What Is Cryptographic Discovery and Inventory?
Cryptographic discovery and inventory is the practice of finding all the cryptography in use across an organization (algorithms, keys, certificates, libraries, and protocols) and recording it in a structured, maintained catalog such as a CBOM.
Cryptographic discovery finds where cryptography is used across code, certificates, keys, and network traffic, and inventory records it in a structured catalog, usually a CBOM. Together they give the visibility that post-quantum migration, crypto-agility, and compliance require. Discovery is continuous because environments change, and it extends well beyond certificate discovery to algorithms, keys, libraries, and protocols.
Key Takeaways
- Discovery finds cryptographic assets; inventory is the organized, maintained record of them.
- A full inventory covers algorithms, keys, certificates, libraries, and protocols, not just certificates.
- Discovery uses code scanning, certificate and key store inspection, and traffic analysis.
- It is run continuously because cryptography changes as systems change.
- It is the essential first step for posture management, crypto-agility, and PQC migration.
What is Cryptographic Discovery and Inventory?
Cryptographic discovery and inventory is the practice of finding all the cryptography across an organization and recording it in a structured catalog. Discovery locates the assets; the inventory, often expressed as a CBOM, organizes them. Together they answer the question that post-quantum migration, compliance, and crypto-agility all depend on: where is cryptography used, and what does it rely on?
What Gets Discovered
A full cryptographic inventory goes well beyond certificates.
| Asset type | Examples |
|---|---|
| Algorithms | RSA, ECDSA, AES, SHA-256, ML-KEM, ML-DSA. |
| Keys | Public and private keys, symmetric keys, key pairs. |
| Certificates | TLS, code signing, and device certificates. |
| Libraries | OpenSSL, BoringSSL, and other cryptographic libraries. |
| Protocols | TLS, SSH, IPsec, and their versions. |
How Cryptographic Discovery Works
Discovery uses several complementary techniques, because cryptography hides in many places:
- Code and binary scanning: Finds cryptographic calls, hard-coded algorithms, and bundled libraries.
- Certificate and key store inspection: Locates certificates, keys, and key material.
- Network traffic analysis: Identifies protocols and algorithm versions actually in use.
Findings are normalized into a single inventory. Because code and infrastructure change continuously, discovery is run on an ongoing basis, not once.
From Certificate Discovery to Full Cryptographic Discovery
Many organizations already run certificate discovery to find TLS certificates. Full cryptographic discovery extends that to algorithms, keys, libraries, and protocols in code and systems. That broader view is what post-quantum migration requires, because the quantum-vulnerable algorithms you need to replace are not only in certificates.
Why it Comes First
Cryptographic discovery and inventory is the foundation for everything that follows: cryptographic posture management, crypto-agility, and post-quantum migration. Without it, every later step is guesswork.
How Encryption Consulting Helps
CBOM Secure performs continuous cryptographic discovery across code, certificates, keys, and traffic, and compiles a CycloneDX CBOM you can act on. It is the starting point for posture management and PQC migration, backed by ISO/IEC 27001:2022 and SOC 2 certified practices.
Frequently Asked Questions
Cryptographic discovery is the process of finding all the cryptography in use across an organization, including algorithms, keys, certificates, libraries, and protocols. It scans source code, binaries, network traffic, certificate stores, and key management systems to build a complete picture of where and how cryptography is used.
Discovery is the act of finding cryptographic assets; inventory is the organized record of what was found. Discovery scans systems to locate algorithms, keys, and certificates, and the results are compiled into a cryptographic inventory, often expressed as a CBOM. Discovery is continuous, since environments change, and the inventory is kept current from it.
You cannot protect or upgrade cryptography you cannot see. Discovery reveals weak algorithms, expiring certificates, unmanaged keys, and quantum-vulnerable cryptography. It is the essential first step for post-quantum migration, crypto-agility, compliance, and reducing the risk of outages and breaches tied to cryptography.
It combines several techniques: scanning source code and binaries for cryptographic calls and libraries, inspecting certificate and key stores, and analyzing network traffic for protocols and algorithm versions. The findings are normalized into a cryptographic inventory. Because cryptography changes as systems change, discovery is run continuously rather than once.
Certificate discovery is a subset. It finds TLS and other certificates across an environment, which is valuable but covers only part of the picture. Cryptographic discovery is broader, also finding algorithms, keys, libraries, and protocols in code and systems. Many organizations start with certificate discovery and expand to full cryptographic discovery for PQC readiness.
