<application>WPA Supplicant</application> is a Wi-Fi Protected Access
|
|
(WPA) client and IEEE 802.1X supplicant. It implements WPA key negotiation
|
|
with a WPA Authenticator and Extensible Authentication Protocol (EAP)
|
|
authentication with an Authentication Server. In addition, it controls the
|
|
roaming and IEEE 802.11 authentication/association of the wireless LAN
|
|
driver. This is useful for connecting to a password protected wireless
|
|
access point.
