Class WinImageFingerprint

source code

Fingerprint the current image.

This parameter tries to get something unique about the image quickly. The
idea is that two different images (even of the same system at different
points in time) will have very different fingerprints. The fingerprint is
used as a key to cache persistent information about the system.

Live systems can not have a stable fingerprint and so return a NoneObject()
here.

We return a list of tuples:
   (physical_offset, expected_data)

The list uniquely identifies the image. If one were to read all physical
offsets and find the expected_data at these locations, then we have a very
high level of confidence that the image is unique and matches the
fingerprint.
