[HELP] Hashcat Mask - Rams3s - 02-13-2018
Hello,
So i need some help for create a mask.
Here is what i know about the password:
1: It's a 8 chars uppercase password
2: the password never have two same caractere next to the other like AABCDEFG
3: The password don't have more than two time the same letter in the whole password ABCABCA can not work because there are 3 time the A letter in the whole password but ABCABCD work.
4: the same sequence is never repeted in the password: ABHGJAB is not possible AB is repeted.
I don't know if the mask will really decrease the cracking time but i have 50.000 H/s cracking speed so if you can calculate it too it would be very nice.
Thank you very much !

for points 1 to 3 you could use maskprocessor. It supports the -q and -r command line arguments that filter out exactly the password candidates that do not match the policy that you described above.
For #4 you probably would need to create a custom script, because I do not think this is supported by those tools (this feature would probably need to be very flexible and would need to allow substrings of custom length, not only length 2 substrings).
For #1-#3 you could just pipe maskprocessor to hashcat.

Hi,
Thank you for your answer.
How to make the script you talk about?
And finaly, it worth the time to make this script and i whant to know if the cracking time will be really decreased or not. Thank you !
Ps: i use hashcat on windows for the moment, i breaked an The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) installation when i tried to install cuda driver. the command line you gave is correct for windows?
Thank you again and have a nice day !

Ok i got it working on windows but hashcat say password lenght maximum 63 ! but my password is exactly 8 chars uppercase.
RE: [HELP] Hashcat Mask - philsmd - 02-13-2018
That is just a hint how long WPA/WPA2 hashes could be in general (maximum allowed password length for WPA/WPA2).
For some hash types there are even 2 different kernel files (optimized vs pure). For some hash types you could use -O , which is not possible (because it doesn't improve speed) for WPA/WPA2.
The command line parameter that you could add to improve speed is either -w 3 (less lagging) or -w 4 (could lag a lot).
