wpa_supplicant is a WPA Supplicant for Linux, BSD and Windows with
support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE
802.1X/WPA component that is used in the client stations. It
implements key negotiation with a WPA Authenticator and it controls
the roaming and IEEE 802.11 authentication/association of the wlan
driver.

wpa_supplicant is designed to be a "daemon" program that runs in the
background and acts as the back-end component controlling the wireless
connection. wpa_supplicant supports separate frontend programs and an
example text-based frontend, wpa_cli, is included with wpa_supplicant.

Supported WPA/IEEE 802.11i features:
* WPA-PSK ("WPA-Personal")
* WPA with EAP (e.g., with RADIUS authentication server)
("WPA-Enterprise")
* key management for CCMP, TKIP, WEP104, WEP40
* WPA and full IEEE 802.11i/RSN/WPA2
* RSN: PMKSA caching, pre-authentication

list of supported EAP methods (IEEE 802.1X Supplicant), supported
drivers and interoperability testing.
