hashcat Forum

The file does not exist.

Just use a forum search for simple problems like this.

"Hash" means that it's a literal hash, while "Hash File" means that it's trying to load a file.

If the file is not found on your file system, hashcat fails over to the feature where you can specify hashes directly on the command line. If that hash doesn't parse correctly, it will show this error.

I know (and we are aware) it seems to be not very clear error message, but if you read carefully it says that the command parameter is not a valid hash ("Hash 'Guess.txt'").

Just make sure that the hash file exists. Make sure that the full path is correct and the file name is correct too, including the file extension. Windows sometimes hides the file extension of common files (like .txt)... therefore Gues..txt is different from Guess.hash etc etc

The full path + file extension must be correct.

Hashcat didn't find the file, because it's not there even if you think so... just do a "ls" (linux) or "dir" (windows) and see how the full file names is.

I checked with ls and it seems to be there, any other way of checking?

I just tried cracking example0.hash with example0.cmd and it worked great!

That just means that I have to solve this one problem before I'm on my way!

YES I GOT IT TO WORK, by adding shell script file and removing increment:

Using pure kernels enables cracking longer passwords but for the price of drastically reduced performance.
If you want to switch to optimized backend kernels, append -O to your commandline.

Host memory required for this attack: 2329 MB

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.

Why couldn't I crack it?

Why isn't the space in custom character 4 not showing?

If the hash was:
b64362efb613c96e5e4d47ee7bd67cb6977622d1bf39b5cc48c5c196d18486a6

And the answer was:

Why couldn't I crack it?

don't post hashes: https://hashcat.net/forum/announcement-2.html

it doesn't matter if it's just an example.

New problem:

Integer overflow detected in keyspace of mask: ?1?2?3?4?4?4?4?4?4?4?4?4?4?4?4?4?4?4?4?4?4?4?4

Why would it only show up now?

Is there a way around INTEGER OVERFLOW? I don't care how long it would take to get to the answer.
