If you only need to access md5 sums from inside Mathematica, you'll be better off
with a simple 'interface' to a shell program like md5sum. This
mmaMD5[filename_String] :=
Module[ {cmd},
cmd = StringJoin["md5sum ", filename, " > md5tmp"];
Run[cmd]; ReadList["md5tmp", String]
]
will return a string with the md5 code and some extra information you could
easily strip off.
If you don't have md5sum on your system, a quick Google search will help you
in finding one.

It is highly probable that a Mathmatica program for md5 sums won't be as efficient
as a compiled executable (oh, BTW, there also is a md5deep program out there
-Google will help you- that promises to be more efficient than ordinary
md5sum that comes with Un*ces. Dunno if that's true.)
