Small set of tools convert packets from captures (h = hash, c = capture, convert and calculate candidates, x = different hashtypes) for the use with latest hashcat or John the Ripper. The tools are 100% compatible to hashcat and John the Ripper and recommended by hashcat. This branch is pretty closely synced to hashcat git branch (that means: latest hcxtools matching on latest hashcat beta) and John the Ripper git branch ("bleeding-jumbo").

Support for hashcat hash-modes: 4800, 5500, 2200x, 16100, 250x (deprecated), 1680x (deprecated)

Support for John the Ripper hash-modes: WPAPSK-PMK, PBKDF2-HMAC-SHA1, chap, netntlm, tacacs-plus

After capturing, upload the "uncleaned" cap here ( to see if your ap or the client is vulnerable by using common wordlists. Convert the dump file to WPA-PBKDF2-PMKID+EAPOL hash file and check if wlan-key or plainmasterkey was transmitted unencrypted.

Brief description

Multiple stand-alone binaries - designed to run on Arch Linux.

All of these utils are designed to execute only one specific function.

hcxdumptool moved to:

Get source

git clone
cd hcxtools


make install (as super user)

Or install via packet manager of your distribution

Arch Linux

Arch Linux pacman -S hcxtools

Arch Linux ARM

Arch Linux ARM pacman -S hcxtools

Black Arch

Black Arch is an Arch Linux-based penetration testing distribution for penetration testers and security researchers
pacman -S hcxtools

Kali Linux

apt install hcxtools


Homebrew is 3-rd party package manager for macOS
brew install hcxtools


  • Linux (recommended Arch Linux, but other distros should work, too (no support for other distributions).

  • gcc 10 recommended (deprecated versions are not supported:

  • libopenssl and openssl-dev installed

  • librt and librt-dev installed (should be installed by default)

  • zlib and zlib-dev installed (for gzip compressed cap/pcap/pcapng files)

  • libcurl and curl-dev installed (used by whoismac and wlancap2wpasec)

  • libpthread and pthread-dev installed (used by hcxhashcattool)

  • pkg-config installed

To install requirements on Kali use the following 'apt-get install pkg-config libcurl4-openssl-dev libssl-dev zlib1g-dev'

Useful scripts

Script Description
piwritecard Example script to restore SD-Card
piwreadcard Example script to backup SD-Card Extract records from hccapx/pmkid file based on regexp


Most output files will be appended to existing files (with the exception of pcapng, pcap, cap files).

It is recommended to use hash mode 22000 (22001) instead of deprecated hash modes 2500 (2501) and 16800 (16801)

Bitmask message pair field (hcxpcapngtool)

bit 0-2

000 = M1+M2, EAPOL from M2 (challenge)

001 = M1+M4, EAPOL from M4 if not zeroed (authorized)

010 = M2+M3, EAPOL from M2 (authorized)

011 = M2+M3, EAPOL from M3 (authorized) - unused"

100 = M3+M4, EAPOL from M3 (authorized) - unused"

101 = M3+M4, EAPOL from M4 if not zeroed (authorized)"

3: reserved

4: ap-less attack (set to 1) - no nonce-error-corrections necessary

5: LE router detected (set to 1) - nonce-error-corrections only for LE necessary

6: BE router detected (set to 1) - nonce-error-corrections only for BE necessary

7: not replaycount checked (set to 1) - replaycount not checked, nonce-error-corrections definitely necessary
