Libcrafter is a high level library for C++ designed to facilitate the creation
and decoding of network packets. It is able to craft or decode packets of most
common networks protocols, send them on the wire, capture them and match
requests and replies. It enables the creation of networking tools in a few
lines with a interface very similar to <pkg>net-analyzer/scapy</pkg>. A packet
is described as layers that you stack one upon the other. Fields of each layer
have useful default values that you can overload.
The library is designed to be used in multithreaded programs where you can
combine several tasks simultaneously. For example, you can easily design
something that sniffs, mangles, and sends at the same time you are doing an
ARP-Spoofing attack. It also contains a very naive implementation of the
TCP/IP stack (fragmentation is no handled yet) at user level that enables
working with TCP streams. This facilitates the creation of tools for data
injection on arbitrary connections, IP spoofing and TCP/IP session hijacking.
