A magic-wormhole client in Haskell

hwormhole is a haskell version of Brian Warner's magic-wormhole file transfer program (also called wormhole) that uses the SPAKE2 based wormhole protocol. Magic-wormhole allows the user to securely transfer a file from one computer to another, anywhere in the world. This program interoperates with the Python implementation of magic-wormhole program. We support transferring short text messages, files and directories. If the user has tor or Tor Browser installed, then magic-wormhole can be instructed to use the tor connection in order to protect the IP/Port addresses of the users.

Building

On Unix

You will need cabal-install version 2.2 or above that supports the new-* commands.

git clone https://github.com/LeastAuthority/wormhole-client

and

cd wormhole-client
cabal new-build hwormhole
cabal new-test hwormhole
cabal new-run hwormhole:hwormhole-exe -- send --text foobar
cabal new-run hwormhole:hwormhole-exe -- send /path/to/foobar.txt
cabal new-run hwormhole:hwormhole-exe -- receive

There is a --help command. It works for subcommands as well.

On Windows

1. Download libsodium [pre-built library].
2. Install Visual Studio 2015 redistributable to install vcruntime140.dll needed by libsodium.dll.
3. On a command line shell (assuming ghc and cabal-install are installed and are already in the PATH), set LIBRARY_PATH=C:\path\to\dir\containing\libsodium.dll\
4. Now, follow the steps above for Unix.

Development

Contributions

We welcome all kinds of contributions (bug fixes, new features, documentation, tests etc). Please send them as github pull requests.

What's next?

Support "dilated wormholes" when it becomes available in the upstream.

Feedback

This is my dig at creating a "production" haskell application. I welcome all kinds of feedback. My email ID can be found in the hwormhole.cabal file in the maintainer field or from my github page. I also hang out on the IRC at #magic-wormhole on freenode with handle rkrishnan.

Thanks

We wish to thank NLnet Foundation for a grant that enabled us to work on this project.
