What you're looking for is actually a pretty complex thing. You *could*
in theory manage /etc/passwd (and its "shadow" file) - you can find
crypto primitives like MD5 and DES on the 'net, but note that you must
run your script under the 'root' account in order to write (and even
read!) the passwd database. The same goes for using os.system and the
built-in OS utility. Be aware of security implications if you're running
your web server under the root account.
