Description:

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 backend 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

Supported EAP methods (IEEE 802.1X Supplicant):
* EAP-TLS
* EAP-PEAP/MSCHAPv2 (both PEAPv0 and PEAPv1)
* EAP-PEAP/TLS (both PEAPv0 and PEAPv1)
* EAP-PEAP/GTC (both PEAPv0 and PEAPv1)
* EAP-PEAP/OTP (both PEAPv0 and PEAPv1)
* EAP-PEAP/MD5-Challenge (both PEAPv0 and PEAPv1)
* EAP-TTLS/EAP-MD5-Challenge
* EAP-TTLS/EAP-GTC
* EAP-TTLS/EAP-OTP
* EAP-TTLS/EAP-MSCHAPv2
* EAP-TTLS/EAP-TLS
* EAP-TTLS/MSCHAPv2
* EAP-TTLS/MSCHAP
* EAP-TTLS/PAP
* EAP-TTLS/CHAP
* EAP-SIM
* EAP-AKA
* EAP-PSK (experimental)
* EAP-FAST
* EAP-PAX (experimental)
* LEAP (note: requires special support from the driver)

Following methods are also supported, but since they do not generate
keying material, they cannot be used with WPA or IEEE 802.1X WEP
keying.
* EAP-MD5-Challenge
* EAP-MSCHAPv2
* EAP-GTC
* EAP-OTP

More information about EAP methods and interoperability testing is
available in eap_testing.txt.
