Open Source Java Messaging Platforms

Smoke is an encrypting chat messenger for Android written in Java.

Smoke is known as the first mobile McEliece Messenger: https://tarnkappe.info/artikel/english/mceliece-messaging-smoke-crypto-chat-the-first-mobile-mceliece-messenger-published-as-a-stable-prototype-worldwide-279847.html

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.

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.

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.
