NAME

       onionshare  -  a  tool  for anonymously sharing files over a temporarily set up Tor Hidden
       service.

SYNOPSIS

       onionshare-gui

DESCRIPTION

       OnionShare lets you anonymously share files. You host the file on your  own  computer  and
       use  a  Tor hidden service to make it temporarily accessible over the Internet. OnionShare
       sets up this hidden service up for you. It then generates an unguessable URL to access and
       download the file.

       Before  you  can  share  a file, you need to open Tor Browser in the background. This will
       provide the Tor service that OnionShare uses to start the hidden service. All  Tor  hidden
       services  (any  website that's accessed through a .onion domain) are automatically end-to-
       end encrypted.

       In the case of OnionShare, the crypto key lives in /tmp/onionshare/tmpXXX/private_key. The
       .onion  URL address itself is a fingerprint of the key, which lets the Tor network look up
       the public key and start an encrypted session. So as long as you transmit  the  OnionShare
       URL  successfully,  the recipient who loads it in Tor Browser gets an end-to-end encrypted
       session with the server.

       When you open OnionShare you will be prompted to select a file to share.  The  unguessable
       URL is then generated and automatically copied to the clipboard.

       The  person  you want to share the file with just needs to use the Tor Browser to download
       the file from you, using the URL you  sent  to  them  over  another,  possibly  encrypted,
       channel like encrypted e-mail or a chat using OTR.

       It takes around 30 seconds until the hidden service is available over the Tor network.

       OnionShare's  default  behaviour  is  to shut down the hidden service and to close the GUI
       once the file has been downloaded. You can prevent this behaviour by deselecting the "Stop
       server automatically" option. This can be useful if you want multiple people to access the
       same file.
