Clean up CAP and Convert to HCCAPX for use with Hashcat:   Crack WPA Handshake with Hashcat using Wordlist

Open captured handshake file with Wireshark and apply the following filter.

eapol || wlan.fc.type_subtype == 0x04 || wlan.fc.type_subtype == 0x08  <--- Wireshark Filter
    > Filter Out Complete 4 way Handshake using Wireshark
    > Using right click menu mark the 4 handshake packets aswell as the top broadcast packet
       - then export. File > Export > Select Marked Packets and save with .cap file extension
      
After cleaning up the .CAP handshake and exporting you must convert it for use with Hashcat
    > Use https://hashcat.net/cap2hccapx/ to convert from .CAP to .HCCAPX
    
Ready to start cracking using Hashcat. Open a CMD or Terminal prompt, run as Admin/Root and issue the following command (I used windows version of Hashcat hints the .exe in the below hashcat command)
    > hashcat64.exe -m 2500 CapturedHandshake.hccapx wordlists/rockyou.txt
    
    
NOTES:
    When cleaning up CAP file with Wireshark you want to make sure that you
    select the correct packets. There will be 5 selected packets in total
    Here is what the finished Wireshark output will look like if done properly

    No.  Tine                  Source            Destination         Protocol      Length       Info

    1  0.000000        Actionte_29:79:75     Broadcast                802.11        261       Beacon frame, SN=2579,  FN=0,  Flags= ........ , BI=100, SSID=NAMEofWIFI
    2 141.783428     Actionte_29:79:75     Apple_59:67:41      EAPOL         155       Key (Message 1 of 4)
    3 141.810056     Apple_59:67:41        Actionte_29:79:75   EAPOL         155       Key (Message 2 of 4)
    4 141.822340     Actionte_29:79:75     Apple_59:67:41      EAPOL         213       Key (Message 3 of 4)
    5 141.825929     Apple_59:67:41        Actionte_29:79:75   EAPOL         133       Key (Message 4 of 4)

    
    I believe the Key Message packets 1 thru 4 must be in order starting at 1 and ending in 4.
    You cannot select the packets out of order or it will not work

This is a quick write up that I hope will help some people who are having trouble. I also hope that im not reposting something that has already been covered multiple times.  Like i said i hope this helps out
