A secure data hiding system that combines AES-256 encryption with LSB steganography to protect sensitive information during transmission.
-
Military-grade Encryption 🔐
- AES-256-CBC with PBKDF2 key derivation
- Secure password hashing with 100,000 iterations
- Random salt and IV generation
-
Advanced Steganography 🖼️
- LSB (Least Significant Bit) embedding
- Automatic capacity calculation
- Header-based length encoding
- Multi-image format support (PNG, JPG, JPEG)
-
User-friendly Interface 💻
- Streamlit-based web UI
- Drag-and-drop functionality
- Real-time feedback
- Cross-platform compatibility
