onionfile

Simple file sharing over tor hidden services (v3).

No need to pre-install tor, everything is packaged in.

Use via npx (built-in with npm 5.2.0+):

$ npx onionfile ~/shareme.txt

http://guy9ocyi3hac5j7kh3ua336qr4t5k6q35ncyxbsrajp3smc4yp7gxtyd.onion

That's it! Share the URL with the recipient to give her access to ~/shareme.txt.

If a path to a directory is provided, the entire directory will be made accessible with a directory index listing all the available files.

Note: it might take a few moments for the hidden service to become available.

Instead of using npx, you may install the package locally to make it available simply as onionfile:

$ npm install -g onionfile

$ onionfile ~/shareme.txt

Share files easily and privately.
Doesn't require accepting incoming connections, no port forwarding needed.
Self-authenticating URLs, in both directions: the URL is required in order to access the file (serving as an access key), and it authenticates the identify of the server (protecting against MITM attacks).

To Dead Canaries's awesome granax and hsv3 libraries, which made writing this utility a breeze (<30 LoC)!
