Bringing more transparency to post-quantum usage, encrypted messaging, and routing security

What this post added

This post introduces new security-related data sets and tools on Cloudflare Radar. It extends post-quantum (PQ) monitoring to origin-facing connections, allowing users to check any website's PQ encryption compatibility. A new Key Transparency section on Radar provides a public dashboard for real-time verification status of Key Transparency Logs for E2EE messaging services. Routing Security insights are expanded with global, country, and network-level information about ASPA deployment. The post details the methodology for measuring origin PQ support using an automated TLS scanner and the Go container leveraging the `crypto/tls` package. It also introduces a tool to test specific hostnames for PQ encryption support, which uses Cloudflare Containers and the Radar API.
