About SteganoCrypt
Advanced Image Steganography Suite
đ What is Steganography?
Steganography is the practice of concealing messages or information within other non-secret data. Unlike encryption, which makes data unreadable, steganography hides the very existence of the message.
SteganoCrypt uses LSB (Least Significant Bit) technique to embed data into the pixel values of images, making changes imperceptible to the human eye.
