7 WPA/WPA2 Security

wpa_supplicant is a user space program used to set and manage wireless connections secured

through WPA/WPA2 both Personal and Enterprise. All the parameters used to secure the wifi

connection can be set into /etc/wpa_supplicant.conf configuration file.

wpa_supplicant can be simply run through a command shell.

wpa_supplicant implements a control interface that can be used by external programs such as wpa_cli

to control the operations of the wpa_supplicant itself and to get status information and event

notifications.

For further information about wpa_supplicant supported WPA/IEEE 802.11i features and Enterprise

modes please have a look to paragraph 8.2.

Please have a look to paragraph 1.4.2 for information about wpa_supplicant/wpa_cli License.
