- Generated keys on an air-gapped PC.
- Backed-up my .gpg folder on a USB.
- Imported keys to smartcard 1.
- Keys deleted
- Replaced .pgp folder with .pgp from USB
- Imported keys to smartcard 2.
Is this setup valid and can I use same sub-keys with two completely different smartcards?
Is there a way to test those keys to make sure everything works correctly?
