Re: [Opensc-devel] Request for object 5C017E in PIV

[William R. <bil...@gm...>]

Thanks for the response, ahh Ive never seen a raw request for the
discovery object... normally I see requests come in like in table 6 sp
800_73-3_PART_1 where its show as the BER-TLV object in the APDU field
is:
'5FC102' for the CHUID. However only 0x7E for the discovery object...


RSA 2048 is preferred and supported by the card, but I can try tripple
des. This might explain why the code just error's out after the
unknown request as it cannot generate the next command apdu set to
send out as it cannot handle
RSA algorithm.
