Hacking Game

I never interest of hacking game before because alot of them use an English as a language.
Finally I found an Indonesian hacking game

I have a plan to make a review or say it a clue to resolve the game after I finish all the level.

That's why I left this blog for a moment to play the game.

I joined at July 2nd 2008, and after July 4th, only one level left to play.
It's a Cryptography level 4.
It's hard to finish because the master of the game did not exactly create the level as a RC4 cryptography (I found about it in forum).

I still confuse how to create php program to resolve that level (I only know php language program )

Suggestions and help are welcome
