CRYPTO AGILITY & POST-QUANTUM CRYPTOGRAPHY
Know where cryptography is used. Understand what depends on it. Test how it can change. keyONE connects cryptographic inventory, PQC readiness and practical integration in your PKI, HSM and application environment.
THE OPERATING CONTEXT
Harvest now, decrypt later describes collecting encrypted data today to decrypt it later using sufficiently capable quantum computers. The confidentiality lifetime of your information and the time needed for migration determine where preparation matters most. Crypto agility means being able to change algorithms, keys, certificates and cryptographic components in a controlled way. That requires knowing the applications, interfaces and providers that depend on them.
A clear inventory, tested feasibility and a migration path your teams can operate.
A CONTROLLABLE RESULT
The scope follows your environment and protection needs. Each result supports a concrete technical or operational decision.
Document algorithms, protocols, keys and certificates together with their applications, owners and dependencies. Where useful, structure the findings as a cryptographic bill of materials (CBOM); record coverage and remaining gaps.
Identify confidentiality requirements, long-lived information and technical barriers. Distinguish components that can be configured, upgraded or replaced from those that need individual development.
Test representative certificate chains, interfaces and applications against agreed criteria for interoperability, performance, recovery and operating behavior. Record supported combinations and limitations.
Define target architecture, transition stages, responsibilities, acceptance criteria and fallback paths. Technical evidence can support relevant PCI DSS and DORA work without being treated as a compliance guarantee.
THE APPROACH
We work from representative use cases and agreed acceptance criteria. Algorithm selection follows applicable standards, actual product support and the constraints of your environment.
Agree on services, data confidentiality lifetimes, critical dependencies and the decisions the project must support. Separate confidentiality risks from signature, identity and integrity requirements.
Combine available inventories, configuration and application analysis with targeted discovery. Connect technical findings to services, owners and suppliers; make unverified areas explicit.
Check PKI, HSMs, providers, libraries and protocol implementations for documented support and replaceability. Consider hybrid approaches where appropriate; validate actual interoperability in the planned environment.
Test the selected use case with realistic certificate, key and application lifecycles. Include failure behavior, recovery and operational acceptance, not only successful algorithm execution.
Implement agreed changes and, where necessary, individual providers, scripts or interfaces. Sequence rollout and fallback so existing dependencies remain manageable.
Document findings, decisions and test results. Assign ownership for inventory maintenance and recurring reviews; link relevant systems and suppliers to compliance records.
THE RIGHT FIT
PQC preparation and compliance work share useful technical evidence. Their requirements and responsibilities remain distinct.
Prepare changes across certification authorities, key storage, providers and consuming applications. Find compatibility limits before a production migration depends on them.
Prioritize environments where information must remain confidential for many years. Evaluate exposure and migration lead time rather than relying on a predicted quantum-computer arrival date.
Support inventory and review of cryptographic cipher suites and protocols, monitoring of their continued suitability and planning for cryptographic weaknesses. Scope and assessment remain with the responsible organization and assessor.
Map technical cryptographic dependencies to ICT services and suppliers. The DORA information register records contractual arrangements for third-party ICT services; it is distinct from the cryptographic inventory. We help connect the records and responsibilities.
