7z 11600 hash file
#1
Hello,


I am trying to crack a 7z archive so I generated a hash file from 7zhashcat64 and got it to processing using the latest hashcat v6.1.1



My first problem is that apparently that hash refuses to run. I used this simple command first to confirm that it works first of all:



hashcat -m 11600 -a 0 --force hash.txt -r rules/best64.rule



Stops after one second. Runing hashcat -11600 -b shows this, basically starts then stops immediately, md5 and other hashes are working:



Code:
hashcat -m 11600 -b

hashcat (v6.1.1) starting in benchmark mode...



Benchmarking uses hand-optimized kernel code by default.

You can use it in your cracking session by setting the -O option.

Note: Using optimized kernel code limits the maximum supported password length.

To disable the optimized kernel code in benchmark mode, use the -w option.

This is the result of hashcat -i. I already clean installed the drivers for the AMD video card (RX 570).

Maybe the GPU can't support it and I need to run it CPU only?

My second problem is that I know part of that password, specifically the beginning, I have tried to follow the instructions here but the commands throw various errors. https://hashcat.net/forum/thread-9362-po...l#pid49458

I simply need to brute force a bunch of numbers after the beginning word. Is there a simpler command to do it?
