Hi there! I am trying to figuring out how to use hashcat like this.
Let's say we are using bruteforce mode.
candidate: adsdfji
I want to double it and separate by an underscore(or any special character): adsdfji_adsdfji
or adsdfji@adsdfji
Is there are a way to achieve this? So they are basically one password but in a different format with added redundancy.
It would save a lot of time because it basically reduces the candidates to half.

You can pipe hashcat into itself, so the following is an option:
hashcat -a3 mask | hashcat -a0 hash -r rulefile
The rule file could contain rules that will fx append a special character at the end of a candidate, duplicate the entire candidate incl. the appended character and then remove the appended character at the end, which would create the candidates want. Example:
$_ d ]
$@ d ]

Hey there! Thanks for the answer! So it is possible. Never used rulefiles so I need to learn it. Also piping hashcat into hashcat is kinda genious
I will try this method.

It works thank you very much!
