Welcome everyone,
I'd like to know how excaly does the EFI or MBR bootloader convey decrypted by user-entered password master key to the driver. Is it done by placing it to some predefined memory adress, which is later read and processed by driver process? Maybe it's passed as a kind of arguments given to Windows EFI bootloader during chainoading and then transfered to the driver?
