I'm way way behind on email, but the toybox implementation of md5/sha1
is essentially public domain (BSD license without any "copy this
license into your derivatives" clause). I've been pushing code into
busybox for years, but I wrote this is the first place for toybox, and
they replaced their old version with mine because mine's simpler, and
implements both sha1 and md5sum in the same file:

FYI.
