That might be true with the v1 card which used a pretty old chip.  The
v2 card uses a modern chip and card OS and thus the effort to read off
the key wouldn't be worth what you will gain from it.  As it is not
possible to secretly read out the key you will almost always have the
opportunity to revoke the key before a damage is possible.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
