Google is rolling out quantum-resistant HTTPS certificates in Chrome to future-proof the web
Google is rolling out quantum-resistant HTTPS certificates in Chrome, tackling a problem most people don't think about yet: quantum computers will eventually break the encryption that secures every website you visit. The clever part is how they're doing it — using Merkle tree proofs that keep the new certificates nearly as small as current ones (~64 bytes instead of the 2.5KB that quantum-safe crypto normally requires), so browsing doesn't slow down. It's already live-testing with Cloudflare on about 1,000 certificates, with a full quantum-resistant trust store planned for 2027.
