This is something to start with. It assumes to find the words in the
"words-#.dic" files where # represents the
order of the words... so its probably not as clean as you'd want it to be.
Also i think the problem would be with loading the file into the memory, when
it will get large enough to be
representing the true key i think you'll be having some serious out of memory
issues.
