Bear in mind an md5sum is only 128 bits. It is impossible for there to be only one file that results in that sum, given that a file can be any size, with any value in each of the bytes. However, it's virtually impossible to change a file so that it has the same md5sum and is still sensible in the intended application. A small change in the original file makes a big change in the md5sum.
Exactly. But it will also be possible to find several files of the same size that produce the same checksum. I have no idea how many, but there will be a number that I think could be calculated. - -- Cheers, Carlos E.
