- Index
In all the exercises we have done till now, we cracked the WEP and WPA keys using various techniques. What do we do with this information? The first step is to decrypt data packets we have captured using these keys.
In the next exercise, we will decrypt the WEP and WPA packets in the same trace file that we captured over the air, using the keys we cracked.
