Re: Cracking WEP and WPA keys

Would the following attack be feasible for obtaining a WEP key?

Set up an AP with VERY strong signal and same SSID as the one used by
the target network. After that, the client should be able to attempt
to connect to your AP (you send stronger signal than the legitimate
one) and send you the WEP which you could sniff from the AP itself.

After that you're done and the key is yours.

Am I talking non-sense here? Wouldn't the WEP key be sent to the AP in
the *clear* at the beginning of the handshake? Otherwise how can the
AP check whether or not the client is using the right key?

I've never tested this and my assumptions might be based on incomplete
and inaccurate knowledge about how wi-fi technologies.
