Field Documentation

slot_key

const uint8_t* atca_check_mac_in_out::slot_key

[in] 32 byte key value in the slot specified by slot_id. Can be NULL if mode[1] is 1.

target_key

const uint8_t* atca_check_mac_in_out::target_key

[in] If this is not NULL, it assumes CheckMac copy is enabled for the specified key_id (ReadKey=0). If key_id is even, this should be the 32-byte key value for the slot key_id+1, otherwise this should be set to slot_key.
