Encrypted Spaces: Bringing Signal-Style Privacy to Collaboration Apps
A team behind the Signal protocol is building Encrypted Spaces, open-source infrastructure to bring end-to-end encrypted, verifiable storage to collaboration apps like Slack, Google Docs, and Discord. Described in a Research Preview with a Spaces demo, the project uses zero-knowledge proofs to keep data encrypted on central servers while allowing cryptographically verifiable collaboration. It aims to be a reusable platform for developers rather than a consumer product, potentially fueling encryption-policy debates, with existing options from Proton, CryptPad, and Fileverse offering E2EE tools.
