Will Purebook Work With Other GPG Cards?

I’m just curious if Pureboot’s GPG functions will work with a GPG card that isn’t the Librem Key…

PureBoot relieas on HOTP and this is a function that needs firmware implementation in the “card reader” firmware, so this is a bit specific to the Librem Key. So all card reader that implement HOTP would probably also work, though this of course also may need additional tuning on the PureBoot side to enable additional USB IDs etc.
