Hello,
iam new to Hashcat. Because its really hard for me to understand the text based version of hashcat i loaded the Hashcat GUI. Its a bit easier for me but quite challenging.
I configured The Gui version as you can see below to crack a .rar file with a Brute Force Attack. I know that its a 5 character Password on it.

After hitting the "Reverse Engineer" Button to Start the Crack process, the cmd opens up and giving me the following error:
![[Image: JAjx9.png]](https://puu.sh/JAjx9.png)
What am i doing wrong? I dont understand it. Can someone help me out with this? I got an AMD Vega 56 Graphicscard and already installed the required driver version 22.5.1.

I dont know exaactly what you mean. In the Input field i added the file that should be cracked otherwise the program doesnt know that it has to crack the password of this file, right?

Hashcat cracks hashes, not programs. So you need to retrieve the hash of the encrypted file, like slyexe wrote, save that hash to a file and then crack on that.
You need some basics to work with this. I recommend these videos:

Press Win+R type cmd and press Enter
Then example cd c:\john\run
Next command: rar2john.exe yourfile.rar
done! you got rar hash!
Example hash: $rar5$16$74575567518807622265582327032280$15$f8b4064de34ac02ecabfe9abdf93ed6a$8$9843834ed0f7c754

Okay its running. I changed the name of the directory where hashcat is stored. there was a blank in it. i wrote anything together and now it works.
But i think its very slow it does only ~41000 H/s
Why doent it do Millions of H/s?
I have seen that in other cases its much faster like Mh/s or GH/s
I hoped that hashcat would be faster than "Accent RAR Password Recovery". With this Program i will do the same amount of PW per second.
Is it normal that hashcat isnt faster?
