An older version of adobe had a flaw, there were a maximum of 1024 keys to be tried to crack any pdf. Not so now.

Although, if security is an issue, theres always RC5, which, for this purpose is essentially uncrackable (Theres a distributed computing project goin on now, using a 72bit key, that cracks 138,905,230,942 Keys/sec, and its 0.287% to the solution after cracking for ~4 years)

It would really be nice to have them early though, I won't have internet where I'll be watching the kickoff.
