"...quite astonished at the apparent requirement to checksum a 'window'...calculate a checksum on the whole file..." (Marshall)

#MeToo. Probably this is yet another sick assignment by some sick professor?

For a more serious/practical use of checksums you might be happier using digest from Path::Tiny:

my $object = path($file)->digest($algorithm);. The default algorithm is SHA-256.
