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.
wpa_supplicant and hostapd come as a pair of complementary client and host for wireless access points. That is hostapd allows us to create access points from the command line, which allows one to share one's internet connection wirelessly, while wpa_supplicant allows us to scan and to connect to access points as a client in order to get onto ...
A Wireless Supplicant is a program that runs on a computer and is responsible for making login requests to a wireless network. [1] It handles passing the login and encryption credentials to the authentication server. It also handles roaming from one wireless access point to another, in order to maintain connectivity.
802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server. The supplicant is a client device (such as a laptop) that wishes to attach to the LAN/WLAN. The term 'supplicant' is also used interchangeably to refer to the software running on the client that provides credentials to the authenticator.
The IEEE 802.1X standard [1] uses the term "supplicant" to refer to either hardware or software. In practice, a supplicant is a software application installed on an end-user's computer. The user invokes the supplicant and submits credentials to connect the computer to a secure network. If the authentication succeeds, the authenticator typically ...
Xsupplicant up to version 1.2.8 was designed to run on Linux clients as a command line utility. Version 1.3.X and greater are designed to run on Windows XP and are currently being ported to Linux/BSD systems, and include a robust graphical user interface, and also includes network access control (NAC) functionality from Trusted Computing Group's Trusted Network Connect NAC.
Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs.It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic.
WPA-Personal and WPA2-Personal remain vulnerable to password cracking attacks if users rely on a weak password or passphrase. WPA passphrase hashes are seeded from the SSID name and its length; rainbow tables exist for the top 1,000 network SSIDs and a multitude of common passwords, requiring only a quick lookup to speed up cracking WPA-PSK.
