4-Way Handshake vs PMKID
#6
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 (WPA2)
or aes (WPA2 key ver 3) calculation is performed 8 times for big endian and little endian anonces.
If you are sure your captured handshake is ok, run --nonce-error-corrections=0
that will make hashcat faster

$ time hashcat -m 2500 test.hccapx --nonce-error-corrections=128 digit20
hashcat (v5.1.0-855-g9ced13cc) starting...

real 0m15,633s
user 0m7,852s
sys 0m1,074s

$ time hashcat -m 2500 test.hccapx --nonce-error-corrections=0 digit20
hashcat (v5.1.0-855-g9ced13cc) starting...

real 0m11,981s
user 0m7,643s
sys 0m0,909s

use time to calculate the real time:

and to retrieve real(!) values of execution time
