Thread: Multiple masks - repeated sequences
Post: RE: Multiple masks - repeated sequences
Do the math of how many combinations it will actually save you, compared to the total number of combinations.
It's rarely worth the effort to eliminate the relatively small number of duplicates lik... |

Thread: Brute-Force mask
Post: RE: Brute-Force mask
There are probably too many combinations to reasonably exhaust, but to model how many masks would be needed, you can use the `policygen` tool from the PACK toolkit:

Thread: CrunchCat (Crunch + HashCat)

Crunch is unnecessary for most attacks:
* Limiting duplicate characters is not worth the sacrifice in speed
* Resumption of candidate generation is built in natively to hashcat

Thread: CrunchCat (Crunch + HashCat)

If your target password is likely less than the max supported by an optimized kernel, adding "-O" to your command line will be significantly faster. This max value varies from hashtype to hashtype - c... |

Thread: On-the-fly loading of gz wordlists
Post: RE: On-the-fly loading of gz wordlists
I'm not sure, but I think that decompressed data can be used "on the fly" - as soon as it's decompressed, without having to wait for the entire file to decompress. |

Thread: On-the-fly loading of gz wordlists

Yes, that seems right. It would have to decompress the whole thing first, enough to analyze the statistics and then cache them. so I assume there would be some duplicated work, just like dictionary ca... |

Thread: Make a word list with hashcat
Post: RE: Make a word list with hashcat
To clarify, do you mean that each word is 62 characters long, and only consisting of the letters '1', '3', 'e', and 'f' ?
If so, this wordlist would be infeasible to exhaust.

Yes, the default incremental mode is not a full brute force, but rather one that is optimized for likely candidates without being exhaustive:

Thread: How long to decrypt SHA256

There's no online calculator that I'm aware of.
Just do the math:
1. Calculate how many possibilities your mask will generate. For example, ?a has 95 possibilities, so ?a?a?a?a is 95^4 or 81450... |
