That's a big rainbow table. Like, with just precomputed values and random ascii character passwords it's on the order of 10^42^ entries. You can shave that down a bit probably with all the tricks rainbow tables use, but I think you're safe.

    10^31^ is ridiculously huge too. The NSA probably works on EB scales, which is "only" 10^18^ bytes. If you can get up to 10^22^ equally likely passwords you're fine against dragnet, brute force-style attacks. (If you're zombie Bin Laden and the NSA will stop for a whole year cracking your drive, and doesn't have any shortcuts, maybe you need 10^39^ I guess)

    That being said, if more characters is no problem, go ahead and do that. I'm not saying more security for free is a bad thing.
