Can I enter code into aircrack rather than a dictionary?

[charliegirl]

The primary dsl provider in my area bundles wifi routers with wpa already implemented, using randomly generated hex passphrases. But the passphrases are always the same length (i think it was 6 digit, but possibly 8 digit).

I know this could amount to 4 billion passphrases, so weeks of brute force, but i figured there might be a way to streamline the aircrack algorithm given that instead of the whole asci alphabet, it only has to try hex values in a predictable order.

But i can't even figure out how to have aircrack use a line of code instead of a dictionary, and i dont yet know what that code would entail. Does this sound like an impossible plan, or is it workable? If so, how?

aircrack-ng / documentation will get you started on this.
This is not a BT issue.

What you can try doing is using airolib-ng and create tables with the predefined characters and ESSID and then feed aircrack with these tables side stepping any coding.
