I don't have a copy of 7816-12 here so I don't know any details.
However it seems that there is a version B which sends complete APDUs.
Any chance to implement that versions to get rid of the T=0 protocol
with all its problems?

There is I-D to extend OpenPGP with ECC and we are already working on an
GnuPG implementation.



Die Gedanken sind frei.  Auschnahme regelt ein Bundeschgesetz.
