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