Re: breaking 256 bit AES encryption ok, just so i'm clear- there are two separate keys involved in WPA/WPA2- the PSK key (which would be the password/passphrase used to authenticate a user to the network) and an AES key used for the encryption of the data- and these AES keys change each time a client authenticates to the network. is this correct?
as far as a brute force attack is concerned- my understanding is that the more complex the passphrase the harder it will be to crack it, and i use a passphrase made of 63 random ASCII characters- so my guess is that this would be next to impossible for anyone to crack. would this be reasonable to assume?
thanks for all the replies. |

Yes to both questions. |

| Brute forcing AES is simply out of the question and will likely always be out of the question, at least until quantum computing comes around (and even then it seems unlikely).
Someone above said it would take millions of years to brute force 128 bit AES. That is incorrect. It would take trillions of times longer than the age of the universe. And even then, the energy requirements would be so large that the energy of the sun would need to be harnessed. |
