My buddy Scott and myself have been trying to get his GPG system set up. Signing to him works, he can sign mails to me, I can encrypt mail to him. He can't send encrypted mails to me.
Long story short, my encryption subkey expired a few months ago. In my
defence, "expires" and "expired" look bloody similar in a monospaced
font on a terminal. I've extended the expiry date.
Grab my updated key here or do
gpg --recv-keys BAF45865 to update.
