Are We Prepared for Quantum Decryption? Time to Rethink Our Encryption Strategies

The Quantum Revolution: What's Happening?

As I immerse myself in Michio Kaku's fascinating book on quantum supremacy, I find myself reflecting on the robust advancements in quantum computing. Companies across the globe are investing heavily in this revolutionary technology, but what does this really mean for our encryption methods?

China’s Breakthrough: Time to Take Notice

You may have seen headlines about Chinese teams “cracking RSA.” The reality: researchers using D-Wave (a quantum annealer) have factored very small RSA-style numbers—think 22–90 bits in recent reports—not the 2048-bit keys used in production today. It’s interesting science, but not a practical break of modern cryptography. Independent coverage and experts have repeatedly cautioned against reading these claims as “RSA is dead today.”

Conservative industry estimates still put a cryptography-breaking, general-purpose quantum computer years away—we’re talking millions of high-quality, error-corrected qubits to threaten RSA-2048 or P-256. Even Google, after showing impressive quantum chips, says we’re not there yet. But the policy and standards clock is already ticking. That’s why the safest posture is parallel track: protect long-lived data now; prepare everything else to flip when the ecosystem is ready. Especially notice if your business data or IP can fall in the "harvest now, decrypt later" category, meaning data is actually stolen now, even if deemed worthless in the present, but can be potentially decrypted later that still means damage to your business.

When Should We Start Securing Our Algorithms?

The answer isn't straightforward. While it might seem premature to overhaul every encryption protocol at the first sign of quantum computing advancements, we need to start the conversation. Quantum decryption could potentially render many of our existing algorithms obsolete. As business owners and tech enthusiasts, we need to ask ourselves—when is the right time to rethink our encryption strategies? Is it when quantum threats become real, or should we act proactively?

Security agencies and serious tech companies suggest we should be looking into algorithms that are quantum-resistant. Solutions like lattice-based cryptography and hash-based signatures are gaining traction for their potential to withstand quantum decryption attempts. In an era where data security is paramount, exploring these options should be part of our tech conversations now.

A proactive approach means not only informing ourselves but also investing in future-proof technologies. As I am sure when a client commissions a new project, they think about the next 5 years, often due to budgets and planning the products actually get used for 10-15 years likely, instead of the initially planned term. While we may not need to switch all our encryption methods today, preparing for the capabilities of tomorrow can only be wise.

Industry leaders are already shipping defenses. In August 2024, NIST finalized the first three post-quantum cryptography (PQC) standards. Cloud providers and browsers have moved too. Cloudflare has been rolling out hybrid TLS handshakes (X25519 + Kyber/ML-KEM) at scale, and as of late 2025 reports that a majority of human-initiated traffic with Cloudflare uses post-quantum protection—a big milestone for “harvest-now, decrypt-later” mitigation. Chrome added hybrid PQC support starting with version 116 and has since updated code points as ML-KEM finalized.

Embracing Change in Encryption Strategies

As we plunge deeper into this quantum age, keeping abreast of developments is crucial. Whether you're a tech enthusiast like myself or a business owner looking to protect sensitive information, the conversation around quantum safety is becoming increasingly relevant. It’s not just about surviving today’s threats but anticipating tomorrow’s challenges.

In conclusion, the world of quantum computing is fascinating and full of potential. While there is a lot to learn—and we still don’t fully understand all its implications—we must start considering how these changes affect our encryption strategies. Let’s be curious, stay informed, and prepared for the quantum decryption era. Because in the tech world, staying one step ahead can make all the difference.
