How quantum computers reshape cryptography

Cryptography is the ground under every online system. Quantum computing cracks that ground.

Today's encryption keeps your data safe, but today's standards are under real threat. A strong enough quantum computer breaks the math we trust now — RSA and elliptic curve, gone.

The clock

Attackers aren't waiting. They grab encrypted data today, store it, and decrypt later once quantum is ready. "Harvest now, decrypt later." Secrets from today can leak in the future.

What to do

• Know what crypto you run. (See Eon Insights.)
• Move to quantum-safe algorithms — ML-KEM, ML-DSA.
• Start now. Migration is slow; the threat isn't.

Move before the wave hits.

TL;DR — a cryptographically-relevant quantum computer breaks RSA and elliptic-curve crypto; "harvest now, decrypt later" makes today's captured data a future liability.

• At risk: RSA, elliptic-curve (ECDH/ECDSA).
• Migrate to: ML-KEM, ML-DSA (NIST PQC standards).
• Act now: migration is slow; the threat window is not.
• Start with discovery — see Eon Insights.
