I would really like to see Ed25519 and Curve25519 DH support in a card.

For the old curves the card should behave similar to gpg-agent; thus
being protocol neutral and it is not required that the rfc-6637 ECDH
algorithm is implemented by the card.

If the NIST curves are found to be bugged we should also be cautious
with the Brainpool curves.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
