This way ALFA card allows us to monitor all of the wireless traffic that pass through the air. This is the same way we put a wired adapter into promiscuous mode. Now first will start our wireless adapter in monitor mode. In this article will use ALFA Network Card as a WIFI Adapter. Let’s Start with Step by Step Let’s start Wi-Fi Adapter in Monitor Mode with Airmon-Ng
#WPA2 HASH ALGORITHM PASSWORD#
If we can grab the password at that time, we can then attempt to crack it. Here, when a client (User) authenticates to the access point (AP), the client and the AP go through a 4-step process to authenticate the user to the AP.
Researchers found that the weakness in the WPA2-PSK system is that the encrypted password is shared in what is known as the 4-way handshake. This is stronger encryption algorithm, AES, that is very difficult to crack-but not impossible. However, nowadays WEP encryption is terribly flawed and easily cracked.Īs a replacement of WEP (Wired Equivalent Privacy) encryption, most of the wireless access points use Wi-Fi Protected Access II with a pre-shared key for wireless security, which also known as WPA2-PSK. Wi-Fi was first developed in the late 1990s, with WEP encryption which stands for Wired Equivalent Privacy this was created to give wireless communications privacy and confidentiality.
If you want to secure 100% wireless network, then the best method is to disable wireless, but if you use it, then you cannot. In this article will learn how you can crack WPA2 encryption password file.
