Help making custom charset/rule

[ZerXes]

another user have created a python script that generates cleartext-keys that fill the requirements that I can pass through to hashcat.
However the pythonscript itself is being a bottleneck and I end up running about 60 000 WPA hashes/s.

Why not using maskprocessor? http://hashcat.net/wiki/maskprocessor

Yeah, If its possible to create rules for the maskprocessor that fulfil my criteria that would be awesome, is that possible?

I think this whole thread is an extension of the “Pseudo Markov” request I made earlier.

This is absolutly not about markov. Its about a bug in the default password generation for these routers. The exploit code is in stkeygen.

I was referring to this…

So I need help making a charset and/or rule that makes hashcat only look for PSKs filling the fallowing criteria:

I understood it to mean that ZerXes was asking for a way to make a specific pattern or password values using hashcat. To make a list as he wished wouldn’t it require a type of “Pseudo Markov” feature ? I understand he could simply brute force, but as he knows a lot about the password layout he could fine tune his brute force and reduce cracking time.

I am not aware of a way to manipulate the standard rules feature to meet all the requirements he mentioned. I can work out the first 2 but not the rest as I believe this would require the “Pseudo Markov” feature I mentioned above.

Is 10 chars total
Is only the hexadecimal chars, 1 to F (Uppercase)
Contains at least 1 digit
Contains at least 1 letter
Same letter or digit may only exist twice in same key
At least one letter or digit exist twice in same key

You are clearly much better at using rules than I am atom so would you please explain how ZerXes could achieve this pattern without the “Pseudo Markov” feature ? I would dearly love to be able to do it myself and I would be very grateful to learn how to do it using the current tools as I have been unsuccessful so far.

Thank you.

Yes, that is exactly what I want to achieve
