ANP (Agent Network Protocol) is an open-source protocol for agent-to-agent communication featuring a three-layer structure based on W3C DID and web semantics. Version 1.1 has been officially released, highlighting interoperability, DID-integrated messaging, and end-to-end encryption.

agmsg 1.2.0 has been released, introducing remote synchronization capabilities for inter-agent messaging across different machines, with end-to-end encryption and self-hosted sync server options.

Signal introduces automatic key verification, a feature built on key transparency that provides a streamlined way to confirm there is no unexpected party in an end-to-end encrypted session, complementing the existing safety number system.

The article argues that web-based end-to-end encryption is inherently insecure because the server distributing the client code can push malicious updates, making the threat model incoherent. It criticizes services like WhatsApp and Signal for similar flaws.

Columba is an open-source project based on the Reticulum mesh network protocol, allowing messaging and voice calls over Bluetooth, WiFi, LoRa, etc., without requiring internet, base stations, or central servers, with end-to-end encryption.

Moxie Marlinspike's Confer is developing end-to-end encryption for AI chats, with posts on connectors, encrypted memory, private inference, and more.

This article describes a proof-of-concept tool that exploits Slack's video embed feature to achieve end-to-end encrypted messaging within Slack, using browser crypto and openpgpjs.

Former Signal developers and cryptographers from Harvard and Microsoft Research release Encrypted Spaces, a set of open-source libraries enabling developers to build end-to-end encrypted collaborative apps using zero-knowledge proofs.

Secluso is an open-source, end-to-end encrypted home security camera system for Raspberry Pi that allows remote access without cloud surveillance. It features a 5-minute setup and reproducible builds.

XChat, a private end-to-end encrypted messaging app from X (formerly Twitter), is now available for Android pre-registration.

The article announces a major upgrade to the ANP message protocol, designed to facilitate secure, cross-domain collaboration between AI agents. Key improvements include stronger security standards, enhanced end-to-end encryption using Signal-style methods and IETF MLS, and better file transfer support, while explicitly excluding multi-device support to maintain protocol simplicity.

Meta is removing end-to-end encryption from Instagram DMs, effective May 8, 2026, citing low opt-in rates. The decision comes amid controversy, including a New Mexico lawsuit alleging E2E encryption hinders child safety efforts, with the company directing users to WhatsApp where E2E is enabled by default.
