Arrow Encrypted Game Manual - Could we crack it?

FIRST FRC Password Convention:

Past three years:
2014: 3Zones2Goals1Alliance!
2013: sAucersFlyRobotsClimb!
2012: !HotShots!KnowBalance!
2011: 5Time4For3Robots2To1Dance!

Uses AESv2 128 bit for PDF encryption

At first glance, it seems pretty secure. However there seem to be a lot of patterns as to how the passwords are chosen.

Patterns:
1) always 22 characters after 2011
2) all of the words used are english and would appear in the dictionary
3) they use mixed case
4) a word is never separated by anything special, and no character substitution is used
5) only around 3 or 4 words are used
6) they always end with a "!" character
7) in all years but 2013 the first character has not been a letter

Idea:
Create a program that generates a wordlist based on the rules FIRST seems to follow when creating the passwords, split the wordlist up into smaller segments, and let different teams try different segments until the correct key is recovered


Thoughts?

Re: Encrypted Game Manual - Could we crack it?

A more important question might be: Should we crack it?

Re: Encrypted Game Manual - Could we crack it?

The manual is encrypted using 128-bit AES encryption. From the decryption test page.

[128-bit AES encryption] is a current standard considered by the US Government as completely secure for short (weeks) periods of time

Yes, AES is pretty strong, but in this case it is only 128 bit, and the key is fairly predictable. I'm not suggesting brute force. A gpu could probably churn out tons of guesses per second and testing wordlists we create using the patterns in their password shouldn't take more than a couple hours at most.

I posted the key on CD, but they deleted it. Oh well

"Tons of guesses per second" is unbelievably ridiculously optimistic. The best you can get using modern GPU's is a few guesses per second. There are 3.4E38 possible keys. Do the math.

Re: Encrypted Game Manual - Could we crack it?

It really concerns me that even with this small sample, there are that many people who want to crack the manual. Come on...what happened to GP? It's just a game, guys. Even if you crack it (you can't), you'll only feel bad throughout the season when either A) you don't win, or B) you do win, but feel dirty about it because you had an advantage. In any case, you're not having fun, and that's a huge part of why we do this.

Re: Encrypted Game Manual - Could we crack it?

Guess I should've read more carefully, I thought this was for cracking it after the password was released.

After the password is released, I'm all for cracking it...

...Cracking it open and reading the whole thing.


But before the password is released, I got one thing to say: Locks ain't for pickin'. They're there to tell you not to open whatever is locked.

Re: Encrypted Game Manual - Could we crack it?

I don't like this thread. It's silly, as you won't be able to crack the manual password, but makes us look like a bunch of goons because we're trying to crack it.

Kickoff is Saturday. We should take these last few days to relax, see our family, and get ahead with our work. I am sure that there will be plenty of technical challenges to deal with this year.

EDIT: 666th post!

Re: Encrypted Game Manual - Could we crack it?

It's a little sad to see that some people would try to crack the game manual before the release. I've always wanted to try after kickoff just to see how long it would take. That is more an experiment of the encryption.

Re: Encrypted Game Manual - Could we crack it?

Especially in the light of the other thread - I'm all about non-serious discussion around cracking the manual, but let's keep it above the belt.
