what does GP key mean

Post by andromeda92 » Wed Sep 02, 2020 1:32 pm

what does GP key mean, are these the default keys (404142434445464748494A4B4C4D4E4F)
or is it a key to encoded in the card which is not part of the three keys (S-ENC, C-MAC, DEK)?

if i want to change default key,

i need to create cryptogram ?
i need to calculate RSA key ?

is the card automatic calculation
