A single BEACON and a single M1 (with PMKID) or a single message pair (M1M2, M2M3, M3M4 not zeroed SNONCE, M1M4 not zeroed SNONCE) is is far from enough to retrieve all this information!
Due to my analysis of dump files submitted to wpa-sec, I noticed many dump files which doesn't contain important frames. Either this frames are not stored by the dump tool or they have been removed/cleaned by the submitter. That will make it hard to recover the PSK.
tshark is a very good tool, to retrieve all information on the command line. If you prefer a GUI, you can use Wireshark.
Hash formats 1680x and 250x (hccapx) only contain pure information, required to recover the PSK.
BTW:
And example, what you're missing on a cleaned dump file or a dump file which doesn't contain this frames is here:
https://hashcat.net/forum/thread-6661-post-47500.html#pid47500
1680x and 250x will be deprecated as soon as release of hashcat 6.0.0
Successor is the new hashline/hashmode 22000, which will give you full advantage of reuse of PBKDF2 over PMKID and EAPOL.
Thank you very much for in-depth reply. This is really helpful.
I knew about tshark and wireshark. I was hoping that there was simpler way
Thanks again !!!

tshark can do this really good:
$ tshark -r test.pcapng.cap -T fields -e wps.device_name -e wps.serial_number
or (inclusive transmitter address and ESSID):
$ tshark -r test.pcapng.cap -T fields -e wlan.ta -e wlan.ssid -e wps.device_name -e wps.serial_number
You can save them via stdout and validate them via bash commands with hcxhastool output.

updated to latest (after not updating 6 months or so) and I notice that when running latest hcxdumptool
- there is no more status line at the bottom which states how many handshakes have been captured anymore
- less items (status updates) on display than before ?
am running hcxdumptool with --enable_status=15, should this be changed to something else ?
anyway Zerbea, thanks for all your work in updating and adding new features to this tool.
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ZerBea - 02-11-2020
We are using a bitmask:
Code:
--enable_status=<digit> : enable real-time display (waterfall)
some messages are shown only once at the first occurrence
bitmask:
0: no status (default)
1: EAPOL
2: PROBE REQUEST/PROBE RESPONSE
4: AUTHENTICATON
8: ASSOCIATION/REASSOCIATION
16: BEACON
32: GPS (once a minute)
64: internal status
128: run as server
256: run as clientTo retrieve the status add 64!

Hi ZerBea
Just thought I would let you know I am still watching your progress on GitHub as you tweak your code!
I am slowly working through the questions I have myself and look forward to the day hcx-anything replaces pretty much all other wifi tools.
Great work and thank you for sharing.

I'll do my very best.

Feedback appreciated regarding this commit:
https://github.com/ZerBea/hcxdumptool/commit/6c98258c437b205810fd496d37495e2d48e02cc5
Target: AP with activated Management Frame Protection (MFP) and (if possible) deactivated PMKID caching and connected CLIENT(s)
$ hcxdumptool -i interface --enable_status=63 --reactive_beacon -c working_channel_of_AP
expected result:
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx REASSOCIATION (NETWORKNAME)
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx MP:M1M2 RC:x EAPOLTIME:xxxxx (NETWORKNAME)
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx MP:M2M3 RC:x EAPOLTIME:xxxxx (NETWORKNAME)
or
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx REASSOCIATION (NETWORKNAME)
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx MP:M1M2 RC:xxxxx EAPOLTIME:xxxxx (NETWORKNAME)
or
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx REASSOCIATION (NETWORKNAME)
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx MP:M1M2 RC:xxxxxx EAPOLTIME:xxxxx (NETWORKNAME)
12:16:18 6 xxxxxxxxxxxx <-> xxxxxxxxxxxx MP:M2M3 RC:x EAPOLTIME:xxxxx (NETWORKNAME)
or any combination of this message pairs.
For this test, it is important that the CLIENT is connected before hcxdumtool starts. Only then MFP is active.
If it isn't possible to deactivate PMKID caching, it is very likely that hcxdumptool got a PMKID before MFP is active and stops the attack. In that case please retry it.
Requesting a PMKID is much faster than retrieving a full 4-way handshake.

I am impressed with the new vector, you are really pushing forward on all possibilities.
The more I learn about this subject the more I realise I am not qualified to have any opinion!
However I think the first option looks OK to me.
hcx- is just getting better and better!

There are no(!) errors:

INFO ERROR:0 that means no device ERROR

we possible miss the interface statistic block at the end of the cap file.
RT8812AU and RTL8188EU are under maintenance and there are many issues. Christian (kimocoder) doing a great job here:
https://github.com/aircrack-ng/rtl8812au/issues
https://github.com/aircrack-ng/rtl8188eus/issues
Unfortunately he is a little bit busy.
Unfortunately both drivers require iw (running NETLINK) to set monitor mode.
hcxdumptool use ioctl() and AF_PACKET instead of adding another dependency to the attack vector. That is much, much faster than a virtual NETLINK interface!
BTW:
hcxpcaptool is deprecated. Please use hcxpcapngtool!
RE: hcxtools - solution for capturing wlan traffic and conversion to hashcat formats - ciccio17 - 02-23-2020
hi zerbea, i'm back, long time now, hope everythink is ok for you. i have some question.
is the bug with ath9k-htc resolved? also is this problem the same on ath9k non usb card, i use hcxdumptool on openwrt in general? also i'm still on version 5 of your tools, and still on stable hashcat 5.1.
so should i stay on this old tools or just use the new one with my hardware and hashcat 5.1 version?
also is usable the tool on linux kernel 5.4.x?
i used your last git on kernel 4.19 and is totaly a different tool for me,
thank you for you work.
