features

this project is available in French: all thanks goto Matt² for his excellent translation!
sorts targets by power (in dB); cracks closest access points first
automatically deauths clients of hidden networks to decloak SSIDs
numerous filters to specify exactly what to attack (wep/wpa/both, above certain signal strengths, channels, etc)
customizable settings (timeouts, packets/sec, channel, change mac address, ignore fake-auth, etc)
"anonymous" feature; changes MAC to a random address before attacking, then changes back when attacks are complete
all WPA handshakes are backed up to wifite.py's current directory
smart WPA deauthentication -- cycles between all clients and broadcast deauths
stop any attack with Ctrl+C -- options: continue, move onto next target, skip to cracking, or exit
switching WEP attack methods does not reset IVs
intel 4965 chipset fake-authentication support; uses wpa_supplicant workaround
SKA support (untested)
displays session summary at exit; shows any cracked keys
all passwords saved to log.txt
built-in updater: ./wifite.py -upgrade

aircrack-ng (v1.1) suite: available via apt: apt-get install aircrack-ng or by clicking here,
xterm, python-tk module: required for GUI, available via apt: apt-get install python-tk
macchanger: also available via apt: apt-get install macchanger
pyrit: not required, optionally strips wpa handshake from .cap files
