Frequently Asked Questions about Offline Mode
How does offline caching work?
CryptoViz registers a Progressive Web App (PWA) Service Worker. Clicking "Pre-cache" stores documentation, styles, scripts, and visualizer modules in your browser's Cache Storage so you can open CryptoViz anytime without internet access.
What are Single-File HTML Standalone Apps?
Single-File HTML Apps contain all documentation, formulas, and client-side JavaScript cipher execution code bundled into one file. You can download and run them on any device or USB drive in any modern web browser.
