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
Post: RE: Missing example hashes
| OK, I've done the easy ones (that don't require a file upload to hashcat.net), and I've made inquiries about the remainder. Thanks again - good eye! |

Thread: Missing characters from hashcat brute-force?
Post: RE: Missing characters from hashcat brute-force?
| Yes, the default incremental mode is not a full brute force, but rather one that is optimized for likely candidates without being exhaustive:
Guess.Mask.......: ?1?2?2?2?2?2?2?3 [8]

Thread: Mining Rig for hashcat

Thread: Migrating Brain Server Data

If/when it becomes necessary, the migration will vary, based on wh... |

Thread: MD5: Need Advice
Post: RE: MD5: Need Advice
| Yeah, it sounds like you need a mode that I don't think hashcat currently supports:
md5(md5($salt).md5($pass))
You could then format your hashes as [hash]:[username], and use the username as the... |

Thread: md5($salt1,password,$salt2) ?
Post: RE: md5($salt1,password,$salt2) ?
| That should be irrelevant. Only how special characters (like "?") are escaped on the OS-native command line (not a hashcat issue) should vary between the platforms. |

Thread: MD5 Help
Post: RE: MD5 Help
| Do you mean that the plaintext is 32 characters?
If so, then unless you have a strong idea of its composition, bruteforce cannot reach even half of that keyspace. |
