Which of the following tools from Aircrack-ng Suite decrypts WEP/WPA/WPA2 and strips wireless headers from Wi-Fi packets?

Aircrack-ng
Airdecap-ng
Aireplay-ng
Airodump-ng

The correct answer is: Airdecap-ng

The choice of Airdecap-ng as the correct answer is based on its specific functionality within the Aircrack-ng Suite. Airdecap-ng is designed to decrypt WEP (Wired Equivalent Privacy) and WPA/WPA2 (Wi-Fi Protected Access) encrypted packets, which is essential for analyzing and understanding wireless traffic that has been secured by these protocols. In addition to decryption, Airdecap-ng also strips unnecessary headers from Wi-Fi packets, making the data more manageable and focused for further analysis. This process is particularly useful for security professionals and ethical hackers who need to scrutinize the contents of the packets without the extra layers of data that can complicate analysis. The other tools in the Aircrack-ng Suite serve different purposes. For example, Airodump-ng is primarily used for packet capturing and monitoring wireless networks, Aireplay-ng is focused on injecting packets to generate traffic, and Aircrack-ng is the tool that specifically cracks the captured pre-shared keys or WEP keys after those have been obtained. Each of these tools plays a critical role in the suite, but Airdecap-ng's unique ability to handle decryption and header stripping positions it as the correct choice for this particular function.
