Hello folks, I'm glad to announce that Pablo Ojanguren and me have been progressing a lot in the GSOC project of adding end-to-end encryption to Wave documents. We have implemented symmetric encryption for deltas that are "on-the-fly", using HTML5 WebCrypto API (via JSInterop). Our next step is going to be able to decrypt deltas that are "on rest" (from a document snapshot). You can read more details on this [blog post](https://llopv.github.io/gsoc-2017/e2ee/2017/06/30/encrypt-ot-1.html). Our code can be found at [github](https://github.com/llopv/incubator-wave/tree/gsoc-2017), although Pablo is still peer-reviewing it. We will make a merge request when we find it ready. I hope you receive these good news with joy. And please, feel free to do any suggestion or ask any question. Best, David Llop.
