StegoSafe vs StegInsight

StegoSafe hides an encrypted secret inside an ordinary photo. The photo still looks like a photo — the secret rides in bits the eye can't see — so what you protect doesn't announce itself. Everything happens on your device. No account, no sign-in, no servers. Your secret and your password never leave your iPhone, iPad, or Mac. HOW IT WORKS • Type a secret — a recovery phrase, a password, a private note. • Pick a cover photo and choose how to protect it. • StegoSafe encrypts the secret and weaves it into the image. • Save the PNG, share it, or keep it. To read it back, open it in StegoSafe with your credentials. THREE WAYS TO PROTECT • Password — open it on any device, any time, as long as you know the password. • This device only — a key kept on this device behind Face ID / Touch ID. Nothing to phish out of you; nothing to recover if the device is lost. • Face ID / Touch ID + PIN — two factors. Opening needs both the device and a PIN you set. SPLIT ACROSS PHOTOS Break a secret into several share-images and set how many are needed to rebuild it — for example, any 3 of 5. No single photo reveals anything on its own. BUILT FOR PRIVACY • AES-256-GCM encryption, keys derived with PBKDF2-SHA256 (600,000 iterations). • Keep it as a PNG — re-compressing it (as chat apps do) is what destroys the hidden data, so StegoSafe helps you keep the real file. • Nothing is read from an image until you unlock it. A damaged or re-compressed image is reported as damaged — you're never handed a secret that's subtly wrong. IMPORTANT Only you can open your content. If you lose your password — or, for device-bound images, the device — it cannot be recovered, by you or by us. Write your password down somewhere safe. StegoSafe is for lawful, personal use.

Discover what lies beneath the surface of your digital images. StegInsight is a multi-platform tool for privacy enthusiasts and security-minded users to analyze and use steganography: hide or reveal text inside images. Key Features • LSB Steganography — Embed or extract hidden text using Least Significant Bit (LSB) encoding in pixel data. Supports UTF-8 text with a clear, consistent protocol. • LSB Bit-Plane Visualization — View the LSB layer of the red, green, and blue channels as grayscale images. Random noise suggests a normal image; regular patterns may indicate hidden LSB data. • Trailing Data Detection — Scan for data appended after the end of image files (EOF). See byte count, hex preview, and decoded text when the trailing data is valid UTF-8. Supports JPEG and PNG. • Dual Embedding Modes — Hide text in pixel LSBs or append it after the file’s logical end (EOF) for JPEG/PNG. Export results as PNG or save back to the photo library (iOS) or file. • Cross-Platform — Same core engine on iPhone, iPad, and Mac with a single, clean interface. • Learn — Built-in short guide to steganography, LSB and EOF concepts, and how to spot hidden content. Whether you’re learning how steganography works or checking whether an image carries hidden data, StegInsight gives you the tools to look under the surface.
