I'm trying to replace default keys for a JCOP20 card using GPShell,
but after opening secure channel, and running this line:
put_sc_key -keyver 0 -newkeyver 1 -mac_key 00112233445566778899aabbccddeeff -enc_key 00112233445566778899aabbccddeeff -kek_key 00112233445566778899aabbccddeeff
(assuming that I want to change those three keys to "00112233445566778899aabbccddeeff")
I get (6A80: Wrong data / Incorrect values in command data.)
Am I doing something wrong?
