Stego.Image is a client-side steganography tool that hides any file inside a PNG image using AES-256 encryption and LSB steganography, all running in the browser without any server interaction. It combines well-known cryptographic and steganographic techniques in a user-friendly web interface, making data hiding accessible to non-experts. While the concept is not novel, the implementation is solid and the privacy-focused architecture is a strong selling point.
Target audience: security enthusiasts, privacy-conscious users, developers
