Xplico
Xplico is a network forensics analysis tool (NFAT), which is a software that reconstructs the contents of acquisitions performed with a packet sniffer (e.g. Wireshark, tcpdump, Netsniff-ng).
Unlike the protocol analyzer, whose main characteristic is not the reconstruction of the data carried by the protocols, Xplico was born expressly with the aim to reconstruct the protocol's application data and it is able to recognize the protocols with a technique named Port Independent Protocol Identification (PIPI).
The name "xplico" refers to the latin verb explico and its significance.
Xplico is free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 2.
