libsignal is the foundational cryptographic library that implements the Signal Protocol and other essential primitives used across the official Signal clients and servers, enabling secure end-to-end encrypted communication. Written primarily in Rust with bindings and APIs surfaced for Java, Swift, and TypeScript, this library encapsulates critical algorithms like the Double Ratchet, prekey mechanisms, secure key storage, and zero-knowledge group primitives, along with additional utilities for media handling and device key transfer. libsignal abstracts complex cryptographic constructions into reusable components that client applications can adopt to ensure forward secrecy, authentication, and integrity without re-implementing core security logic. ...

...Many communication platforms are vulnerable to MITM attacks by servers or network providers. To prevent it SimpleX apps pass one-time keys out-of-band when you share an address as a link or a QR code. Double-ratchet protocol. OTR messaging with perfect forward secrecy and break-in recovery. NaCL cryptobox in each queue to prevent traffic correlation between message queues if TLS is compromised.

...It is built around OpenClaw and is designed to make agent access available directly inside the chat apps people already use. The project emphasizes a simple graphical setup, double-click installation, built-in skills, multi-model support, and bring-your-own-key configuration. Once connected, the agent can stay available through instant messaging channels, including from a user’s phone. nexu is local-first, meaning its design keeps data on the user’s machine rather than routing business information through a hosted service. ...
