I have a file mytextfile.txt with the checksum: "81b89b1908e3b3b7fcd7526810c32f14". When I move this file from my PC to my MacBook and check it, I get "e97f28bfff174f9643c088814377ada6". Does someone know why?

using (var md5 = MD5.Create())
{
using (var stream = File.OpenRead(filename))
{
var hash = md5.ComputeHash(stream);
return BitConverter.ToString(hash).Replace("-", "").ToLowerInvariant();
}
}
}
Also sorry if I'm not using the word hashing and checksum correct, still don't quite understand when to use hash and when to use checksum. Could I say my hash is: "123123"?
