To restore a key you need to use gpg's edit-key command. That requires
that you pass it a key-id or a user-id. You should give the key-id
which was stored on the card. Note that the public key as well as the
secret-key stub are not stored on the card.
The backup file only contains the parts of the key which will be stored
on the card. After the --edit-key prompt is shown, enter the command
"bkuptocard" and follow the instructions. If you don't have the public
key available, you may give any other key-id to enter the key-edit menu.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
