Create strong key
We want an elliptical curve key. It's baked in! But hidden.

PIN entry in emacs
It is neckbeard-borked out of the gate. Fix is here.
PIN entry over ssh
You can in theory decrypt a file over ssh to STDOUT without writing it to disk, but PIN entry fails by default:
ssh secretbox gpg -d secretfile.gpg
Two fixes are required to get PIN entry to work:
- Use curses for PIN entry on the secretbox:
[secretbox] emacs ~/.gnupg/gpg-agent.conf allow-emacs-pinentry allow-loopback-pinentry pinentry-program /usr/bin/pinentry-curses
- Tell ssh to use tty:
ssh -tt secretbox gpg -d secretfile.gpg
