Weird copyright statement for a new file, did you base it off another
one, or just copy-pasted the boilerplate?

The error message sounds a bit strange to me, I would expect the
filename after "in file [...]", but you print the expected checksum.
Also, 'invalid' sounds a bit like we found something which is malformed
checksum (no hex), so maybe "checksum mismatch in file, expected %X,
found %X" or something?
