Onionshare lets you use the Tor network to send files of any size securely, without having to upload them to a service like Dropbox or allow a third party to access your private cloud.
Η Onionshare works by creating a temporary ".onion" web address on the Tor network that you can share with a friend. When you're done, you can stop sharing, and the address will no longer work. Of course, if you are interested in security, be sure to encrypt the message with the .onion address you send to your friend.
The service requires you to install the corresponding application on your computer. This installation is very simple. Those of you who have Windows can download this installer from github and all you need to do is run it. Respectively there is an instaler for them as well Mac OS X users. Finally there are instructions for Linux Debian, Ubuntu, and Fedora users. If you are not running any of the above linux distributions, the application is open code, so you can always build it yourself following the relevant instructions.
The Onionshare is a simple graphical program and has a basic interface. When you open it you will be taken to the main window which has an area where you can move your files you want to share as well as a button you can click to add them. Once you have collected everything you want to share, click the "Start Sharing" button.
It will take Onionshare a few seconds to generate a url. When everything is ready, a URL will appear so you can send it to your friends. When you have finished sharing, simply click the "Stop Sharing" button and the ".onion" link will no longer be available.
Once you have the URL of an Onionshare archivey, you can browse this address using the Tor browser. The page you will see is quite simple, and besides a download link for your file, it has various information.
