Oh my god! I re-read again the entire thread... and sorry undersc0re... you were right!! my mistake. I read your post about hashcat very quickly first time and I thought it was the "normal" error regarding the opencl drivers... but I didn't saw this:

Old hccap format detected! You need to update...
Sorry for that. You are right, hashcat has been updated and now instead of hccap format a new one hccapx is needed. And you MiAl were right too...

First time I saw hashcat 3.0 I fixed the opencl drivers and I updated the line command and the output parsing based on a hashcat version detection (old style for hashcat 2.x and new for 3.0)... but it seems in newer versions this mandatory format change for capture file was introduced.

Now I have a hashcat 3.5 fully working and I can do the needed tests... but the problem is I don't know exactly were this mandatory changed was introduced. I know it wasn't at 3.0 but not sure if maybe was at 3.20 or maybe at 3.30. Does anybody know exactly when was introduced? I need to know that exactly in order to detect version and then do the change or not to make airgeddon compatible with all versions... can anybody help with this? thank you.
