When will quantum computers break my website's encryption?

10-20 years for RSA-2048 breakers; HNDL makes it 'now' for long-lived data.

What is harvest now decrypt later?

Adversaries store your encrypted traffic today to crack with future quantum power.

How do I make Node.js quantum-resistant?

Use AES-256-GCM for symmetric; test ML-KEM/ML-DSA libs for keys/signatures; shorten token lifespans.

Quantum Crypto Clock: Web Devs, Start Counting Down From 'Harvest Now'

A Hacker News quantum crypto thread exploded with 289 upvotes, reminding full-stack devs that HTTPS isn't eternal. It's time to map risks to your Next.js deploys and JWT lifespans.

⚡ Key Takeaways

Quantum RSA breaks need 4,000 logical qubits—10-20 years away, but HNDL attacks start today. 𝕏
NIST's ML-KEM, ML-DSA ready; hybrid TLS rolling out in browsers, minimal dev lift. 𝕏
Risk ties to data lifespan: short JWTs safe, decade-long docs demand post-quantum swaps now. 𝕏
