My PGP Public Key can be used to send me encrypted messages or verify my signatures - either from emails, files or commits. My PGP Public Key has been generated from my YubiKey, and the subkeys within this "master" key are used for either encryption, signing or authentication. Please make sure that you use the correct subkey.
You can automatically download my PGP Public Key by running this command:
gpg --locate-keys hi@ted.ac
