Usage

Graphcat just need a potfile with -potfile (default is hashcat, but you can use -john to submit a john potfile) and a hashfile with -hashfile. The hashfile should be in a specific format from the 3 availables formats with -format flag. Default is Secretsdump.

The tool will generate a report with multiple password cracking charts. You can get charts in png with the -export-charts flag.

If a hash occurs more than once in the hash file, it will be counted that many times.

Moreover, if you submit secretsdump with password history (-history in secretsdump command), it will analyze similarity in password history
