By late October 2025, more than half of human web traffic to Cloudflare uses post-quantum cryptography. What it means, the threat it guards against, and what's still missing.
What a VPN is in plain terms, what it's for, and why WireGuard has become popular: simplicity, performance, and modern cryptography compared to older solutions.
Cloudflare proposes Web Bot Auth: legitimate bots and AI agents sign their HTTP requests with a cryptographic signature (RFC 9421), instead of being recognised by spoofable IPs or User-Agents.
NIST has selected HQC as a backup post-quantum algorithm for encryption, built on different math than ML-KEM. What it is, the problem it addresses, and why having an alternative matters.
Chrome enables hybrid post-quantum key exchange by default on desktop. Why it matters, what 'harvest now, decrypt later' means, and why some network gear breaks.
