Building a Cross-Platform Encrypted Search Engine: Tackling Browser Storage
2025-03-29
This article tackles the initial hurdle in building a cross-platform encrypted search engine: secure and efficient browser-side data storage. The author compares LocalStorage, IndexedDB, and the FileSystem API, ultimately choosing the FileSystem API for its file-system-like interface, better performance, and consistency with other platforms. The article details using Rust and web-sys to interact with the FileSystem API and implements an AES-GCM encryption layer for security. Finally, a unified `File` trait is created for managing both encrypted and unencrypted files.
