Re: how long does wep crack take

Hi Matthias,

DWL900 is a DLink? I called DLink to find out if they do weak iv 
filtering and they told me that they do not. I do not know if that was a 
good answer or not. If they are doing weak iv filtering you could 
capture packets for a long time and not get enough unique ones. YOu end 
up getting alot of duplicate iv's which do not help in cracking. I 
experienced this with cisco AP and pc card.  I captured over 200mb of 
packets and could not crack any keys.

What is your test setup?  I used a laptop copying a 65mb ISO to a server 
on the wired network. I used a batch file to copy/delete/copy again the 
file. I did this until I had enough weak iv's. It took about 24 hours.

I do not believe promiscusous mode matters when the card is in monitor mode.

I used a Netgear MA-402 Ap and MA401 pcmica card and captured about 70 
mb of packets with weak iv's.  It took dwepcrack about 30 seconds to 
load the packets and 3 seconds to crack the WEP key.

Tye
