Conceal hidden payload messages inside digital images (LSB), audio WAV waveforms, and zero-width unicode text with browser-based cryptographic privacy.
Cryptography scrambles the contents of a message so an eavesdropper cannot read it, but the existence of the secret message is obvious. Steganography conceals the very fact that a secret communication is taking place.
Steganalysis is the forensic science of detecting whether a digital file contains hidden information by analyzing pixel noise, color histograms, or high-frequency audio components.
