About Choosing Wireless AP Keys

[k61824]

If I am using a Pseudo random number generator (PRNG) to generate strings for keys and SSIDs for my wireless AP (WPA2/AES), does it make a big difference whether I use a cryptographically secure PRNG or not? (as in are there tools that exploit the non-securedness of PRNG string generations?)

I don't think so, as the vast majority of WPA2 keys are not going to be hard random. If WPA2 was weak enough to require hard random keys, then it would be effectively broken and we'd be looking for something better.

Of course hard random is theoretically better, and if an attacker has a good idea of your own weak key generation technique, then you could be at risk.
