Hi all
I have got a filter driver which can encrypt all the drives except the boot
drive ( W2k , XP ) . I also want to encrypt the boot drive ( more like
complete hard disk encryption like DCPP ) . If i encrypt the Boot drive i
will have to make a pre boot decryption routine by overriding the INT 13 .
As of now encryption / decryption routine is a simple XOR so not much ASM
code is required in overriding INT 13 .Now i want to ask will such a thing
work ? When is the filter driver loaded .
Or is there a better strategy to go about doing such a thing of sector level
hard disk encryption .
Hoping for help from all you experts
