| It's a pretty silly implementation, though. The point of hashing

Remembering that if you have enough access to get to the database, you
probably have enough access to alter the Zope app itself (either by inserting
a new user, or through other permissions). So at that point it would be
trivial to alter any code to simply spew out the plaintext passwords (although
needing them at this point would probably be pointless).

I wouldn't worry about people trying to bruteforce your passwords, there are
many, much more efficient methods to grab zope passwords, once you achieve a
certain level of minimal access.

Yeah well...
