wpa_supplicant is a free software implementation of an IEEE 802.11i supplicant for Linux, FreeBSD, NetBSD, AROS, Microsoft Windows, Solaris, OS/2 (including eComStation) and Haiku. In addition to being a fully featured WPA2 supplicant, it also implements WPA and older wireless LAN security protocols. Features include:

  • WPA and full IEEE 802.11i/RSN/WPA2
  • WPA-PSK and WPA2-PSK ("WPA-Personal", pre-shared key)
  • WPA with EAP ("WPA-Enterprise", for example with RADIUS authentication server)
  • key management for CCMP, TKIP, WEP (both 104/128- and 40/64-bit)
  • RSN: PMKSA caching, pre-authentication

Included with the supplicant are a GUI and a command-line utility for interacting with the running supplicant. From either of these interfaces it is possible to review a list of currently visible networks, select one of them, provide any additional security information needed to authenticate with the network (for example, a passphrase, or username and password) and add it to the preference list to enable automatic reconnection in the future.[2]

The graphical user interface is built on top of the Qt library.

EAP methods[edit]

wpa_supplicant can authenticate with any of the following EAP (Extensible Authentication Protocol) methods:[2]
