hashcat Forum

I run this command:

Code:
cudaHashcat64.exe --outfile=result.txt --outfile-format=1 -m 10500 -a 3 outpdf.txt ?u?u?u?s?u

and I get this output:

Code:

and the results.txt file is empty. Why?

The answer is: this happens because you already did crack this specific hash and it was already in your .pot file (see the warning "INFO: removed 1 hash found in pot file"), hence oclHashcat does not try to crack the same and identical hash again and again and again...

You can use:
cudaHashcat64.exe -m 10500 --show outpdf.txt

to get the "results"

or use --potfile-disable to force oclHashcat to crack it again and again and again...

The details about --show, --potfile-disable etc were discussed several times on the forum and can also be lookup up under --help and in the wiki
