Try an online implementation of this lib here:
https://papyruscompendium.dev/Widgets/Steganography
This is my own implementation of steganography, using a LSB (Least Significant Bit) method.
The way this works is by taking the LSB for every byte in a pixel (There are four in this case ARGB)
and changing the LSB to one bit of the data that you are trying to store. For example if I have
one byte of data I would like to store, I could store it in two pixels. I can store 4 bits
in one pixel without modifying the image enough that it is visible to the naked eye. In this
implementation I am only storing string data, but this can be made to store anything from files
to other images completely, like QR codes.
using System.Text;
using SixLabors.ImageSharp;
using SixLabors.ImageSharp.PixelFormats;
using Xunit;
namespace Steganography
{
class Program
{
static void Main(string[] args)
{
var encodedMessage = "This is an encoded message";
var stegoImage = new SteganographicImage(Image.Load<Rgba32>("TestImage.png"));
var encodedImage = stegoImage.EncodeDataInImage(Encoding.UTF8.GetBytes(encodedMessage));
stegoImage = new SteganographicImage(encodedImage);
var encodedData = stegoImage.GetEncodedDataFromImage();
Assert.Equal(encodedMessage, Encoding.UTF8.GetString(encodedData));
}
}
}If you encounter and bugs or issues, feel free to open an issue on GitHub. I will address these issues as soon as I can.
