RetroShare is a decentralized, private, secure, cross-platform, communication toolkit. RetroShare provides file sharing, chat, messages, forums, channels and more.
Secure chat RSS
The next generation of peer to peer file sharing. Unlike classic P2P softwares, RetroShare only connects to trusted friends and not just anyone, this is called a "friend-to-friend (F2F)" network.
RetroShare is free software for encrypted filesharing, serverless email, instant messaging, chatrooms, and BBS, based on a friend-to-friend network built on GPG (GNU Privacy Guard).
