If security is your concern, you should consider this application when connected to your friends and family online. Retroshare, a GUI application that allows us to chat, share files to friends securely. When you feel your current file sharing service you are using is not secure enough, then swith to Retroshare.
Retroshare can be used to chat, mail, file sharing, forum with extra security features for those features. It uses the idea of Peer 2 Peer technologies and better encryption system.
Download and Install
For Ubuntu users, you can install Retroshare with the following command
sudo add-apt-repository ppa:retroshare/stable
sudo apt-get update
sudo apt-get install retroshare06
After install Retroshare icon will appear on your application list (Dash).
On the first use, you will need to create a new profile for you and your computer. You will need to enter your name and create a strong password for your profile. Retroshare will create randomness for better security. This randomness is gained from your mouse movements.
Retroshare is a user friendly chat and file sharing application. It has extra security features that make our chat session and file sharing activity more secure than other public chat services. I recommend this Retroshare for all Ubuntu users. For more information about other platform, wiki and source code, please visit: http://retroshare.sourceforge.net/wiki/index.php/Main_Page
