README

This PHP Steganography Library provides a simple and versatile tool for embedding and extracting hidden messages within digital images. Steganography is the art and science of concealing information within other non-secret data to avoid detection.

This library supports the hiding of text messages within image files, utilizing LSB (Least Significant Bit) manipulation to embed information without perceptibly altering the visual appearance of the image.
