After completing my GPG videos, many of you have been emailing me encrypted messages over the years. Remember what I discussed about key rotation? Well, my subkeys expired this week, so here's how to update them if you already have them in your keyring. $ gpg --refresh-keys If it fails, specify a different key server: $ gpg --refresh-keys --keyserver keyserver.ubuntu[dot]com If that doesn't work, download the public key manually from the key server providing the fingerprint of my master certifying key, and "--import" it If you cannot verify the following signature, it cannot be said that I'm responsible for this. LOL. Let's see who's first.
