What is StegoCore

StegoCore is a high-performance steganography library for .NET 8. Hide secret data inside images using optimized algorithms with significant performance improvements.

What's New in v1.0.0

🚀 Major Performance Improvements

  • 4.6x faster LSB algorithm performance
  • 12.3x less memory allocation
  • Updated to .NET 8 with enhanced nullable reference types
  • ImageSharp 3.1.11 for the latest image processing optimizations
  • Comprehensive benchmarking infrastructure with BenchmarkDotNet

Getting started

StegoCore is using ImaheSharp as image processing library.

To hide some secret data inside an image do following:

byte[] secretData = System.IO.File.ReadAllBytes("secret.data");
using(var stego = new Stego("someimage.jpg"))
{
    stego.SetSecretData(fileBytes);
    Image<Rgba32> 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.

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:

stego.SetSettings(new StegoCore.Model.Settings
    {
        Key = "aaa"
    });
