For example, if a website login that uses password of a specific format containing 3 letters and 3 numbers like abc123, qwr345, yta921...

What tools on Kali Linux can crack this type of password and what would the command be?

  • FYI real world websites rarely have password format constraints that fit a pattern exactly like that; those are probably more often found in a CTF game. Although I've seen some pretty terrible password policies, so I know it's not impossible. – John Deters Feb 9 '18 at 5:31

You probably want to use crunch. It can be configured to produce permutations that meet the rules you've mentioned.

  • Thanks did some research and found it was crunch 6 6 -t @@@%%% – Martin Gwynn Feb 8 '18 at 3:40
