About Quantum Shield

Quantum Shield checks whether the website you're currently visiting uses post-quantum-safe encryption (PQC), by sending the current site's URL to the Quantum Shield API (RedRuby Technologies) for verification. Why it matters: Classical encryption (RSA, ECC) will eventually be breakable by quantum computers. Quantum Shield gives you a quick, one-click way to see if a site has already adopted quantum-resistant algorithms — so you know your connection is future-proof. Features: - One-click check of the active tab's site - Clear quantum-safe / not quantum-safe indicator - Lightweight and fast, minimal impact on browsing Privacy: Quantum Shield sends only the current site's URL to the Quantum Shield API for verification. No other personal data, browsing history, or user information is collected or stored. Built by RedRuby Technologies.
