comment Length of passwords that are rainbow table safe
I'm probably being a bit pedantic, but doesn't /dev/urandom reuse the kernel's entropy pool if there isn't enough left? So, if we want to get as close as possible to 48 bits of entropy, we'd do well to use /dev/random, no?

@Iszi: Fair enough. Although, the quote appears to originate from a certain The A-Team movie - or at least it is used in it. :)

comment Would an unnecessarily long password degrade performance of a WPA2 wireless network?
@Iszi: Sure, if you make sure that the medium on which you hold the password is secured. An encrypted volume is secured. A piece of paper is not secured. A text file on a thumb drive is usually not secured. And really, if the password's going to be so long, why not just make it something memorable? At those lengths the admissible character set won't matter much anyway. Of course, this required an obligatory XKCD strip.

comment Would an unnecessarily long password degrade performance of a WPA2 wireless network?
@SteveS: I'd say, yes. When it's so long and random, that you can't hope to remember it (not in a million years), and have to resort to writing it on a piece of paper or holding it in a text file on your USB drive, then yes, I'd say it's too long. But I guess I'm just against the idea of trying to make security really big in the hopes that it will work better. Or perhaps overkill makes me uncomfortable?

@Iszi: Well, I don't have it off hand to test my theory, but it definitely looked ridiculously long. For the sake of argument, let's say that the password is indeed "just" 63 characters - I think that's still too long to be useful.
