I'm trying to crack the WPA2 password, but I get some kind of error.
What am I doing:
I have.pcap dump, I'll convert it to .hccapx:

./cap2hccapx file.pcap output.hccapx

and he writes to me that 2 handshakes are recorded in the file.
next, I'm trying to decrypt the password in hashcat:

hashcat -m 22000 -a 0 output.hccapx rockyou.txt

but I'm getting errors.:
Minimum password length supported by kernel: 8
Maximum password length supported by kernel: 63

Hashfile '/Users/user/Desktop/output.hccapx' on line 1 (HCPX): Separator unmatched

What could be the problem?
