A simple Meteor + Sandstorm app for sharing client-side encrypted files. Requires a browser with a working implementation of the AES-GCM webcrypto API. Stable releases of Chrome/Firefox should work, though note that Chrome restricts WebCrypto access to secure origins.
Do not use this for anything that requires better-than-plaintext securty, given that the code is pretty much untested and unreviewed.
Here is a demo instance. If you want a bunny, the password is iloveoctocats.
To run locally without Sandstorm:
$ curl https://install.meteor.com/ | sh
$ meteor run
To run with Sandstorm, follow the instructions at https://github.com/sandstorm-io/meteor-spk to download Sandstorm and meteor-spk. Run meteor-spk build path/to/package.spk to build the Sandstorm package. Then load the package into a Sandstorm instance after logging in - you can either set up a local instance or just use https://alpha.sandstorm.io.
Caveat: Local instances that are running without HTTPS at an aliased URL like local.sandstorm.io will not work in Chrome since WebCrypto access is considered a sensitive feature.
