If you look at the source code for the page you will see that the (lower-case) letters of the password are converted into ASCII codes and multiplied together to generate the access to the next page.
On the leaf page this product has to equal
8.112765541022159e+23
A 12 letter password including one space will give a product of this magnitude. I have been trying to factorize that number to derive the password.
In any case, once the password matches, it will redirect you to the page having the URL:
http://www.frozenagain.com/password/witty.html
That is a Null file and generates a blank page.
