4-Way Handshake confusion

[qweasd]

@pragmatic: Well done with the description

So, the rainbow tables you are referring to are precomputed PMKs which reduce the time significantly since the most computationally intensive task in WPA2 cracking is PMK computation.

After reading the explanation provided by pragmatic, this is the conclusion I came to. I verified this by using precomputed PMKs and noticing how slow the cracking process was(not a simple hash lookup).

Thank you guys for all the comments. Really helped out.
