NIST Releases Official Post-Quantum Cryptography Migration Guidance as Harvest-Now-Decrypt-Later Risk Grows
entrup · x · 2026-10-28
NIST has published official guidance for transitioning to post-quantum cryptography (PQC), warning that today's encryption protecting most sensitive data will not withstand future quantum computers.
Key points:
- The "harvest now, decrypt later" threat means the risk is already active, not futuristic
- Organizations should inventory encryption use across systems and critical suppliers, prioritizing key protection and digital signatures
- Vulnerable methods should be replaced with the PQC standards NIST finalized in 2024
- The report outlines timelines and migration activities for federal agencies and serves as a resource for organizations building quantum-readiness roadmaps, prioritizing data that must stay confidential for years
