This JavaScript and PHP project allows you to encode data into an image and decode it back from the image. It provides a simple way to hide data within image files.
The decodeDataFromImage function decodes data from a base64-encoded image. It loads the image, extracts binary data from the least significant bits of the image's color channels, and converts it back to its original form.
The encodeDataInImage function encodes data into an image using PHP's GD library. It can either load an existing image or create a default one if no image is provided. By embedding data into the least significant bits of the image's color channels, it provides a creative way to hide information within images.
