Introduction

Key management is the foundation of cryptographic security. Poor key management — hardcoded keys, weak rotation schedules, inadequate access controls — undermines even the strongest encryption algorithms. Modern key management systems (KMS) provide centralized, auditable key lifecycle management.

AWS Key Management Service

AWS KMS is a managed service for creating and controlling encryption keys. It integrates with most AWS services and provides FIPS 140-2 validated HSM-backed key storage.
