In this article, we’ll delve into the world of Wi-Fi hacking, exploring the methods and tools used to crack Wi-Fi passwords. But before we dive in, let’s emphasize that hacking is illegal and unethical unless you have explicit permission from the network owner.
The Anatomy of Wi-Fi Passwords
Before we discuss how to hack Wi-Fi passwords, it’s essential to understand how they work. Wi-Fi passwords, also known as WEP/WPA/WPA2 keys, are used to secure wireless networks. There are two primary types of Wi-Fi passwords:
WEP (Wired Equivalent Privacy)
WEP is an older encryption protocol introduced in 1997. It uses a 40-bit or 104-bit key to encrypt data transmitted over the network. Although WEP was widely used in the past, it’s now considered insecure and easily crackable.
WPA/WPA2 (Wi-Fi Protected Access)
WPA and WPA2 are newer encryption protocols, introduced in 2003 and 2004, respectively. They use a 128-bit or 256-bit key to encrypt data, making them much more secure than WEP. WPA2 is the currently recommended encryption protocol for securing Wi-Fi networks.
