GhostPixel 🕵️‍♂️

GhostPixel is a powerful and easy-to-use library for hiding files inside images using steganography. With GhostPixel, you can seamlessly embed data into image pixels while preserving visual quality and ensuring complete confidentiality.

✨ Features

• Data Hiding in Pixels: Embed files and messages directly into images using the least significant bits (LSBs) of pixels.
• Complete Confidentiality: Data remains invisible to the human eye and third-party tools.
• Support for Any File Type: Hide text files, documents, images, audio, and video.
• Ease of Use: Minimal code required for hiding and extracting data.
• High Performance: Fast processing even for large files and high-resolution images.
• Cross-Platform: Works on all platforms supported by Dart (Windows, macOS, Linux, iOS, Android).

🚀 Quick Start

Installation

Add GhostPixel to your pubspec.yaml:

dependencies:
  ghost_pixel: ^1.1.1

Then run:

flutter pub get

Usage

Hiding a File in an Image

import 'package:ghost_pixel/ghost_pixel.dart';

void main() async {
  await GhostPixel.hideFileInImage(
    imagePath: imagePath,
    filePath: filePath,
    outputImagePath: outputImagePath,
    compressFileBytes: true,
  );
  print('File successfully hidden in the image!');
}

Extracting a File from an Image

import 'package:ghost_pixel/ghost_pixel.dart';

void main() async {
  await GhostPixel.extractFileFromImage(
    imagePath: outputImagePath,
    outputFilePath: extractedFilePath,
    fileSize: File(filePath).lengthSync(),
    decompressFileBytes: true,
  );
  print('File successfully extracted from the image!');
}

Hiding a Bytes in an Image Bytes

import 'package:ghost_pixel/ghost_pixel.dart';

void main() async {
  final encryptedImageBytes = await GhostPixel.hideBytesInImageBytes(
    imageBytes: await FileUtils.getFileBytes(imagePath),
    fileBytes: await FileUtils.getFileBytes(filePath),
    compressFileBytes: true,
  );
  print('Bytes successfully hidden in the image Bytes!');
}

Extracting a Bytes from an Image Bytes

import 'package:ghost_pixel/ghost_pixel.dart';

void main() async {
  final decryptedFileBytes = await GhostPixel.extractBytesFromImageBytes(
    encryptedImageBytes: encryptedImageBytes,
    fileSize: File(filePath).lengthSync(),
    decompressFileBytes: true,
  );
  print('Bytes successfully extracted from the image bytes!');
}

🎯 Benefits

• Invisibility: Changes to the image are invisible to the human eye.
• Security: Data is protected from accidental detection.
• Flexibility: Supports any file type and image formats (PNG, JPEG, BMP).
• Simplicity: Minimal code required for integration into your application.

📦 Supported Formats

• Images: PNG, JPEG, BMP.
• Files: Text files, documents, images, audio, video, and other binary data.
