Which one? It's pretty expensive to do this kind of checking.
npasswd takes long enough as it is for my taste.

So far as I know, they're the same, or at least very similar.

What are you talking about? Find me a commonly-used operating system
that can't recognize 256 characters of ASCII and print most of
them. I dare you. I don't care if the upper 128 aren't the same
printed character between systems; as long as I know the ASCII
codes I used in my password and how to generate them on various
systems, I can use them. And do, on Unix (including Solaris, NetBSD
on three distinct keyboard setups, Linux, and NeXTStep), Mac OS (9
or earlier and X), and Windows (whatever).
I have more to say about the Perl you attached, but I don't have
time right now to actually think it all through and type it up
coherently. (There are arriving freshmen to tend to.)
