By default, hashcat expects bare hashes (without username). To ignore username, use --username. With -a 0, you also need to supply a wordlist. If you want to try the default mask attack set instea...

If it's a test hash that you created yourself and has a known plaintext, then it's OK to post the whole hash (as long as you also include the plaintext).

The question of how to create a specific Markov of digits in inverse order is a tricky one that is not easy to do with hashcat itself. Naively, I tried this, but it obviously didn't work: Code: --...

Post: RE: Brain behavior

The target hashlist does have to be file-checksum-level identical, IIRC. But I'm not positive. But it also shouldn't be very hard to create a very simple test case to verify it directly.

Hashcat won't do this today. You might be able to simulate it with John the Ripper's "single" mode, by creating an artificial shadow file, with the expected password in the username field.

The instructions on the wiki page are very clear - create a .reg file with the specified contents, then run it as Administrator and reboot. That last part is Google-able.

1. Yes. All candidates are centrally reported and indexed. For slow hashes, this is effective, because it allows all clients to skip those candidates. For fast hashes, this will quickly bottleneck the...

Progress in this context is 'how many hashes were successfully cracked'. So if you're only cracking a single hash, progress will always be either 0 or 100. :)
