This is the project that allows to hide the information in messages from plain sight using the invisible Unicode characters \u200C and \u200D.
It consists of two submodules:
- Secret messaging Backend - WASM C++ binary that defines the encode and decode routines. They take the string as an input and convert its binary unicode represention into a new string that consists of
\u200Cas a logical1and\u200Das a logical0. - Secret messaging Frontend - Django program that just serves HTML's, CSS, WASM and JS files.
- This repo - deployment, used to host the whole app as a website.
Example: secret message resides right here.
To decode it, you can use the hosted website - pleasehide.it. Select "Reveal secret" and you will be able to decode the secret message.
Deployment consists of:
- Containerised Django application, with Uvicorn as an ASGI server. It also collects the static files to be later served by NGinx.
- Backend builder, that builds the required WASM binary and JS bindings. The resulting files are then mounted into the Django application container as static files.
- NGinx builder, that acts as a HTTP/HTTPS reverse proxy to the Django app. It also serves the static files to the user. I use Let's Encrypt to create HTTPS certificates.
