GPU Some Functions Are Not Supported The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) Linux - hash - 08-20-2021
Hi, I am new to The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) and i tried to use hashcat. So, first, it didn't show my GPU and i installed the latest drivers using apt-get install. I also downloaded compatible CUDA for GT740. And, now, it identifies my GPU but it has some errors.
Here is the log:
"
hashcat -m 2500 -d 1 -a 3 3401_1629484414.hc22000 ?l?u?d?s ?1?1?1?1?1?1?1?1?1?1?1?1?1

my problem is with 'nvmlDeviceGet...' Not Supported thing. I saw a thread here that basically said i should re-install NVIDIA drivers and CUDA but i don't know how to (as in, i don't know how to completely purge the drivers so it will be a clean installation process) nor do i know what should i install *after* i uninstall the current drivers. Like, it should already be the latest.
In short, i am in need of a little bit help here. Thx.
Note: it doesn't matter if i introduce a legit file to the hashcat so "3401_1629484414.hc22000: No such file or directory" is not relevant to the issue here.
Edit: Ah, also, why hashcat converted my cap file to hc22000?

Hash mode 2500/2501 and hash mode 16800/16801 is deprecated and the online converter doesn't convert to this hash files any longer. Please read more about the new hash mode 22000/22001 and how to use it, here:

Your command line is wrong. Please read more about mask attacks, here:
https://hashcat.net/wiki/doku.php?id=mask_attack
Your mask is huge and the key space will be to big to handle running your GPU.
Your hashcat version is outdated (latest 6.2.3)
Your GPU (not K A L I) is old and doesn't support some features.
K A L I is not the best choice to be used in combination with hashcat.
You may have noticed that the robot changed the name to "The-Distribution-Which-Does-Not-Handle-OpenCL-Well"
It is one of the most recommended Linux distro for ethical hackers but it is definitely not recommended for Linux beginners.
