IMPORTANT: AI is used in this project, so lets get that out of the way. im not sure how to quantify it. i use different AI models on different tasks in the code as well as the documentation. i dont want to mislead or inspire undue confidence in this implementation. its open-source for transparency. not ready for general use.
its always worth mentioning this project is far from finished and i hope with feedback i can make it better. i have put efforts towards directing it towards unit-tests, audit and formal-proofs. none of that is good-enough, but i hope they can compliment each other and can act as a starting point for verifying the implementation is correct. the functionality is built around the requirements of my project. it isnt professionally audited or reviewed. use responsibly.
my motivation on this project is that im mainly working on a p2p messaging app. i hope you can understand the pushback i get when i promote my messaging app as “secure”, so this transparency with the signal protocol is nessesary. im sure people have better things to do with their time than review unstable and unfinished code. i only put it out there for you to take a look if you’re interested. as a solo dev, there isnt anyone reviewing my code. if i dont share it like this, no one will come across it.
The implementation is in rust and compiles to WASM for browser-based usage.

- Demo: https://signal.positive-intentions.com/
The aim is for it to align with the official implementation (https://github.com/signalapp/libsignal). That version was not used because my use case required client side browser-based functionality and i struggled to achieve that in the official one where javascript is used but is targeting nodejs.
There are other nuances to my approach like using module federation, which led to me moving away from the official version.
This signal-protocol implementation is purpose-built for a p2p messaging app. i posted about it a couple months ago here: https://programming.dev/post/43579394
