Fast Facts
- Quantum migration is urgent: you can’t protect what you haven’t inventoried.
- Combine CA, network, cloud-key, and software data for a fast first inventory.
- Prioritize hidden cryptography in code, legacy devices, suppliers, and AI agents.
- Automate discovery, assign owners, and keep records current for crypto agility.
Start With What You Can See
A post-quantum migration begins with a basic question: Where does your organization use cryptography? It protects customer records, signs software updates and helps devices prove their identity. Yet many organizations lack a complete list.
Build a structured inventory. Record each algorithm, key length, system, business owner and dependency. Include certificates, encryption keys, software libraries, network protocols, SSH keys, API secrets and trusted certificates. A certificate list alone is not enough.
First, gather records you already have. Check certificate authorities, cloud key services, hardware security modules, network scans and software bills of materials. Then combine the results. A cryptographic bill of materials, or CBOM, can store the information in a format that tools can read.
Find the Risky Gaps
However, routine reports reveal only part of the picture. Algorithms may be hardcoded in software. Medical devices, factory equipment and older network hardware may be difficult to inspect or update. Suppliers may also rely on cryptography you cannot directly examine.
Prioritize by risk, not by the goal of finding everything at once. Start with systems holding sensitive data that must remain private for years. Attackers may collect encrypted information now and try to decrypt it later, when quantum computers are more capable.
Next, scan code and build systems for cryptographic libraries and settings. Ask suppliers about their algorithms and migration plans. Give each system a named owner. If you cannot verify a device or service, record that uncertainty instead of marking it complete.
Make the Inventory a Living Record
Quantum-resistant standards are advancing, while deadlines are approaching. At the same time, AI agents and other new services are creating credentials and connections quickly. So a one-time audit will soon be outdated.
Automate certificate exports and scans. Add cryptography checks to software development and purchasing. Require new products to explain how their algorithms can be changed. Review the inventory regularly and keep it in a shared, structured format.
This work takes effort, especially for older systems. Still, a clear inventory helps teams plan upgrades, protect long-lived personal and health data, and avoid rushed replacements. It also supports scientific progress: stronger security can help people use digital services with greater confidence in daily life.
