Start Your Post-Quantum Cryptography Migration Now

With post-quantum standards finalized, "harvest now, decrypt later" makes migration a today problem. A practical path: build a crypto inventory, prioritize long-lived secrets, and adopt hybrid key exchange.

Post-quantum cryptography stopped being a research topic once standards bodies finalized the first quantum-resistant algorithms. The threat isn't only in the future — an attacker can capture encrypted traffic today and decrypt it years from now once hardware catches up. For anything that must stay secret for a decade, that clock has already started.

Harvest now, decrypt later

Long-lived secrets are the exposure: health records, financial data, government communications, and firmware-signing keys that live in the field for years. If it must remain confidential well into the future, its protection needs to be quantum-safe today.

A pragmatic migration path

• Inventory: find every place you use cryptography — TLS, VPNs, signing, storage.
• Prioritize: start with the longest-lived and highest-value secrets.
• Go hybrid: combine a classical and a post-quantum algorithm so you're safe even if one is weakened.
• Stay agile: design for crypto-agility so algorithms can be swapped without re-architecting.

You can't migrate what you can't see. A cryptographic inventory is step zero of quantum readiness.

Hybrid key exchange is already available in modern TLS and VPN stacks, so most organizations can begin without waiting. In our own CloudLAN mesh we favor a hybrid handshake — classical plus post-quantum — so today's connections resist both current and future attacks.
