how to write BruteForce character set!!

[pdo]

that would be simple options

--increment --increment-min=8 and as mask ?a?a?a?a?a?a?a?a?a?a?a?a

but i think you will run into a buffer overflow

Think of it like I wanna bruteforce every possible password ever like the classic airmon-ng with crunch method, that generates and checks passwords on the way without making a dictionary.

What have you tried?
