Dictionary Attack with increment - Saduj - 08-02-2023
Is there a way to do a dictionary attack with an increment, so, say I know the password is 8 characters. Can the dictionary attack go through and only try the 8 letter words in the dictionary? Thanks in advance.

To be fair, there's not a lot on the wiki to answer this specific question.
Some folks would probably either one-time filter the wordlist on the fly with `grep` or similar, or else grep it once and save the results, depending on the size of the wordlist.
You can also use `-j` with a rules file that contains `_8` ("_" is a "reject" rule, but only works with `-j` / `-k`).

Thank you, I was just looking into grep. I used power shell in windows to Get-Content D:\Wordlist\weakpass_3a | Select-String "^.{8}$" > 8_letter_words.txt and it's currently compiling the list of 8 letters saving to file.
I will def look into the other option you offered. -j. I appreciate your help and leads you have given me. I'm new to hashcat and looking to explore all its capabilities and the like. Thanks again

I've updated the command, as it was choosing 8 characters, but it was also choosing 9 and up characters as well, so the modified command is below, just in case someone else is trying to do something similar you can pass it on.
Get-Content D:\Wordlist\all_in_one_p | Where-Object { $_.Length -eq 8 } > 8_letter_words.txt
(ruining under windows Power Shell will only choose 8 characters, just change D:\Wordlist\all_in_one_p where your wordlist is currently and the words.txt output will be under C:\Users\your pc name here\ )

Ah, I totally forgot - hashcat-utils 'len' utility also supports this, efficiently.
