Generate the keys directly on the YubiKey device.There are technically two ways to do this: Generating a Primary PGP Key with Signing, Encryption, and Authentication Subkeysīefore we can start using the YubiKey for any PGP related task we need to create our primary key and related subkeys. If you think something should be changed to make it better, let me know your thoughts in the comments. I’ve followed several guides and made plenty of mistakes which I’m hoping to clear up in this tutorial.
Finally, note that I am not an expert with PGP. Also note that you should be making and maintaining a backup of everything we do in case you end up wiping out your keys. If you’re using Linux, you can probably follow along with little to no problems. While a Mac is not a requirement, if you’re using Windows, the steps will likely be different. In this tutorial, we’re going to explore using the YubiKey as a smart card for storing our PGP signing, encryption, and authentication subkeys.īefore we get too invested in this tutorial, I want to point out that I’m using a Mac. For example, the YubiKey NEO and YubiKey 5 have support for U2F, FIDO2, OpenPGP, OTP, and a bunch of other crazy technologies. In previous tutorials I demonstrated how to implement U2F in your web application, but most YubiKey devices do so much more than just U2F authentication. As you know, based on a few of the tutorials that I’ve published recently, I have a YubiKey that I’ve been learning how to take full advantage of.
