I have a YubiKey NEO on which I have the OpenPGP applet and I have a PGP key installed. I work on 3 different computers and I initialized the card on computer
bob. I'm now at computer
rob. Someone sent me an encrypted file, so I put in my YubiKey NEO and ran
I got the following output:
gpg: encrypted with RSA key, ID DEADBEEF gpg: decryption failed: secret key not available
Okay, so maybe I need to install my PGP public key here. I did that, and then got:
gpg: decryption failed: secret key not available
I then SSH'd into
rob and ran
gpg --list-secret-keys and lo-and-behold:
sec> 2048R/DEADDEAD 2015-02-31 Card serial no. = 0000 12345678 uid Naftuli Tzvi Kay <firstname.lastname@example.org> ssb> 2048R/BEEFBEEF 2015-02-31 ssb> 2048R/DEADBEEF 2015-02-31
What in the heck? I copied this "key" over from
rob and now things work, and yet I still need to enter my PIN for my PGP key.
When I created the key, I never imported it to disk so it should only exist on the card. Why does a secret key exist on disk(!) if the secret key isn't supposed to be anywhere but the smart card?
