OnionShare

OnionShare lets you securely and anonymously share files of any size. It works by starting a web server, making it accessible as a Tor onion service, and generating an unguessable URL to access and download the files. It doesn't require setting up a server on the internet somewhere or using a third party file-sharing service. You host the file on your own computer and use a Tor onion service to make it temporarily accessible over the internet. The other user just needs to use Tor Browser to download the file from you.

 

You can download OnionShare for Windows and macOS from https://onionshare.org/. It should be available in your package manager for Linux, and it's included by default in Tails.

 



• Once you have installed OnionShare, open the program from the start menu.
• Use the 'Add Files' and 'Add Folder' buttons or 'Drag and Drop' the files you want to share.
• Click the 'Start Sharing' button.
• This will generate a TOR (.onion) link to the files and folders you are sharing.
• Provide this .onion link to anyone with whom you want to share the files and folders. 

By default OnionShare stops sharing these files and folders after the first download. If you want to share the files and folders with multiple people open the settings menu (gear icon in the lower right of the OnionShare screen) and uncheck the 'Stop sharing after first download button'.

 



 

You must have OnionShare open and running on your computer to share files and folders. Once you quit OnionShare the URL to access your shared files and folders won't exits anymore. If you re-add the same file and folders to a new session of OnionShare, a new URL is generated.

 

These files and folders can only be accessed using TOR (https://www.torproject.org/), so anyone with whom you plan to share files and folders must have TOR installed on his or her computer. That being said, anyone running TOR and knowing the .onion URL to access these files and folders can download them anonymously. As is often the case when using TOR, very large files can take a long time to download.
