    libsignal

    libsignal

    Home to the Signal Protocol and other cryptographic primitives

    ...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. Although its primary use is within the Signal ecosystem, its documentation and exposed interfaces allow developers to explore modern secure messaging primitives or use pieces of the protocol in experimental applications.

    Quiet

    Quiet

    A private, p2p alternative to Slack and Discord built on Tor & IPFS

    Quiet is an alternative to team chat apps like Slack, Discord, and Element that does not require trusting a central server or running one's own. In Quiet, all data syncs directly between a team's devices over Tor with no server required. Quiet is not audited and should not be used when privacy and security are critical. It lacks basic features and probably won't replace your Slack or Discord yet. That said, it works surprisingly well and we use it daily as a Slack replacement. Quiet is for fans of software freedom, decentralization and privacy tech, and for anyone craving a future where humanity can collaborate effectively online without trusting our communities, networks, and data to giant corporations. ...
