reply to : Thanks! Hopefully this isn't going too off topic, but I have one more question for you: how can I increase the speed of how many keys are being tested by aircrack-ng? Would an increase in RAM help? Or does the speed rely on the processor speed?
you can use your graphics card to churn out thousands of more passwords per second using oclhashcat
I have 2x Radeon R9 295 X2 - PCI-E and can churn through 500,000 passwords per second. vs the 2000 per second on just my i7 CPU!
Its pain in the butt to setup, but amazing once done. Mine is broken at the mo since the move to Kali 2016.1 rolling ed (hence why i'm here)
all you need to do is convert your cap file to a hashcat readable one
To Convert :
aircrack-ng -J NewHashCatCapName AircrackCapName.cap
oclHashcat -m 2500 NewHashCatCapName.hccap /path/PasswordList.lst --force --gpu-temp-retain=55 --gpu-temp-abort=79
temp restrictions are there to stop your PC turning into a small fireball!
as i mentioned, im broken in Kali Rolling 2016.1, i cant install the ati graphics card drivers...so oclhashcat cant talk to them properly. there are plenty of out of date guides that dont work...even here :
How to install AMD Catalyst 15.7 (fglrx 15.20.1046) on Kali 2.0 (Sana)?
working on a new guide if i ever fix it myself :-)
