# About Shamir's Secret Sharing Scheme

Shamir's Secret Sharing is an algorithm in cryptography created by Adi Shamir. It is a form of secret sharing, where a secret is divided into parts, giving each participant its own unique part.

To reconstruct the original secret, a minimum number of parts is required. In the threshold scheme this number is less than the total number of parts. Otherwise all participants are needed to reconstruct the original secret.

## How to use

### Visual Studio Code Extension :

- Dart - Dart language support and debugger

### Updating launcher icon :

Add your Flutter Launcher Icons configuration to your `pubspec.yaml`
```bash
dev_dependencies:
  flutter_launcher_icons: "^0.8.0"

flutter_icons:
  android: true
  ios: true
  image_path: "assets/icon/icon.png"
```
From your command line:
```bash
# Install dependencies
$ flutter pub get

# Generate icons for android and ios
$ flutter pub run flutter_launcher_icons:main
```
In the above configuration, the package is setup to replace the existing launcher icons in both the Android and iOS project with the icon located in the image path specified above and given the name "launcher_icon" in the Android project and "Example-Icon" in the iOS project.
