i spent 2 hours today, trying to use the command "external authenticate".
I have created derived keys on the card (Multiapplication), but how do I derive the key in the terminal program??
I cant find a function like "derivekey(masterkey, serialnumber/seed,Algorithm)" or so..
I am right assuming that i cant use the lcbuildkey command in any way in the terminalprogramm?
I also found no examplecode that demonstrates how to generate the correct response for use in the externalauthenticate command.
the getChallenge command works, but thats only the first part of the quest... ;)

thank you for some pointers in the right direction,
Jonathan from munich
