Hello all
I’m trying to use hashcat to crack Kerberos pr-auth etype 18, I tried this
hashcat -19900 ‘$krb5pa$18$yara24$KTG.LOCAL$9e369416abca8ad80c4055e1286e0710de928f9b2ce0b3b88e59a17cfe7d9f5103a129dd750d130db33d99b20f37d4bc21d88518c950e7d3’ rockyou.txt
But no results have been found, I wonder why? Am I made mistake or the Kerberos has solved the cracking issue

that was my bet
Code:
OpenCL.Version.: OpenCL C 1.2 pocl
1.2 is old, to old, this is the problem, deinstall pocl and install intel opencl for cpu directly taken from intels website or from your packetmanager until hashcat -I shows at least opencl 2.0

Did you run the command as stated? -19900 should be written as -m 19900. Or is the issue just that it didn't crack? In that case, try other wordlists and rules.

what commands should I write to update to the version 2.0 ?
I have no idea how to do it , and I’m working on [The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali)-linux]

use plain ubunut or
sudo apt update
sudo apt remove pocl-opencl-icd
sudo apt autoclean
sudo apt autoremove
sudo apt install intel-opencl-icd
if this doesnt work, register and download ( i had the directlink, but didnt find it right now)
