I don't think you are going to find a better solution than htmlawed. It is a
drop in replacement for kses. It is still being developed (as far as I know). It
works with the existing config options. And there is a patch. What more do you
need? Perhaps if that were articulated someone could find a solution.

As I understand it, SHA-1 is only broken for long term use - digitally signing a
mortgage document, for example. SHA-1 is only damaged. It is not cracked. For
short term hashing, it is still usable.

Well, I try to stay up to date. The real flaw with Geeklog's password hash is no
salt. That makes it vulnerable to dictionary attacks. Eliminating that flaw is
the first minimal step. As long as the salt is unpredictable and different for
each user you eliminate known value attacks. (Someone logs in, sets their
password to something, then attacks the hash to find the salt.)
