Hey guys I dont know if this is relevant but it might help lead to the .RAR file password!!
I was looking Into the alt.conspiracy group and "The Conspiracy is the cats Meow"
So I took the first letter of "The Conspiracy cats Meow" and got TCCM (which stands for The Combined Cipher Machine)
Heres some info on the Cipher Machine
Maybe someone who's a little better at the whole decoding thing can take a look and see where it gets you
EDIT!!!! NEVERMIND :D
