Cryptographic inventory

What is a cryptographic inventory?

A cryptographic inventory is a complete and systematic record of all cryptographic assets used by an organization, including keys, certificates, algorithms, protocols, security modules, and encryption libraries. Its purpose is to provide full visibility into what is used, where it is deployed, by whom, and with what level of risk.

Why is it essential for businesses today?

Because in the era of quantum computing, current cryptographic algorithms may become obsolete and vulnerable. Having a comprehensive inventory allows organizations to plan the transition to post-quantum cryptography (PQC), comply with regulations, reduce exposure risk, and maintain control over their digital sovereignty.

How is an effective cryptographic inventory built and maintained?

It should follow a continuous process:

• Identify all cryptographic elements across infrastructure, applications, cloud environments, and devices.
• Assess their location, algorithm, key size, ownership, and lifecycle.
• Prioritize critical assets and begin preparations for migration to quantum-resistant algorithms.
• Maintain governance and procedures to keep the inventory up to date, automated, and aligned with the security strategy.
