Convert error
#1
Hello All,

I have obtained the handshake and when trying to convert with the HashCat Converter tool I get the following error:
"(PMK not recoverable)" and thus no file is generated.. 

Help with this is appreciated. 
Handshake extraction failed!

Information: no hashes written to hash files

Information: limited dump file format detected!
This file format is a very basic format to save captured network data.
It is recommended to use PCAP Next Generation dump file format (or pcapng for short) instead.
The PCAP Next Generation dump file format is an attempt to overcome the limitations
of the currently widely used (but very limited) libpcap (cap, pcap) format.

Information: radiotap header is missing!
Radiotap is a de facto standard for 802.11 frame injection and reception.
The radiotap header format is a mechanism to supply additional information about frames,
from the driver to userspace applications.

Warning: too many deauthentication/disassociation frames detected!
That can cause that an ACCESS POINT change channel, reset EAPOL TIMER,
renew ANONCE and set PMKID to zero.
This could prevent to calculate a valid EAPOL MESSAGE PAIR
or to get a valid PMKID.

Information: missing frames!
This dump file does not contain undirected proberequest frames.
An undirected proberequest may contain information about the PSK.
It always happens if the capture file was cleaned or
it could happen if filter options are used during capturing.
That makes it hard to recover the PSK.

Information: missing frames!
This dump file does not contain enough EAPOL M1 frames.
It always happens if the capture file was cleaned or
it could happen if filter options are used during capturing.
That makes it impossible to calculate nonce-error-correction values.

You're trying to convert a sae256/wpa3 handshake.
Code:
ASSOCIATIONREQUEST (SAE SHA256)..........: 1
There is no hash mode in hashcat to recover a sae256/wpa3 handshake. So there is no need for hcxpcapngtool to convert them. An attempt result in "PMK not recoverable."
