The Transmission Control Protocol (TCP) handshake

Also known as a three-way handshake, this requires the two hosts to be synchronized with each other's initial sequence number (ISN) for a connection to be established, before data transfer begins. The need for us to obtain a TCP handshake is because the hash (a hash is a string or number generated from a string of plain text) is stored within the SYN/ACK packet:

You can use the following command to send a deauthentication to the AP: aireplay-ng --deauth 10 -a 02:13:37:A5:99:E3 -c 10:03:cd:04:06:fe wlan0mon:

--deauth 10 means sending 10 packets to deauthenticate that device
-a is the target device (your Wi-Fi router)
-c is the connected station (connected device on the network):

You're doing this to recapture the TCP handshake, which will be saved in your CrackWPA file:

Now clean it of any unneeded data, and convert it to run with hashcat:

Get into your root and type: cp CrackWPA-01.cap /root/Desktop/.
Copy files to the directory you specify.
