The open-source, secure instant messaging protocol, developed by 3 hobbyists as a way to practice their chosen language, in order:

  • Spixa, working on c++ components (server, debug client & indev TUI client)
  • vivyir (a.k.a vivy_ir_), actively working on a minimalistic Rust gui client and maintaining a debugging utility also written in rust.
  • KasraIDK, planning to create an android client with Java.

openSIMP is an indev protocol built from the ground up with openness and security in mind, openness as in being able to implement your own servers and make your own clients with ease, after stabilizing the main server implementation (c++), a specification will be released as to what packets a server should be able to parse and send and the same thing for clients as well, encryption will be built in on both sides and is enforced.

This protocol was also created as a way to be based, knowing what every software that you're running is doing in the background and as such all of the officials implementations (the ones inside this very repository) are all licensed under an open source license and will stay that way forever.

Roadmap

  • (General) Make clients in C++, Rust and Java
    • C++
    • Rust
    • Java
  • (Rust client) Divide the client into a bin+lib crate and refactor
  • (Server) Add a console and commands
  • (Server) Add a name-system
  • (Server) Add more packets

Licensing

The openSIMP server, the clients and the debug utilities are all licensed under the Mozilla Public License, version 2.0.

opensimp's Issues

Fix empty messages

Empty messages sent from serverside are processed and broadcasted. since they are followed by two division bytes (\x01) it can cause issues. (following with previous unauthorized issues "too much data in stream" and "using division byte as message")

strip newlines from broadcasting

the openSIMP server accepts and broadcasts newlines if they're mixed in with normal text (testable with the susrust utility), proposed solution is to strip them before re-broadcasting since the messages themselves may contain valid data
