AEStego vs MaScanner

AEStego — Secure Image Steganography AEStego allows you to securely embed data inside images using advanced steganographic techniques and AES-256 encryption. Keep sensitive information concealed within ordinary photos while maintaining image quality and full offline privacy. Unlike simple “hide text” apps, AEStego is built for serious privacy. It combines authenticated AES encryption, compression, and structured data integrity verification to ensure your embedded content remains secure and tamper-resistant. Advanced Encryption • AES-256-GCM authenticated encryption • Optional hardware-bound Secure Enclave mode • Hybrid key derivation for strong password protection • Integrity verification with SHA-256 validation Your data remains encrypted and authenticated before being embedded. Professional Steganography • Pseudorandom bit distribution • Lossless PNG and TIFF support • Automatic JPEG conversion to lossless format • Capacity validation before embedding • No visible image distortion The carrier image remains visually unchanged while securely holding your data. Smart Compression • Compression applied before embedding • Works with encrypted and unencrypted payloads • Reduces detectable patterns • Efficient storage inside images Embed Text or Files AEStego supports embedding: • Text messages • Documents • PDFs • Images • JSON • ZIP files • Any binary file Extracted payloads are restored byte-for-byte with integrity verification. Secure Extraction • Detect embedded payloads • Automatic structure validation • Password-protected extraction (if encrypted) • Save or share recovered data • Integrity and authentication verification If an image does not contain valid embedded data, AEStego safely reports it. Privacy First • 100% offline operation • No tracking • No analytics • No cloud dependency • No account required Your data never leaves your device. Designed for Professionals AEStego is ideal for: • Privacy-conscious users • Security researchers • Journalists • Developers • Digital security enthusiasts Clean interface. Technical accuracy.

MaScanner makes scanning QR codes and barcodes simple. Scan with your camera, read QR codes from saved photos, keep your results organized in one place, add notes to scans and export data anytime. SCAN YOUR WAY • Scan QR codes and common barcode formats with your camera. • Use Batch mode to capture multiple codes in one session. • Read QR codes from images in your photo library. • Use camera zoom and the flashlight for difficult-to-read codes. • Choose sound and vibration feedback for successful scans. • Add a private note to any saved scan. Notes are saved on the device, appear in History, are searchable, and are included in CSV exports. MAKE RESULTS USEFUL • Recognize website links, Wi-Fi details, email addresses, phone numbers, SMS, product codes, and plain text. • Copy or share scanned information. • Export the complete scan history to a CSV file, or select specific scans and export only those items. KEEP THINGS ORGANIZED • Revisit saved scans in your history. • Search and filter past results. • Mark frequently used scans as favorites. • Swipe right on a History item to reveal its Delete action. The app asks for confirmation before removing the scan. LOCAL BY DESIGN Your scan history stays on your device. No account is required, and MaScanner has no analytics or cloud sync. Supported camera formats include QR, Aztec, EAN-8, EAN-13, UPC-A, UPC-E, PDF417, Data Matrix, Code 39, Code 93, Code 128, ITF-14, and Codabar, where supported by your device. Scanning saved images on iPhone supports QR codes. Opening websites and searching for products requires an internet connection.
