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.

"WhatsApp and Messenger to Implement Interoperability with Signal Protocol for Enhanced User Safety"

In compliance with the Digital Markets Act, Meta plans to make WhatsApp and Messenger interoperable with third-party messaging services, requiring third parties to use the Signal protocol for encryption. While touting the benefits of the Signal protocol, Meta also emphasizes the need for third parties to demonstrate similar security guarantees. The company outlines technical details of how encryption will work and states that third parties will be responsible for hosting media files. However, Meta hedges on the security of third-party providers, suggesting potential security concerns. Third-party providers will need to sign agreements with Meta or WhatsApp before enabling interoperability.
