# What is StegoCore

StegoCore is steganography library for .NET Core. Hide secret data inside images using many algorithms.

[![Build and Test](https://github.com/paw3lx/StegoCore/actions/workflows/ci-build-and-test.yml/badge.svg?branch=master)](https://github.com/paw3lx/StegoCore/actions/workflows/ci-build-and-test.yml)

## Installation

StegoCore is available on [nuget](https://www.nuget.org/packages/StegoCore/) and [MyGet (dev build)](https://www.myget.org/feed/stegocore/package/nuget/StegoCore).

### Package manager

```bash

Install-Package StegoCore -Version 0.3.1

```

### .NET CLI

```bash

dotnet add package StegoCore --version 0.3.1

```

## Getting started

StegoCore is using ImaheSharp as image processing library.

To hide some secret data inside an image do following:

```cs

byte[] secretData = System.IO.File.ReadAllBytes("secret.data");

using(var stego = new Stego("someimage.jpg"))

{

    stego.SetSecretData(fileBytes);

    Image secretImage = stego.Embed(AlgorithmEnum.Lsb);

}

```

Pretty simple, right? :) Now you can save the image with secret. But how to extract secret from image? It's even simpler.

```cs

using(var stego = new Stego("secretImage.jpg"))

{

    byte[] secret = stego.Decode(AlgorithmEnum.Lsb);

}

```

Right now there are 2 steganography algorithms implemented:

- LSB (least significant bit)

- Zhao & Koch (algorithm based on DCT)

These algorithms can be parameterized. You can pass a key parameter, which will be used as random seed to determine where to hide secret data:

```cs

stego.SetSettings(new StegoCore.Model.Settings

    {

        Key = "aaa"

    });

```
