    Signal Server

    Signal Server

    Server supporting the Signal Private Messenger applications on Android

    Signal Server is the official backend server component that supports the Signal Private Messenger ecosystem on Android, iOS, and desktop platforms, serving as the trusted message relay, contact discovery, and push notification hub while the clients handle end-to-end encryption. Built in Java and licensed under the AGPL-3.0 license, this server software handles protocols for delivering encrypted messages, synchronizing user metadata like public keys and push tokens, and providing REST and service APIs for the client apps to interact with. Although cryptographic operations and message confidentiality are managed by the client side using the Signal Protocol, the server ensures message routing, user registration, and group updates without having access to the decrypted contents. Its codebase is public to ensure transparency and auditability for a security-focused community willing to inspect how message metadata and delivery mechanisms are implemented.

    MEMZIT :: advanced messages

    MEMZIT :: advanced messages

    modifiable, predefined selection lists 4 clarity, efficacy, efficiency

    The problem: ICT-induced communication filters The solution: clear statements. mandatory. The result: No more reading between the lines A) the basic concept: On the client-side we make available: Three database (e.g. SQLite) populated drop-down-lists for: ------ QR: question repeat/ your appeal ("What do I think what you are wanting from me") IM: I-message ("what do I think about this, what is my situation, my point of view, my feelings") AP: my appeal ("what exactly do I want you to do") ------ B) These statements are mandatory & are being sent together with the "normal", the factual part of the message. C) If the user makes a selection, it moves to the textfield where it can be modified. D) The system recognizes modifications immediately, and asks for "use once & discard" or "use & add to the list" E) This "communication-system" shall be made available for all major information-transmitting channels, like - email - whats up & other instant messenger
