Build a Complete Cryptographic Asset Register with CBOM

Ask most organizations a few simple cryptographic questions: How many certificates do we have? Where are our encryption keys stored? Which systems still rely on outdated algorithms? And the answers are often incomplete or based on assumptions rather than facts.

The challenge is that cryptographic assets are scattered across the enterprise. Certificates may exist on web servers, in applications, in cloud environments, in Active Directory, in containers, and in developer pipelines. Encryption keys can be stored in HSMs, cloud key management services, databases, or embedded within applications. Over time, this creates visibility gaps that make it difficult to understand what cryptography is being used, where it exists, and who owns it.

At the same time, the need for crypto visibility has become much more important. Organizations are moving more workloads to the cloud, compliance requirements continue to demand stronger control over cryptographic assets, and preparations regarding post-quantum cryptography (PQC) are pushing security teams to identify vulnerable algorithms and systems. Without a clear inventory, assessing risk or planning future cryptographic changes becomes extremely difficult.

This is where a Cryptographic Asset Register (CAR) comes in. A CAR is a centralized inventory of an organization’s cryptographic assets, including certificates, keys, algorithms, cryptographic services, and their associated metadata. Rather than relying on spreadsheets or disconnected tools, it provides a single source of truth to understand cryptographic usage across the environment.

More importantly, a Cryptographic Asset Register serves as the basis for effective cryptographic governance and quantum-readiness. Before organizations can secure, manage, or modernize their cryptography, they first need visibility into what they actually have.

What is a Cryptographic Asset Register?

A Cryptographic Asset Register (CAR) is a centralized inventory that tracks and documents all cryptographic assets used across an organization. Think of it as a complete record of the cryptography that supports your applications, infrastructure, services, and data protection efforts. Instead of relying on multiple tools, spreadsheets, or manual records, a CAR brings everything together in one place, making it easier to understand, manage, and protect cryptographic assets.

A well-maintained Cryptographic Asset Register should include a wide range of assets. This includes digital certificates used for authentication and encryption, public and private keys that establish trust, and cryptographic objects stored within Hardware Security Modules (HSMs). It should also track keys managed by cloud Key Management Services (KMS), along with secrets and tokens that applications use to access protected resources. Beyond assets themselves, a CAR should record the cryptographic algorithms and protocols in use, helping organizations identify outdated or vulnerable cryptography.

Maintaining a centralized inventory provides multiple benefits. It provides clear visibility into where cryptographic assets exist, who owns them, and how they are being used. It simplifies compliance and audit activities, supports certificate lifecycle management, and helps security teams identify risks before they become operational issues. Most importantly, it creates the visibility needed to support crypto-agility and forthcoming initiatives, such as the migration to post-quantum cryptography.

Why Most Organizations Lack Crypto Visibility?

For many organizations, cryptographic assets are everywhere—but visibility is nowhere to be found. Over the years, certificates, keys, secrets, and cryptographic services accumulate across multiple systems and teams, rendering it challenging to maintain an accurate inventory.

Today, cryptographic assets can be found across cloud providers, Hardware Security Modules (HSMs), Active Directory environments, business applications, containers, Kubernetes clusters, and CI/CD pipelines. Each platform often has its own management tools and processes, creating isolated pockets of cryptographic information. As a result, security teams rarely have a complete picture of what exists across the organization.

Another frequent challenge is shadow cryptography. Development teams may generate certificates, create encryption keys, or deploy cryptographic libraries without centralized supervision. Unmanaged certificates, forgotten keys, and undocumented cryptographic implementations can remain active for years without anyone realizing they exist.

Many organizations attempt to track these assets using spreadsheets or manual documentation. While this may work initially, cryptographic environments change constantly. New certificates are issued, keys are rotated, applications are deployed, and cloud resources are created every day. Manual records quickly become inaccurate and incomplete.

The lack of visibility can create serious problems. Security teams may miss weak algorithms, expired certificates, or unauthorized cryptographic assets. Audits become more difficult, compliance reporting takes longer, and planning for initiatives such as post-quantum cryptography becomes far more challenging. Without visibility, managing cryptography effectively largely becomes a guessing game.

The Fundamental Components of a Cryptographic Asset Register

A Cryptographic Asset Register is only as useful as the information it contains. Simply listing certificates and keys is not enough. To support security, compliance, operational management, and future cryptographic transitions, organizations need detailed metadata that provides context around each asset.

Asset Identification

Every cryptographic asset should have a unique identifier that distinguishes it from all others within the environment. The register should record whether the asset is a certificate, public key, private key, secret, token, or another cryptographic object. For certificates, capture details such as the subject name, issuer, serial number, and thumbprint. Ownership is equally important, as every asset should be linked to an individual, team, or business unit responsible for its management.

Cryptographic Information

The register should document the cryptographic properties of each asset. This includes the algorithm being used, such as RSA, ECC, AES, or ML-KEM, along with key sizes and cryptographic strength. Certificate-related information should include the signature algorithm and validity periods, helping teams identify assets that may be approaching expiration or demand replacement.

Operational Context

Knowing that an asset exists is useful, but understanding where and how it is used is even more valuable. The register should capture the asset’s location, whether it resides in an HSM, cloud KMS, a server, an application, or a container environment. It should also identify the business application, environment (development, testing, or production), and any dependencies that rely on the asset. This context helps organizations assess the possible impact of changes or failures.

Risk and Compliance Data

A contemporary Cryptographic Asset Register should also support risk management. It ought to flag weak or deprecated algorithms, identify expiring certificates, and track the status of post-quantum cryptography (PQC) migration. Mapping assets to regulatory and compliance requirements can further simplify audits and reporting while helping enterprises prioritize fixing efforts where they matter most.

Building a Cryptographic Asset Register: Step-by-Step

Creating a Cryptographic Asset Register starts with discovery. Organizations need to identify cryptographic assets wherever they exist, including HSMs, cloud KMS platforms, Active Directory, databases, file systems, applications, and source code repositories. Since cryptography is often distributed across multiple environments, relying on a single data source rarely provides a complete picture.

Once assets have been discovered, the next step is to normalize and correlate the data. Different systems may describe the same asset in different ways, making duplicate records common. Organizations should eliminate duplicates, link certificates to their corresponding public and private keys, and establish ownership relationships. This creates a more accurate inventory and helps security teams understand how assets are connected.

With a consolidated inventory in place, organizations can begin assessing cryptographic risk. This includes recognizing weak or deprecated algorithms, detecting certificate issues such as expiration risks, and evaluating exposure to upcoming quantum threats. Understanding where vulnerable cryptography exists helps prioritize correction efforts and supports enduring crypto-agility initiatives.

The final step is to keep the register updated through uninterrupted updates. A one-time audit provides only a temporary snapshot, while cryptographic assets are constantly being created, renewed, rotated, or retired. Automated discovery and monitoring ensure that the register remains accurate over time. By moving away from manual recording and periodic assessments, organizations can maintain a living inventory that supports security operations, compliance reporting, and post-quantum cryptography planning.

How CBOM Secure Automates Cryptographic Asset Management

Manually building and maintaining a Cryptographic Asset Register can be time-consuming and difficult to scale. Cryptographic assets are spread across multiple environments, ownership often changes, and new certificates and keys are constantly being created. This is where Encryption Consulting’s CBOM Secure helps organizations move from manual logging to automated cryptographic visibility.

Our CBOM Secure automatically discovers cryptographic assets across enterprise environments, helping organizations identify certificates, public and private keys, HSM objects, cloud KMS assets, secrets, and cryptographic dependencies. Rather than collecting information from isolated systems, it consolidates data into a single, centralized view of an organization’s cryptographic ecosystem.

At its core, our CBOM Secure constantly updates and maintains a Cryptography Bill of Materials (CBOM). This provides security and compliance teams with an accurate inventory of cryptographic assets, along with the metadata needed to understand how those assets are being used throughout the organization.

The platform goes beyond simple asset discovery through correlating related cryptographic objects through fingerprinting and relationship mapping. Certificates can be linked to their associated keys, ownership can be identified, and dependencies between applications and cryptographic assets can be established. This supplementary context makes the inventory significantly more valuable for operational and security decision-making.

Our CBOM Secure also helps organizations identify weak algorithms, aging cryptographic assets, and quantum-vulnerable cryptography that may require remediation. By providing a single source of truth for cryptographic governance, the platform enables better risk management, supports crypto-agility initiatives, and simplifies planning for post-quantum computing cryptography migration.

Rather than serving as another inventory tool, our CBOM Secure provides the practical foundation for a contemporary Cryptographic Asset Register, giving organizations the visibility needed to manage cryptography with confidence.

Preparing for Post Quantum Cryptography

For many organizations, post-quantum cryptography (PQC) migration may still seem like a future project. However, one of the biggest challenges is not deploying new algorithms—it’s understanding where existing cryptography is being used today. Before organizations can replace vulnerable cryptographic assets, they need a complete inventory of their assets.

This is why a cryptographic asset register is often considered the first step in any PQC migration strategy. Security teams need visibility into where RSA and ECC algorithms are present across their environment, which certificates depend on them, and which business-critical systems count on those cryptographic assets. Without this information, migration efforts can quickly become slow, costly, and prone to disruption.

A well-maintained Cryptographic Asset Register helps reduce migration complexity by providing clear insight into cryptographic assets, their relationships, and their current relevance. Teams can identify which systems to focus on, understand certificate dependencies, and assess the possible impact of replacing existing cryptography.

Our CBOM Secure eases this process through automated discovery and cryptographic risk analysis. By continuously identifying certificates, keys, HSM objects, cloud KMS assets, and cryptographic dependencies, it helps organizations locate quantum-vulnerable cryptography and understand where correction efforts are needed. This visibility enables a more structured approach to PQC planning, helping organizations make informed decisions and reduce uncertainty throughout the migration process.

Conclusion

Cryptography plays a key role in protecting applications, systems, communications, and sensitive data. However, organizations are unable to effectively protect cryptographic assets that they cannot see. Absent clear visibility into certificates, keys, algorithms, and cryptographic dependencies, managing risk becomes significantly more difficult.

A Cryptographic Asset Register provides the foundation needed to address this challenge. By building a centralized inventory of cryptographic assets and their associated metadata, organizations gain the visibility required for stronger governance, simplified compliance reporting, improved certificate management, and better preparation for postquantum cryptography. It enables security teams to understand what cryptography exists, where it is located, who owns it, and how it supports business operations.

The challenge is that manual approaches rarely keep pace with contemporary environments. Cryptographic assets are constantly being created, renewed, rotated, and retired across cloud platforms, HSMs, applications, containers, and development pipelines. Spreadsheets and periodic audits quickly become outdated, leaving visibility gaps that can introduce security and functional risks.

This is where our CBOM Secure makes a considerable difference. Through continuous discovery, cryptographic risk analysis, and centralized visibility, it helps organizations build and maintain a living Cryptographic Asset Register. Rather than relying on static inventories, security teams gain an accurate, continuously updated view of their cryptographic ecosystem, enabling well-informed decision-making, improved crypto governance, and a more seamless path toward forthcoming initiatives such as crypto-agility and the adoption of post-quantum cryptography.
