CryptPad: open source technology at the service of privacy

The objective is to present new open source technology using end to end encryption while providing very advanced collaboration features.

Proposal format


As users and organizations we are more and more relying on technology for everything we do, weather it is our personal usage or our business usage.

How much do we need to trust our technology providers to handle our data with care? Is there any way we can be more in control of our data?

The CryptPad project is being build based on a new approach, end-to-end encryption, raising the bar of data security and privacy, while providing a high usability and many collaboration features, including real-time collaboration.

In this talk, I will present the challenges we are tackling with CryptPad, what specific open source technology we have used and developed for CryptPad and how far we have advanced to provide an end-to-end encrypted collaboration suite.
