**What is Key Management?**\
\
In Google Cloud Platform (GCP), Key Management refers to using **Cloud Key Management Service (Cloud KMS)** to manage cryptographic keys for your applications and services. Cloud KMS allows you to create, import, and manage keys securely in a centralized service. It integrates with other GCP services, providing a consistent way to encrypt data at rest, control access, and audit key usage across your cloud environment. Cloud KMS supports various key types and encryption algorithms, enabling you to protect sensitive data and comply with security requirements.
