Cracking WPA/WPA2 hashes

Handshake .cap

To crack WPA/WPA2 handshakes from a .cap file using Hashcat, you can use the following command:

hashcat -m 2500 (or 22000) capture.hccapx wordlist.txt

For this, you need to convert the .cap file to the .hccapx format first, which can be done using tools like cap2hccapx.

For John the Ripper, the command would look like:

john --wordlist=wordlist.txt --format=wpapsk capture.hccapx

John the Ripper also requires the handshake to be in a specific format, often a converted .hccapx or directly in John's own 'netntlm' format.

aircrack-ng -a 2 -w /usr/share/dict/wordlist-probable.txt --bssid CC:D0:83:70:22:E2 -l /tmp/wifitejrkm_0dh/wpakey.txt hs/handshake_wifi13-43-05.cap

PMKID hash

To crack a PMKID hash, you can use the following command for Hashcat:

hashcat -m 16800 pmkid_hash.txt wordlist.txt

Here, -m 16800 specifies the hash type for PMKID, pmkid_hash.txt is the file containing the captured PMKID hash, and wordlist.txt is your wordlist.

For John the Ripper, you'd first convert the PMKID hash into a format John can understand using hcxpcaptool or a similar conversion utility. Then, you can crack it using:

john --format=wpapsk pmkid_john_hash.txt

Here, --format=wpapsk specifies the hash type, and pmkid_john_hash.txt would be the John-readable hash.
