Post: RE: --restore with the change of workload profile?

To clarify: adding command-line options to a restore process generally doesn't work very well. You have to modify the restore file manually. I recommend making a backup copy of it first. The script th...

Interesting idea. I haven't worked with readpst before, but if the results are plain text, then the remaining question is how to turn emails into wordlists. Splitting the resulting text files into com...

Your GPU is getting too hot. Improve your cooling / airflow / thermals.

Post: RE: hashcat 3.60 / hashcat 4.x many hashes

I'm not clear from your post which tests are the ones that are for a large number of hashes. And to clarify, by "Optimized" do you mean that you are using the -O flag?

I've never actually tried running hashcat from a live USB - interesting. hashcat is dependent on I/O for some kinds of attacks, but not others. If it is a fast hash and a straight dictionary, you c...

K a l i is known to not be very Open-CL friendly. But generally, if OpenCL can see your devices, hashcat should work.

I personally prefer something like Ubuntu (desktop or server), but I don't think there's a difference in compute power.

I haven't worked with this hash type before, but A) it's not pure bcrypt, and B) the portion after the colon is, I'm told, not a salt.

As the number of remaining hashes drops, performance per hash should increase. In other words, once only one hash remains, performance should be the same as if the target was only a single hash in ...

Huh - fair point! My understanding of how --restore works is that it's mostly a record of what command-line options were used, for the purpose of reinvoking hashcat. So I think that its application...

You can use whatever rules make sense for your target. You may have to experiment with --stdout to determine whether the combination of --case-permute and your rules are doing what you're expecting.
