OnionShare lets the user share files securely and anonymously. 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 does not require setting up a separate server or using a
third party file-sharing service. Files are hosted on the machine the
program is run on. The receiving user just needs to open the URL in
Tor Browser to download the file.
