Now that we have captured the traffic to a .cap file, we will now try to retrieve the key from the captured packets. To do this we do the following:
Open another new console session and enter:
aircrack-ng -b 00:14:6C:7E:40:80 output*.cap
-b 00:14:6C:7E:40:80 selects the one access point we are interested in.
.cap selects all files starting with output and ending in .cap.
- You can run this while generating packets. In a short time, the WEP key will be calculated and presented. You will need approximately 250,000 IVs for 64-bit and 1,500,000 IVs for 128-bit keys. Note that these values are rough guidelines and other variables can impact how much traffic and how many IVs you actually need to collect.
- If the ...
