I recently picked up a Yubikey Neo and decided to try setting up the PGP Encryption Certificates. I was following these instructions:
https://www.yubico.com/2012/12/yubikey-neo-openpgp/ Everything was going great until it tried actually generating the keys.
Operating System: Windows 8.1
Yubikey Neo Firmware: 3.3
GnuPG Version: 2.1.1
I hit "o" on the keyboard and it sat there generting keys, yubikey was blinking. Then it dropped the following message on the screen:
Key generation failed: Not supported
At this point I ran "gpg --card-status" to see what it accomplished (if anything). It now shows a signature key, and an authentication key, but no encryption key. Perhaps this is where it failed?
Any ideas what is going on here?
