Thanks for the reply! This is actually something I'm working on now,
only for sha-1. I was hoping to use call_external but after fighting
with that all day (xp+cygwin+student edition of idl....), I think
spawn is probably the easiest answer. Now to see what kind of
performance hit I take! =-)
I definitely understand about the prioritizing too - I'd like to do
it, but there are too many other things that also need to get done
first.

I have wanted to do this before too, but the want has never moved high
enough on the priority to write md5 as an idl routine.
One thing that I played with a bit which is not portable or elegant
but does seem to work (on my mac and should on *nix, no ides about
windoze)
