What Is Digital Key Management?

Digital key management refers to the processes and controls used to securely handle cryptographic keys throughout their lifecycle. These keys are fundamental to encryption, authentication, and secure communication across modern IT environments.

As organizations adopt cloud computing, automation, and remote access, the number of cryptographic keys grows rapidly. Without proper management, keys can become unmanaged, duplicated, expired, or forgotten—introducing significant security risks.

Effective digital key management provides visibility into where keys are used, enforces consistent security policies, and ensures keys are rotated and retired when no longer needed. It underpins technologies such as Public Key Infrastructure (PKI), SSH authentication, and machine identities, making it a foundational component of modern cybersecurity.
