With Retroshare you can establish encrypted connections between you, your friends and family. You create a network of computers which provide various distributed services on top of it: forums, channels, chat, mail, file sharing… Retroshare is fully decentralized, and designed to provide maximum security and anonymity to its users beyond direct friends. Retroshare is entirely free and open-source software. It is available on Android, Linux, MacOS and Windows. There are no hidden costs, no ads and no terms of service.
RetroShare can be ran behind a Tor Hidden Service or I2P for incoming connections. The outgoing connections are then sent through a local Tor-Socks-Proxy makeing it possible to obfuscate your metadata which could disclose your Network Friend Graph. The hidden service address (e.g. ld676kr3zr592h3p.onion) is replacing the IPv4 address (e.g. 192.168.1.216) as the listening address for incoming connections. You could also just use a VPN to replace your real IP
Share files with your friends or with the whole network. Use the search to find files. Retroshare uses swarming similar to BitTorrent, to accelerate the download. This makes it possible to share big files with 1GB or more. Your privacy is protected with anonymous tunnels. Only your direct friends might learn which files you download. You can set who has access to your files. This could include your friends, your groups or anonymous users (anyone) on the RetroShare network who you have added to your contact list.
