On average how fast can they blaze through one of those really huge lists to crack a very random passphrase ?

I guess if you have something you really need to keep secure use pencil and paper and keep it under lock and key.

To get through a 128-bit key, average of 10 minutes.

If you need a wireless network to be secure, use RADIUS :)

Okay, I was getting very confused because I was thinking in terms of cracking (by brute force) the entire 128 bit key space (which would be monumental and require enormous storage) and not thinking of the hash functions and the fact that they are non-injective mappings.. Combined with the enormous size (cardinality) of the pure 128 bit key space i.e. 2^128 is quite significant...(i.e. collisions). Much shorter to use a set of possible hashes based on a given character set, i.e. the typical keyboard.

I'll take a look at RADIUS. I like to try and keep it secure.
