U92

CLI tool for hiding files inside PNG images with integrity verification

Desktopfree

U92 is a free, open-source command-line steganography tool that embeds files and folders inside PNG images using least-significant-bit encoding, with automatic archive compression and lossless, integrity-checked extraction. It states plainly that steganography hides data rather than encrypting it, and recommends encrypting a payload separately first for stronger security. It's for security researchers and privacy-conscious users who need to conceal files inside ordinary-looking images.
