Episode notes
Web App For Censorship Resistance
- Cryptee is a web app to avoid app-store dependence, enabling faster updates and censorship resistance.
- John Ozbay argues web deployment supports deniability and rapid security fixes compared with native app stores.
Eliminate Third-Party Scripts
- Avoid third-party scripts and services that can be subpoenaed or introduce unknown vulnerabilities.
- Build first-party tools for help desk, analytics, and admin to reduce external attack surfaces.
Photos Must Be Processed Locally
- Client-side processing is required for encrypted photo workflows: thumbnails, format conversion, and metadata stripping happen before encryption.
- This shifts heavy work to the browser so servers never see raw images or EXIF data.
