The NetShare programs are designed to implement a computer network (the NetShare network) scheme with the purpose of file exchange. Although NetShare has some concepts in common with Napster and Gnutella, there are important differences. Clients that connect to the NetShare network are authenticated by the server and are accepted only if they produce proper credentials. Data exchange in a NetShare network is also encrypted to prevent snoopers from gaining access to private files. NetShare server is the program that manages a NetShare network. This program is responsible for creating random private/public keys for use by the clients, authenticating the clients that access the network, keep access logs and generally manage the network.
