finaly i´m done with developing
and now i want to block my card
for more developing.
Can someone tell me how i change
the GP-Key on my card with GPShell?
I found that command but don´t work
what am i missing?
Code: Select all
open_sc -security 3 -keyind 0 -keyver 0 -key "currentKey" -keyDerivation visa2 // Open secure channel
put_sc_key -keyver 0 -newkeyver 0 -mac_key "newKey"-enc_key "newKey"-kek_key "newKey" -current_kek "currentKey"
With this error:
Code: Select all
put_secure_channel_keys() returns 0x80206A80 (6A80: Wrong data / Incorrect values in command data.)
I also tried:
Code: Select all
put_sc_key -keyver 1 -newkeyver 1 -key "newKEy" -keyDerivation visa2
but got this error:
Code: Select all
put_secure_channel_keys() returns 0x80206A88 (6A88: Referenced data not found.)
