Methods for the Improvement of 'common' Javascript password protection

Here you are, sunny boys:
The correct password, that would land you on my 'devious' page on 20 MARCH 1998,
would land you on 
vournt.htm on another march day... another,
not any
other day... duh
Of course, any
capable reverser will be able to find the way to both pages, immediatly, as well...
:-)
This kind of site protection is more and more common on the web, as you will
quickly see, the code works as a generator: if you introduce the name
of a url, you get the password to that url as well... a self-reversing protection
scheme...
