Encrypt Your Dog (Mutt and GPG)

I’m going to kill two birds with one stone and describe security as applied to a piece of software that has gotten a lot of play in my column through the years: Mutt. Those of you who are familiar with my column know about my long history as a Mutt user. For those of you who aren’t acquainted with it, Mutt is a command-line mail client (some would say Mail User Agent or MUA) that is highly configurable and uses vi key bindings that so many of us know and love.
