Install the required libraries to access your YubiKey with GPG, if you didn’t already (Linux): # apt install gnupg2 scdaemon libpcsclite1Ĭheck that your YubiKey is connected and recognised, and print out the keygrips and creation timestamps of your keys: # gpg2 -card-status -with-keygrip Application type. newer than the 2.2.4 version that ships with Ubuntu Bionic). I recommend a GPG version 2.2.6 or newer (i.e. I was able to recover my public keys from my YubiKey 4 even on a brand new, erased computer. However, I investigated this and found that this common wisdom wasn’t true. If you don’t have such a backup, you’re screwed. The common wisdom on the Internet is that this is because YubiKeys (and Smart Cards in general) don’t store your public keys at all, they only store your private keys, so you must import your public keys from a backup or a public keyserver instead.

Have you ever generated GPG keys, loaded them into your YubiKey, and then thrown away/erased your computer? You’ll discover that when you take your YubiKey to a new computer, GPG refuses to automatically import your key when running -card-status.
