Thread: Dedicated hashcat brain server

| 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... |

Thread: Brain as a centralized potfile?
Post: RE: Brain as a centralized potfile?
| 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... |

Thread: Missing example hashes
Post: RE: Missing example hashes
| I'll take a look. Thanks for the heads-up!
Note that you can often use 'hashcat --example-hashes' as a workaround. |

Thread: Missing example hashes

Thread: Wordlist massive attack
Post: RE: Wordlist massive attack
| You can assemble the passphrases from a one-word-per-line wordlist, using princeprocessor, and then pipe it to hashcat, using one of the prince_*.rule rules files to supply more work to the GPUs. |

Thread: Rule Question
Post: RE: Rule Question
| Fair question.
If the rule file contains the "do nothing" rule directive ( : - just a colon by itself), then the original unmodified input words will be used. |

Thread: Should I be using a rule instead?
Post: RE: Should I be using a rule instead?
| There's no way for a single mask to express optional characters (that I'm aware of).
But if you pass a file containing the masks, they are processed in succession very quickly. |
