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 and John the Ripper git.

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

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

Support of gzip (.gz) single file compression.

Main purpose is to detect weak points within own WiFi networks by analyzing the hashes. Therefore convert the dump file to WPA-PBKDF2-PMKID+EAPOL hash file and check if wlan-key or plainmasterkey was transmitted unencrypted. Or upload the "uncleaned" dump file (pcapng, pcap, cap) here to find out if your ap or the client is vulnerable by using common wordlists or a weak password generation algorithm.

Brief description

Multiple stand-alone binaries - designed to run on Arch Linux, but other Linux distributions should work, too.

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

Detailed description

Tool Description
hcxpcapngtool Provide new hashcat format 22000
hcxhashtool Provide various filter operations on new PMKID/EAPOL hash line
hcxpsktool Calculates candidates for hashcat and john based on based on hcxpcapngtool output or commandline input
hcxpmktool Calculate and verify a PSK and/or a PMK
hcxeiutool Prepare -E -I -U output of hcxpcapngtool for use by hashcat + rule or JtR + rule
hcxwltool Calculates candidates for hashcat and john based on mixed wordlists
hcxhash2cap Converts hash file (PMKID&EAPOL, PMKID, EAPOL-hccapx, EAPOL-hccap, WPAPSK-john) to cap
wlancap2wpasec Upload multiple (gzip compressed) pcapng, pcap and cap files to
whoismac Show vendor information and/or download oui reference list


hcxdumptool -> hcxpcapngtool -> hcxhashtool (additional hcxpsktool/hcxeiutool) -> hashcat or JtR

hcxdumptool: attack and capture everything (depending on options)

hcxpcapngtool: convert everything

hcxhashtool: filter hashes

hcxpsktool: get weak PSK candidates

hcxeiutool: calculate wordlists from ESSID

hashcat or JtR: get PSK from hash

Get source

git clone
cd hcxtools


make install (as super user)

Or install via packet manager of your distribution

Arch Linux pacman -S hcxtools

Arch Linux ARM

Arch Linux ARM pacman -S hcxtools


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


dnf install hcxtools

  • knowledge of radio technology
  • knowledge of electromagnetic-wave engineering
  • detailed knowledge of 802.11 protocol
  • detailed knowledge of key derivation functions
  • detailed knowledge of Linux
  • Linux (recommended Arch Linux, but other distros should work, too (no support for other distributions).
  • gcc >= 11 recommended (deprecated versions are not supported:
  • libopenssl (>= 3.0) 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 (>= 7.56) and curl-dev installed (used by whoismac and wlancap2wpasec)
  • pkg-config installed

Debian (e.g. Kali, Ubuntu) release requirements >= bookworm (testing/Debian 12)
To install use the following:
apt-get install pkg-config libcurl4-openssl-dev libssl-dev zlib1g-dev make gcc

If you decide to compile latest git head, make sure that your distribution is updated on latest version.

Useful scripts

Script Description
piwritecard Example script to restore SD-Card
piwreadcard Example script to backup SD-Card Extract records from m22000 hashline/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)

hcxtools are designed to be analysis tools. This means that everything is converted by default and unwanted information must be filtered out!

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
