Pocket Steganography

Hiding in Plain Sight. Pocket Steganography is a professional-grade security tool designed for journalists, researchers, privacy advocates, and security professionals who require more than just encryption. While standard encryption protects your data, it also announces that you have something to hide. Pocket Steganography solves this by embedding your encrypted files inside the invisible noise of standard WAV audio files. To the naked eye, and to standard media players, your file appears and plays as a normal audio track. THE PROFESSIONAL STANDARD Built with the Apple Human Interface Guidelines in mind, the app offers a modern, drag-and-drop interface on macOS, iPadOS, iOS and visionOS, powered by a robust, audit-ready steganography engine. CORE FEATURES: Dual-Layer Security: Your files are not just hidden; they are first encrypted. Even if the steganography is detected, the payload remains inaccessible without your password. AES-256 GCM Encryption: We use the industry standard for authenticated encryption, ensuring data confidentiality and integrity. LSB Encoding: Utilizing Least Significant Bit modification on 16-bit PCM WAV files ensures the audio carrier remains perceptually identical to the original. Cross-Platform Workflow: Start encoding on your Mac, drop the file via AirDrop to your iPhone, and extract it on the go. Go spatial on Apple Vision Pro. Drag & Drop Simplicity: An intuitive interface designed for rapid workflows. Data Sovereignty: 100% offline processing. No cloud, no servers, no tracking. Your keys are derived locally on your device. TECHNICAL SPECIFICATIONS: For those who demand to know what happens to their data: Carrier Format: RIFF WAVE (16-bit PCM). Steganography Method: LSB (Least Significant Byte modification of 16-bit samples). Key Derivation: HKDF-SHA256 with a unique salt constant. Cipher: AES-GCM (Galois/Counter Mode) for high-performance, authenticated encryption. Payload Structure: Length Header (32-bit Little Endian) + Encrypted Payload. IDEAL FOR: Secure Data Transport: Move sensitive documents across borders inside music playlists. Intellectual Property: Watermark audio assets with hidden ownership metadata. Private Archiving: Store backup keys or seed phrases inside your music library. PREMIUM MODEL Pocket Steganography is a one-time purchase for professional utility.
