hcxtools - solution for capturing wlan traffic and conversion to hashcat formats

[ZerBea]

Ok, my fault. Didn't noticed that you mean the potfile.
That depend on your hascat version. The new potfile format is the result of PBKDF2:

Code:

PMK*ESSID(in HEX)*PSK

So you have to recalculate your old values by PBKDF2 and store this result as new potfile. It can be done by simple pearl/python scripts.
Or you can use wlangenpmk/wlangenpmkocl, hcxpmkidtool. That require a little bit bash scripting to convert the results to the final potfile format.
