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