Can I use master key for a encrypt job? All the time I used user keys, they work fine, but as I load encrypt with master key ID, s32 says that key is invalid. Is it possible at all, or master key is for authorisation and loading other keys only?

Hi Denis,
no, that's not possible. MASTER_ECU_KEY can be used only to update other keys or to reset the device back to factory state. This behavior is given by SHE specification.
