Thread: 4-Way Handshake vs PMKID
Post: RE: 4-Way Handshake vs PMKID
1. Calculating of PMKID is faster
PMKID = HMAC-SHA1-128(PMK, "PMK Name" | MAC_AP | MAC_STA)
2. You run hashcat with default nonce-error-corrections on WPA-EAPOL-PBKDF2, so every md5 (WPA1) or sha ... |

Thread: 4-Way Handshake vs PMKID
Post: RE: 4-Way Handshake vs PMKID
As Atom said, PBKDF2 will cost us much time!
Now we drop PBKDF2:
$ time hashcat -m 2501 test.hccapx --nonce-error-corrections=0 foundhashcat.pmk
hashcat (v5.1.0-855-g9ced13cc) starting...

Thread: PBKDF2 and SHA-1 question

You are right, hashcat is using OpnCl for both functions. The c code example should show that the functions are easy to implement in different coding languages like c, by adding cryptolibs.

Thread: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats
Post: RE: hcxtools - solution for capturing wlan traffic...
You can retrieve a PSK or a PMK only from a weak client. Therefore you must run hcxdumptool over a long time against your penetration target.
We can not distinguish between an ESSID, a damaged ESSID,... |

And this is really important:
Hashmodes 2501 and 16801 are not cracking hashmodes.
The are only usefull to verfify(!) an existing PMK. |

Yes, wpa_supplicant and hostapd are amazing open source tools. I really love them both and they are an integral part of my test environment to improve hcxdumptool. |
