Introduction
dweputils is a set of utilities that allows you to fully audit and secure a wep encrypted network. it consists of a packet collection tool called dwepdump, which allows you to collect wep encrypted packets using a prism2 card, as well as dwepcrack which allows you to recover wep keys using any of the commonly used methods, and dwepkeygen a secure 40-bit key generator that creates keys that aren't vulnerable to the Tim Newsham 2^21 attack using a variable length seed. These tools also include support for some of the new methods outlined in "Practical Exploitation of RC4 Weaknesses in WEP Environments".
By utilizing the outlined methods, it can generally recover wep keys with only around 2,000,000-500,000 packets in < 1 minute on most machines, although with some networks results may vary.
