The Questions is, do we attempt to build a Mr.Fusion, or do we go for the Plutonium from the Libyans?

Neither. We go for the lightning bolt.

Let's not.

Seriously, talk about cracking a password should not be welcome in this community.

It is not allowed. It will get you banned.

I highly doubt it will happen as it is a mixture of words, caps, punctuation, etc. based on the ones they have given out in the past few years. My regard for that team/member would go down the tubes extremely fast and it is never worth it, especially this early in the season.

Discussing doing it for malicious uses (such as gaining access to the game manual early) is not welcome. Discussions about the mathematics behind encryption is actually quite fascinating and I think should be encouraged. I would even go so far as to say that discussion of techniques for defeating encryption and why it is often not worth trying are incredibly useful.

Of course, if the mods disagree with this view please delete this post and let me know.

The practicality of cracking the password is negligible. The passwords have historically been strong enough that unless someone uses a botnet there simply isn't enough time to crack it successfully before Saturday. 0-day hacks into Adobe as attempts to crack encrypted files have simply resulted in 0-day exploits for internet browsers instead of actually unencrypting the files, so I also doubt there are circumvention measures available.

In short: 128-bit SSL is still going strong, so don't get your hopes up of actually reading the contents before Saturday.

Could you explain why? (Not saying you are wrong, just because I think it would make an interesting read)

128-bit encryption means 128 bits.

The number of permutations is 2^128, or 340282366920938000000000000000000000000 possible permutations.

Even with really fast processors, it would take months to brute force that. Assuming you don't really have access to some kind of supercomputer or massive distributed computing network.

Although a few recent papers have called into question the security. AES-128 encryption. If you like technical stuff, here:
http://eprint.iacr.org/2009/374.pdf

Although they conclude the encryption is fairly secure at this time, some flaws have started to appear.

It's something I've worried about since "DriveFastTurnLeft"... If the passwords were random strings of alphanumerics, then they'd be for all intents and purposes impossible to crack in the time frame -- but game hints combined with cribbed passwords, that's just bad cryptology right there!

Here is a question regarding NOT cracking the code..

I am new to the Mac universe, I am trying to download and save the files to my computer and open them with adobe which i have just downloaded. Instead of being successful, it says that the files are damaged and I don't even get the prompt for the password. Anyone with a Mac have a tip or two?

Help would be appreciated.

Just use the default Preview.app instead of the Adobe one. I never had a problem in the past. You could also try redownloading as they may actually have been downloaded corrupt (it happens).

Got it! Thanks! Computer was being temperamental.

this happened to me (albeit on Windows), after downloading and renaming the file. I tried again, this time not renaming the PDF (keeping it as Complete_FRC_Game_Manual_05Jan2011.pdf) and it worked fine.

Uhh...the passwords aren't usually just alpha. "Drive!Straight?turn.LEFT!?" is a good example. Punctuation adds a little more complexity

"Breakaway4FRC" was "simpler", but would still take a while to bruteforce.
I'm wondering if anyone's just run a bruteforcer during build season to see how long it would actually take...
