How to reduce WPA(2) capture file size

Source are available on github: hcxtools.
There are no binaries at this time you can download, so you will need to compile the tool: simply make.

hcxpcaptool shows info of pcap/pcapng file and convert it to other hashformats accepted by hashcat and John the Ripper. It converts AND clean your file:

./hcxpcaptool -o new.hccapx original_file.cap

More options can be used:

options:
-o  : output hccapx file (hashcat -m 2500/2501)
-O  : output raw hccapx file (hashcat -m 2500/2501)
-x  : output hccap file (hashcat -m 2500)
-X  : output raw hccap file (hashcat -m 2500)
-z  : output PMKID file (hashcat hashmode -m 16800)
-Z  : output PMKID file (hashcat hashmode -m 16801)
-j  : output john WPAPSK-PMK file (john wpapsk-opencl)
-J  : output raw john WPAPSK-PMK file (john wpapsk-opencl)
-E  : output wordlist (autohex enabled) to use as input wordlist for cracker
-I  : output unsorted identity list
-U  : output unsorted username list
-P  : output possible WPA/WPA2 plainmasterkey list
-T  : output management traffic information list
          : european date : timestamp : mac_sta : mac_ap : essid
-H  : output dump raw packets in hex
-V        : verbose (but slow) status output
-h        : show this help
-v        : show version

--time-error-corrections=  : maximum allowed time gap (default: 600s)
--nonce-error-corrections= : maximum allowed nonce gap (default: 8)
                                  : should be the same value as in hashcat
--netntlm-out=              : output netNTLMv1 file (hashcat -m 5500, john netntlm)
--md5-out=                  : output MD5 challenge file (hashcat -m 4800)
--md5-john-out=             : output MD5 challenge file (john chap)
--tacacsplus-out=           : output TACACS+ authentication file (hashcat -m 16100, john tacacs-plus)

bitmask for message pair field:
0: MP info (https://hashcat.net/wiki/doku.php?id=hccapx)
1: MP info (https://hashcat.net/wiki/doku.php?id=hccapx)
2: MP info (https://hashcat.net/wiki/doku.php?id=hccapx)
3: x (unused)
4: ap-less attack (set to 1) - no nonce-error-corrections neccessary
5: LE router detected (set to 1) - nonce-error-corrections only for LE neccessary
6: BE router detected (set to 1) - nonce-error-corrections only for BE neccessary
7: not replaycount checked (set to 1) - replaycount not checked, nonce-error-corrections definitely neccessary

Do not use hcxpcaptool in combination with third party cap/pcap/pcapng cleaning tools!

As said, "Do not use hcxpcaptool in combination with third party cap/pcap/pcapng cleaning tools!"

Once done you can upload the converted file to our website.
