Hi all,

A new tool, to analyze and crack WEP encryption (both 64 and 128 keys), has just been released. It implements the FMS attack but with some optimizations (h1kari ones) not present in wepcrack or airsnort. I guess some of you will find it quite useful

The name of the tool is weplab. You can find it in http://www.sourceforge.net/projects/weplab

Weplab is tested on GNU/Linux with latest version of libpcap. Please take a look at the scripts in the CVS to place your prism2 in monitor mode, so weplab is able to capture packets.

Please note that it is still in alpha stage, but stills it manages to product positive results with more than 1.5M normal (not necessary "classic" weak packets). For example my 64 bits keys gets cracked after 40 minutes with 2M packets and my 128 bits key falls with just 1M packets. I need some feedback to tune the cracking parameters.
