How to use on-demand rotation for AWS KMS imported keys

Security Blog



AWS has announced on-demand rotation support for AWS Key Management Service (KMS) keys with imported key material. This new feature enables users to rotate cryptographic key material without changing the key identifier.

  • Allows importing multiple key materials into a single symmetric encryption key
  • Maintains the same key ID during rotation
  • Provides new API operations like RotateKeyOnDemand and ListKeyRotations
  • Adds key material identifiers to CloudTrail logs for improved auditability
  • Supports optional key material expiration up to 365 days

Key benefits include maintaining key identifiers, flexible rotation, audit trails, and metadata management. Pricing includes a base cost with additional charges for the first two rotations. The feature is available in all AWS Regions where AWS KMS is supported.
