Post: RE: Combinator - how to save combined files.
| I assume that you know that you could just regenerate them when you need them, and save the disk space. :)
But saving general command output to a file is an OS/commandline thing - just basic redire... |

Thread: Variable mask in the middle of the password
Post: RE: Variable mask in the middle of the password

For at least some part of the attack, you can hard-code a prefix and suffix:
Code:

Thread: Parsing a Potfile

| By default, cracks will be written to hashcat.potfile - you don't need -o. If you use -o, hashcat assumes that you're semi-automating something and a lot of the output is suppressed. |

Thread: Solution to use very large wordlist
Post: RE: Solution to use very large wordlist

A) your attack is malformed (can you post your syntax, omitting any real hashes?), or
b) it's a pretty fast hash and y... |

Thread: New Attack-Mode: Association Attack
Post: RE: New Attack-Mode: Association Attack
| "Association" is a general term here that allows attacks to be targets *on a per-hash basis*.
In other words, you don't have to try each word against each hash. Instead, you can try just one word ag... |

Thread: [sha256] Hash inside a hash
