### Use of third party tools¶

Once the data has been sniffed it is possible to use third party tools in combination with Ubertooth to obtain critical info. One of the most famous third party tools includes the tool ([crackle]https://lacklustre.net/projects/crackle/).

You can install with the command :

$sudo apt install crackle After the installation process, the following command can be issued to obtain the keys : $ crackle -i capture.pcap -o result.pcap

Other frameworks and tools include : bettercap and gattool.
