About WepDecrypt: Wepdecrypt is a Wireless LAN Tool written in c which guesses WEP Keys based o

These are some examples of a creative usage of the tools found in wepdecrypt.
This one is a modified version of wepdecrypt_word script that uses plain words found in 
the dump file to build a dictionary, made by Scott Taylor <[e-mail]>
