Well, you didn't give a Delphi version number, but if you're on D2007 or later you might want to check out this article.

Answer 2

Compare your results with:

• md5(file_get_contents( )) in PHP

• hash("md5", ) from the PHP hash framework extension

• the command line programs md5(1) aka md5sum(1)

If all but one agree what the sum is, then you know where to dig.
