Because everyone seems to be putting something in on this conversation...
I think that if anyone is seriously interested in cryptology, cryptography, and cryptanalysis, go pick up a copy of
Applied Cryptography, Second Edition
by Bruce Schneier, rather than obviously maliciously trying to crack the encryption of the FIRST manual. Or even, as another alternative, encrypt something yourself, and try to decipher it.
Not that it's realistic for anyone to be able to actually decipher the manual before Saturday, but just realize that just looking at a part of the manual would give you, whether you wanted it or not, a completely unfair advantage over all other teams in FIRST. Some people don't mind taking whatever advantages they can get ahold on, no matter any code of ethics, but I think most people would actually like to have a level playing field for this season.
