Open Source Messaging Platforms

Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. The video shows how you connect to your friend via their 1-time QR-code, in person or via a video link. You can also connect by sharing an invitation link. Temporary anonymous pairwise identifiers SimpleX uses temporary anonymous pairwise addresses and credentials for each user contact or group member. It allows to deliver messages without user profile identifiers, providing better meta-data privacy than alternatives. 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.

Briar is a messaging app designed for activists, journalists, and anyone else who needs a safe, easy and robust way to communicate. Unlike traditional messaging tools such as email, Twitter or Telegram, Briar doesn't rely on a central server - messages are synchronized directly between the users' devices. If the Internet's down, Briar can sync via Bluetooth or Wi-Fi, keeping the information flowing in a crisis. If the Internet's up, Briar can sync via the Tor network, protecting users and their relationships from surveillance.

Lanchat is a Client/Server instant messenger chat service for network/internet use. Builds upon the many features of modern IM environments while implementing some unique ideas. Supports text formatting, blocking/banning, direct connections and much more

Petoron P2P Messenger (P-P2P-M) Architecture: Pure P2P - no servers, no databases Key storage: Keys generated in memory, never stored, erased after use Metadata: Only IP and port exist during the session - everything else is encrypted & obfuscated Encryption: PQS v1.2 - PBKDF2-HMAC-SHA256 (200k), BLAKE2s-MAC, custom stream cipher + fake padding Authentication: BLAKE2s-MAC (16 bytes) - instant failure on any data change Packet obfuscation: --stealth mode - padding, hidden structures Connection: Direct peer-to-peer only Anonymity: No accounts, logins, or phone numbers Third-party access: Impossible without physical access to both peers during session History: No storage — all in RAM, wiped on close Message size: Limited only by RAM & MTU — no artificial limits External dependencies: None DPI/blocking resistance: Harder to detect, can be masked Autonomy: Fully offline until peers connect https://github.com/01alekseev/Petoron-P2P-Messenger

This project contain chat server and chat client/admin that works on Windows/Unix.. This is a Free software. Developed by Osama Mohammad Oransa, 2009,contain 3 parts : Chat Server ,Admin and Chat Clients, Based on Java RMI, will support XMPP soon.

The end goal of the FreeMess Project is to produce a cryptographically secure, pseudonymous, cross-platform peer-to-peer Instant Messenger service, piggybacking on FreeNet (http://freenet.sourceforge.net) as a distributed filesystem to hold user data.

No-Name Instant Messenger is a secure (strong cryptography), cross platform communications program that supports existing IM networks (AIM, Yahoo, ICQ, etc.).

Novel Insight Inner Circle is a message and file encryption tool for Windows. The software is developed in Java and requires 64bit Java JRE. The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.

This project is designed to create a secure instant messaging client that utilizes existing instant message frameworks such as AOL, Google Talk, Yahoo Chat, etc. Ultimately, the goal is to have a multi-network client.

Secure P2P Instant Messenger running on .NET Framework 2.0. Uses server to store user information (user name, password, email address, friends list, log in state, IP address) in encrypted form. Uses custom designed symmetric encryption algorithm.

The goal of this project is to develop a network protocol (Peer Instant Messenger Protocol, PIMP) that creates a distributed, peer-to-peer network for the transmission of instant messages, along with a graphical client that will allow users to access the

Secure Java Instant Messenger. Supports asymmetric key encryption of messages. will support multiple protocols (Jabber initially) and multiple UIs.
