hashcat Forum

Hi,

I was trying to find many answers to questions I have but the wiki is poor with information and many are outdated. Searching google didn't come up with results I want as well.
I have some questions I hope someone can answer and thanks in advanced.

1- What's the difference between hash mode 22000 and 2500, which on is faster/better?
2- How can I tell hcxdumptool to dump either 22000 or 2500?
3- Is it ok if I do --force for

Code:
Intel's OpenCL runtime (GPU only) is currently broken.

We are waiting for updated OpenCL drivers from Intel.

You can use --force to override, but do not report related errors.

4- I Also updated hashcat today to v6.0.0 and I'm get the following error which I didn't get using v5.1.0:

This breakdown will give you some answers.

1. Your hardware is dates
2. Your using a mobile videocard which is not recommended for hashcracking.
3. Hashcat requires OpenCL 1.2 or higher & CUDA SDK for videocards in hashcat 6.0 which appears yours does not support.

As for your questions.
1. Difference between hashmode 22000 is the newer most reliable method for WPA2 where as 2500 is the old standard hccapx which is no longer used.
2.Download the most recent hcxtools and use hcxpcapngtool to convert your captures to the new format.
3. Using force will only cause more grief for troubleshooting as well as possibly cause faulty functionality of hashcat (not cracking known passwords for example)

In short, your hardware is too old for the newest rendition of hashcat.

Thanks a lot for your reply.
Okay no problem I understand my hardware is outdated, I will be using some cloud services.
Regarding question 1, I know 22000 is a newer method, but what is new about it? Does it help cracking faster? How is it technically different?
Can I use the current PMKID file I have to convert from 16800 to 22000? hcxpcapngtool seems to support only cap files as input.

Code:
hcxpcapngtool <options>

hcxpcapngtool <options> input.pcapng

hcxpcapngtool <options> *.pcapng

hcxpcapngtool <options> *.pcap

hcxpcapngtool <options> *.cap

hcxpcapngtool <options> *.*

Thanks again for your help!

I forgot to ask you, do I need a handshake or PMKID or both for 22000? Thanks.
