Had to change our router wep key to 64bit from Have a laptop that's still set to the key. WEP includes the IV in clear in the first few bytes of the frame. XOR is a mathematical algorithm which I am not even going to attempt to explain.
There is a copy of cygwin1. The peek. You will get a peek driver not found message if you dont do this. You also need to go to Wild Packets to pick up a new driver for your card. I have found that the most common cause of stress when trying to crack WEP is incompatible hardware. The Airopeek driver from Wild Packets is not compatible with all types of hardware.
There is a list of supported adaptors and the relevant driver you need to use on the web site. This card works with Whax, Auditor and BackTrack pretty much straight out of the box. It is my preferred Wireless Adaptor and has not let me down yet. Most cards that are Atheros based will have the Atheros logo on the side of the box, use one of these if possible.
Connexant cards are also a complete waste of time which I found out the hardway so please do not even think about buying one of these if you want to crack WEP.
Aircrack-ng Cygwin1. Now we need to install the driver you have downloaded. The peek driver will not let you use your Wireless Adaptor in the conventional way.
The Peek driver puts your Adaptor in to a promiscuous mode to allow it to sniff all Windows may display a prompt warning you that the driver is not digitally signed, if ths happens click continue anyway.

If you have questions about Aircrack a good place to post them is on the Netstumbler Linux Forums as I believe the author checks here quite often.
A new window opens now which will search for all installed wireless adaptors, give it a numerical signature and display the following:. The USA only uses up to channel 11 and Europe use up to channel If you want to scan all channels use the 0 option. The resulting capture file will only be useful for WEP cracking. The resultant file will be saved as an.
IVS file. This is not always broadcasted by the AP but we will need it to associate with the AP later on. The second part lists any associated clients that are talking to the AP. If it is not in the list, regardless of if you have the correct WEP key or not, you will not be allowed to associate with the AP. You will also leave an entry in the logs. This is a very helpful feature of Airodump that informs us what we need to spoof our MAC to when associating with the AP. The more we can get the more chance we have of cracking the WEP key.
This is where the very handy feature of Airodump amending to existing files is useful. You will still have the white command prompt open so just type Aircrack-ng at the prompt. Aircrack-ng 0. As this paper is getting a bit long I will just cover the options we need to crack a WEP key from a file.
If you want to try the other options out.. The helpful descriptions provided speak for themselves really. You can also use the —f switch, which is the fudge factor switch. The keys are well-encrypted by Windows operating system, so you cannot watch them with RegEdit.
Q: What is the Registry location that Windows Vista stores the wireless key? A: Windows Vista doesn't store the wireless keys in Registry anymore. The keys are stored and well-encrypted inside the.
In these cases, the wireless keys are stored in other locations, and WirelessKeyView cannot retrieve them.
