Hashcat + LUKS + RTX 2080 (laptop) - hellrezistor - 11-14-2019

Hello Guys!

I am trying recover a password from a partition using this comman:

Code:
hashcat64.exe -m 14600 -a 3 -D 2 --session=mysession -w 4 C:\Users\User\kingston.001 C:\Users\User\hashcat-5.1.0\masks\rockyou-1-60.hcmask

Someone have this issue?

[*] 
Code:
nvmlDeviceGetFanSpeed(): Not Supported


The HashRate Its 600~500 Hash/s . Its the right?


Full In/OutPut:

I have compared with this log from other user benchmark, and him have better values:

Thank You all!

maybe you use a notebook or a GPU without fan ?

luks/cryptosetup etc use a cost factor (think of iterations), it depends on how powerful the CPU on the system the disk was first encrypted (or password changed) is. This makes sense because the user shouldn't wait too long to log in in general but it should also be quite difficult to crack (so it depends on the system CPU power). You can't compare apples to oranges if anything you would need to compare to your --benchmark values (and even those in theory could change over time and with different hashcat versions etc)

Hi philsm,

My CPU it's i7-9750H 2.6Ghz , 16GB RAM

You are Right, I am using a Laptop (but have fan, maybe not same type of fan)

The partition has been encrypted into a VM machine (lower resources)

Thank you for that attention about GPU vs CPU and LUKS!
