Do not force a user to specify the PIN/PUK/mgmt-key on the command line.
Instead, query the user to supply them through stdin when required for
the requested operation. This is both more user friendly and more
secure, since the secrets do not end up in the shell history and/or
visible to shoulder-surfers on the terminal.

the card functions only accepts key components of correct size
so here we add 0 before if they're shorter (usually one byte shorter)
thus fixing the issue where the card returned 6f00
