Introduction 👋

Hey! This is our project app for Information Acquisition and Protection Engineering Course.

With this web application you can encrypt messages inside .bmp (example online converter to bmp) images and decrypt them back as you need it! We implemented this feature with three different algorithms so you can choose whichever you find best for your needs.

Development 🚧

The project is written in TypeScript. If you are coming from the JavaScript World, fear not! It's easier to setup than you think. All you have to do is to run the following command:

tsc

... in order to transcompile the .ts source code into .js runnable build.

There's only one requirement: the npm package manager and npm install -g typescript command ran at least once to install the TypeScript language.

Packages:

• Node Types:
  • It is used to make TypeScript aware of the Node.js API and provide type definitions.
  • npm i -g @types/node
