How to identify and crack a WPA/WPA2 EAPOL handshake (22000) hash

WPA/WPA2 EAPOL handshake (22000) is a network authentication hash type. It is fast and typically unsalted, which makes weak passwords recoverable quickly on consumer GPU hardware. This page shows how to recognise it and the exact commands to attack it.

All identification runs locally in WebAssembly. The commands below write the hash to a local file on your machine — nothing is sent to this site.

Identifying the hash

The hash identifier on the home page detects WPA/WPA2 EAPOL handshake (22000) entirely in your browser — your hash is never uploaded. A typical example looks like this:

WPA*01*4d4fe7a...*0242ac...*...

Cracking WPA/WPA2 EAPOL handshake (22000) with hashcat

Save the hash to a file and run hashcat in mode -m 22000. Start with a wordlist such as rockyou.txt:

echo 'WPA*01*4d4fe7a...*0242ac...*...' > hash.txt && hashcat -m 22000 hash.txt /usr/share/wordlists/rockyou.txt

Add a rule set to mutate dictionary words (capitalisation, leetspeak, appended digits) and dramatically widen coverage:

echo 'WPA*01*4d4fe7a...*0242ac...*...' > hash.txt && hashcat -m 22000 hash.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule

Cracking WPA/WPA2 EAPOL handshake (22000) with John the Ripper

John the Ripper can attack the same hash with the wpapsk format:

echo 'WPA*01*4d4fe7a...*0242ac...*...' > hash.txt && john --format=wpapsk --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
