S -m "your commit message here")
