Summary : Collection of Python classes providing access to network packets
Description :

Impacket is a collection of Python classes focused on providing access to
network packets. Impacket allows Python developers to craft and decode network
packets in simple and consistent manner. It is highly effective when used in
conjunction with a packet capture utility or package such as Pcapy. Packets
can be constructed from scratch, as well as parsed from raw data. Furthermore,
the object oriented API makes it simple to work with deep protocol hierarchies.
