bitmessage is a p2p communications protocol used to send encrypted messages to another person or to many subscribers. it is decentralized and trustless, meaning that you neednot inherently trust any entities like root certificate authorities. it uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "noncontent" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs. if bitmessage is completely new to you, you may wish to start by reading the whitepaper.
