Extract the keyboard input from wireshark datapack
As we all know that wireshark can capture the keyboard input and store it in pcapng file. You can find them in every usb.capdata attribute.
This script can help you extract the keyboard input and restore them into the key.
If you need more options when using tshark, I recommend that you use the python script instead of using the binary executable program.
CAUTION: The result that restored by this script sometimes may not be the $flag, it may also encrypted by other way.
