I finally got around to getting a Yubikey NEO last week and along with setting it up for 2FA for some of my online accounts, I took the opportunity to generate a new PGP key.
I mostly followed Simon Josefsson’s excellent post on the subject and ended up with a new private key and set of subkeys.
The one snag I had was getting it to work with GPGTools for Mac OSX – I kept getting the message “card error” when trying to access it. I upgraded to the latest version (with GPG 2.0.30) today and it seemed to work, though I also noticed you can’t use the Yubico Authenticator at the same time as using the GPG tool so that may have explained my problems.
My new key ID is 804EFECC, a copy of which can be found here and on Keybase.io.
