Thank you, I understand the process better now.
So now, my problem is related to the external authentication process. In
order to authenticate to the card (so that I can select the applet that I
wish to run), I need to encrypt a nonce with a DES key. I am thinking of
using the OpenSSL DES library for this. However, in Eclipse the key list is
printed with 32-bit keys, something like:
set-key ${CURRKEYS}
print-key
1/1/DES-ECB/0123456789ABCDEF0123456789ABCDEF
1/2/DES-ECB/0123456789ABCDEF0123456789ABCDEF
1/3/DES-ECB/0123456789ABCDEF0123456789ABCDEF
However, the normal DES ECB standard uses either an 8-bit key (single DES)
or a triple 8-bit (24-bit) key in the case of 3DES. So how can I perform
the DES encryption with 32-bit keys?
Regards,
Mladen
