I saw David McNab's Python implementation. Unfortunately, as near as I
can tell (and suggested in the list archives also), McNab actually
implements a different algorithm than hashcash. It might (or might
not) be equivalent in security; but I cannot see any directly way to
transform what he computes into an actual hashcash stamp.
I created a Pure Python module today that seems to conform with the
hashcash v.1 standard. But I probably missed something. It's just
barely tested--call this an alpha version. Still, I figured I'd send
it out here.... if anyone sees something I've done wrong, please let me
know so I can correct it before distributing the module more widely.
Yours, David...
