Cryptography and PQC Readiness: Build the Migration Path

Post-quantum readiness begins by knowing where trust and long-lived confidentiality depend on cryptography, then building a migration path the system can support.

8 minute guide · Updated August 29, 2026

Inventory trust, not algorithm names alone

Trace protocols, certificates, keys, signing, hashing, KMS and HSM use, secure updates, artifact integrity, vendor dependencies, and the systems that create, rotate, recover, or revoke trust.

Prioritize by exposure and constraint

  • Long-lived sensitive data and harvest-now-decrypt-later exposure.
  • Systems with limited crypto agility, long replacement cycles, or hard external dependencies.
  • Interoperability, performance, implementation, vendor, and operational constraints.
  • Migration waves, hybrid approaches, validation needs, exceptions, and accountable owners.

Turn readiness into a roadmap

Sequence immediate cryptographic remediation, crypto-agility work, vendor requirements, PQC transition, implementation validation, and release gates around the systems carrying the greatest consequence.
