Wpa supplicant
Open-source implementation of IEEE 802.11i From Wikipedia, the free encyclopedia
wpa_supplicant is a free software implementation of an IEEE 802.11i supplicant for Linux, FreeBSD, NetBSD, QNX, AROS, Microsoft Windows, Solaris, OS/2 (including ArcaOS and eComStation)[2] and Haiku.[3] In addition to being a WPA3 and WPA2 supplicant, it also implements WPA and older wireless LAN security protocols.

Features
Features include:[4]
- WPA-PSK and WPA2-PSK ("WPA-Personal", pre-shared key)
- WPA3[5]
- WPA with EAP ("WPA-Enterprise", for example with RADIUS authentication server)
- RSN: PMKSA caching, pre-authentication
- IEEE 802.11r
- IEEE 802.11w
- Wi-Fi Protected Setup (WPS)
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.[6]
The graphical user interface is built on top of the Qt library.
wpa_supplicant can authenticate with any of the following EAP (Extensible Authentication Protocol) methods: EAP-TLS, EAP-PEAP (both PEAPv0 and PEAPv1), EAP-TTLS, EAP-SIM, EAP-AKA, EAP-AKA', EAP-pwd, EAP-EKE, EAP-PSK (experimental), EAP-FAST, EAP-PAX, EAP-SAKE, EAP-GPSK, EAP-IKEv2, EAP-MD5, EAP-MSCHAPv2, and LEAP (requires special functions in the driver).[6]
Vulnerability to KRACK
wpa_supplicant was especially susceptible to KRACK, as it can be manipulated to install an all-zeros encryption key, effectively nullifying WPA2 protection in a man-in-the-middle attack.[7] Version 2.7 fixed KRACK and several other vulnerabilities.
