## aircrack-ng principle ：

0x02:aircrack-ng Simple use

aircrack-ng It's usually used to recover WEP,WPA-PSK Password , Through the collection of previous traffic packets , Can be used to crack packets .
Use before passing wireshark Collected traffic packets , Cooperate with the code of blasting , You can parse the packets .
Simple use case ： Experiment topic ——A Record
1. Download to get traffic , use first aircrack-ng Check the flow package ：

Information can be obtained from is used wpa encryption .
2. Use the weak password dictionary to run the password .

aircrack-ng shipin.cap -w wordlist.txt

3. Got the code is 88888888. Use what you just got SSID And password to decode it

airdecap-ng shipin.cap -e 0719 -p 88888888

4. Open the newly generated cap package , lookup dns Just flow .

aircrack-ng This is not the only function of , It can be done by analyzing the flow comparison WiFi Crack , monitor ,AP Forgery, etc .
