In today’s digital world, encryption is the backbone of cybersecurity, protecting everything from financial transactions to personal data. But as organizations expand their IT environments, they often lose track of what cryptographic algorithms, protocols, and keys they have in place. This **lack of visibility** is a serious problem—especially with the looming threat of quantum computing, which could break many of today’s encryption methods. > A cryptographic inventory helps organizations regain control by identifying, categorizing, and assessing all cryptographic assets, making it an essential step in future-proofing security. ### What you should know: #### 1. Visibility into Encryption Mechanisms Most organizations use multiple encryption tools across different departments, applications, and devices. Without a clear inventory, some encryption mechanisms may be outdated or inconsistently applied. A cryptographic inventory uncovers all instances of encryption across an organization’s network, ensuring that no system is left unaccounted for. #### 2. Risk Assessment in the Quantum Era Quantum computing is expected to render many existing cryptographic protocols obsolete, particularly those based on RSA and ECC. By evaluating the strength and vulnerabilities of current cryptographic assets, organizations can identify weak points before they become security liabilities. This proactive approach ensures that businesses stay ahead of evolving threats. [[Factoring Large Prime Numbers (RSA)]] | [[Elliptic Curve Cryptography]] | [[Impact of QC on Cryptography]] #### 3. A Roadmap for a Secure Future Transitioning to quantum-resistant cryptography isn’t a simple switch—it requires careful planning. The National Institute of Standards and Technology (NIST) is actively developing post-quantum cryptographic (PQC) standards, but organizations must prepare now. A cryptographic inventory provides the foundation for a structured migration plan, helping businesses phase out vulnerable encryption methods in a strategic and manageable way. ### So What? Ignoring cryptographic inventory means **flying blind in an increasingly dangerous cyber landscape.** Without knowing what encryption is in place, organizations can’t assess their vulnerabilities, let alone prepare for the quantum shift. By taking inventory now, businesses gain the visibility they need to strengthen their security, mitigate risks, and confidently transition to post-quantum cryptography.
