endra 0.3.0

A fully distributed, no-servers, peer-to-peer encrypted messaging protocol.

A peer-to-peer encrypted messaging protocol supporting multiple devices per user.

See the EndraApp project for a GUI messaging application for desktop and mobile implementing Endra.

Features

• fully peer to peer, no servers of any kind
• can function independently of internet connectivity
• full end-to-end encryption ephemeral keys, algorithm-agnostic & future-proof
• multiple devices per profile (user account)
• multiple profiles per device
• can be used as a library for embedding into other applications
• will become part of an expandable ecosystem incl. calendar and file-sharing
• app for desktop and mobile (builds for Linux (Ubuntu 24 x86-64 & arm64), Android (arm64), Windows 11 (x86-64) and MacOS (x86-64 & arm64))

Documentation

The thorough documentation for this project and the technologies it's based on live in a dedicated repository:

• Endra: learn how Endra works
• Walytis Technologies: learn about the suite of tools which Endra is part of, built to enable developers to easily develop peer-to-peer distributed applications.

Project Status EXPERIMENTAL

This library is very early in its development.

The API of this library IS LIKELY TO CHANGE in the near future!

RoadMap

See the Walytis Technologies RoadMap for the current plans for Endra in the context of the larger Walytis Technologies Project.
