/* Note about debug:
|
||||
* To debug Device you can def the following :
|
||||
* #define DEBUG_HWDEVICE
|
||||
* Activate debug mechanism:
|
||||
* - Add more trace
|
||||
* - All computation done by device are checked by default device.
|
||||
* Required IODUMMYCRYPT_HWDEVICE or IONOCRYPT_HWDEVICE for fully working
|
||||
* #define IODUMMYCRYPT_HWDEVICE 1
|
||||
* - It assumes sensitive data encryption is is off on device side. a XOR with 0x55. This allow Ledger Class to make check on clear value
|
||||
* #define IONOCRYPT_HWDEVICE 1
|
||||
* - It assumes sensitive data encryption is off on device side.
