Easy & fast with WPACLEAN

If you have a large WPA dump file you need to remove the excess data. You can do this with WPACLEAN utility from the aircrack-ng suite.


Source and/or binaries are available at Aircrack-ng.


$ ./wpaclean  small_capture.cap  big_capture_file.cap

big_capture_file.cap is the file you want to reduce, small_capture.cap is the result file.
Once done you can upload the file 'small_capture.cap' which is smaller.

I'm lazy, do it for me !

You can send us your capture file by email :, we'll do it for you.
