Readiness

Post-quantum cryptography readiness

Post-quantum readiness is not a single tool purchase. It is a program: baseline inventory, HNDL quantification, framework-mapped evidence, scheduled re-scans, and remediation proof.

Superposition

Compare feasible plans before you collapse to one.

Phase

Feasibility first, then rank against the operational objective.

Measurement

Ranked plan, short why, and the metric behind the call.

Inventory before migration

You cannot migrate what you have not inventoried. Start with TLS endpoints, JWKS, SSH, STARTTLS, and third-party dependencies — then map findings to NSM-10, CMMC, or NIST IR 8547 tiers.

Start with the foundations curriculum at /learn/topics/quantum-crypto-foundations and the 4-week path at /blog/learning-quantum-crypto-4-week-path.

Quantify HNDL exposure

Use Mosca inequality (X + Y > Z) to determine whether ciphertext captured today may be readable before migration finishes. The HNDL hub at /q-day/hndl includes an interactive exposure estimator.

Assess → Monitor → Convert

Assess delivers baseline CBOM and signed PDF. Monitor catches crypto drift between audit cycles. Convert attaches re-scan proof to remediation items. See /journey for the full maturity model.
