They state 3072 because that is what GnuPG supported at that time; the
cards supported 4096, though.  Since 2.0.18 GnuPG supports 4096 with
those cards.

There is still no reason to use it 2048 is more than sufficient.  IF you
think you need more, you should ask yourself several questions.  One of
these questions should be, whether you have checked the chip design and
the firmware of the card.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
