What service is primarily used for managing encryption keys in AWS?

The service primarily used for managing encryption keys in AWS is AWS KMS (Key Management Service). AWS KMS provides a secure and scalable solution for creating, storing, and managing encryption keys used to encrypt your data. It integrates with various AWS services, allowing users to easily encrypt data with minimal overhead, and it also facilitates the creation of customer-managed keys for compliance and regulatory needs.

KMS provides features such as key rotation, auditing, and access control, powered by identity and access management (IAM) policies, ensuring that only authorized users and services can use the keys. This level of control and security is critical for safeguarding sensitive information and maintaining compliance with industry standards.

While other services, like AWS Secrets Manager and AWS CloudHSM, offer valuable functionalities related to security—such as storing secrets or managing hardware security modules—the primary function of KMS is key management specifically, which is integral to encryption tasks across AWS environments.
