RetroShare is an application to exchange messages and files safely and connect with your friends.
RetroShare is a distribution network that uses p2p technology to create a private network through which you can exchange files, send and receive emails, chat, and participate in various forums and channels.
RetroShare GnuPG also requires the installation of GnuPG, an application that encrypts and signs your data and communications in general. In this way, RetroShare ensures that every exchange you make through it, is done safely while protecting your privacy. Both GnuPG and RetroShare are free, open source programs.
Once the program is downloaded and installed, the RetroShare interface asks you to create a username, complete your profile and enter the password you selected seconds before to connect to the RetroShare network.
You'll see that the RetroShare interface is very descriptive and easy to understand, just like its toolbar and the other services offered by the program, as it is similar to other environments we are familiar with.
When you have logged into RetroShare you can find friends or send them an invitation and start chatting, as well as performing multiple uploads and downloads simultaneously.
