Signal is the opposite — strong encryption, not a workspace you host. Chaos is the overlap: a messenger you run, whose server is not in the plaintext path, and whose delivery path is designed for the broker to die. It uses an original X3DH-inspired handshake and Double Ratchet-style protocol on WebCrypto. It is not Signal, not a Signal Protocol clone, and has not been independently audited. Treat it as a serious engineering product, not as a finished high-risk vault. --- Why Chaos Typical self-hosted chat Signal-class E2EE Chaos --- --- --- --- You run the servers Yes No Yes Operator can read messages Usually yes No No Groups, files, voice, desktop Yes Constrained Yes Per-device keys, Safety Number Rare Yes Yes Outbox + durable reconnect Sometimes Yes First-class Independent crypto audit Varies Yes Not yet The interesting problem is not “encrypt a string”. It is: encrypt for every device, survive at-least-once delivery, recover after a disconnect, and still refuse to trust a silently rotated identity key. --- Product Capability Web Desktop Status --- --- --- --- Direct chats, groups, saved messages Yes Yes Shipped Replie","default_branch":null,"files":null,"tree":[],"storefront":"/r/vaazhen","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/vaazhen/chaos-e2ee-messenger/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
