What is it we do when we implantisomd5 which is used by media check? Can't
you make use of that?
I am not sure how you do that - how can you include inside a piece of
data a checksum that uses the data {including itself} to calculate the
checksum ? {sounds like one for the crytologists}. Perhaps it is outside
the data area, but then you have no way to know if the implanted
checksum is broken or that data itself {although I imagine it is likely
to be the data}.
What I am after is a checksum for each file present within the iso, not
the result for the whole iso. Is there such a thing already present ?
