Error when using the hashcat utility .pcap to .hccapx file

[rikstick]

Hi.
Wireshark default format is pcapng. cap2hccapx doesn't support pcapng.

Thanks ZerBea,
When I save the captures, I'm changing it to Wireshark/tcpdump in the file type dialogue box. In other words, I'm not leaving it in the default .pcapng format.

Any ideas what's wrong?

Thanks,
