About

The Cipher Vision app is an image encryption and decryption tool designed to secure images using sophisticated steganographic techniques. It allows users to encrypt images with a password, making them unreadable to anyone who does not possess the correct key. The app also supports decryption, enabling users to restore their images to their original form. To use the app, users can upload an image by clicking on the designated area or dragging and dropping the file. Once an image is uploaded, users must enter a master key (password) to encrypt or decrypt the image. The app provides real-time feedback on the encryption or decryption process, including a progress bar and status messages. After processing, users can download the encrypted or decrypted image directly to their device. The app is built using modern web technologies, including TypeScript and React, and leverages the WebCrypto API for secure cryptographic operations. Key features include: 1. **Image Upload and Preview**: Users can easily upload images in various formats (PNG, JPG, WebP) and view them before processing. 2. **Encryption and Decryption**: The app employs advanced algorithms, including PBKDF2 for key derivation, YUV color space transformation, and tile scrambling, to ensure robust security. 3. **Steganographic Metadata Embedding**: Metadata is embedded within the image pixels, making it difficult to detect that the image has been encrypted. 4. **Local Processing**: All operations are performed locally in the user's browser, ensuring that images are not uploaded to any server, thus maintaining privacy and security. 5. **User-Friendly Interface**: The app features a clean and intuitive interface, with clear instructions and feedback throughout the encryption and decryption processes. 6. **Error Handling**: Users receive informative error messages if something goes wrong, such as incorrect passwords or unsupported file types. Cipher Vision is designed for users who require a secure method to share images without the risk of unauthorized access, making it suitable for personal and professional use.
