kmsMasterKeyId

var kmsMasterKeyId: String?

Amazon Web Services Key Management Service (KMS) customer Amazon Web Services KMS key ID to use for the default encryption. This parameter is allowed if and only if SSEAlgorithm is set to aws:kms.

You can specify the key ID, key alias, or the Amazon Resource Name (ARN) of the KMS key.

  • Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab

  • Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

  • Key Alias: alias/alias-name

If you use a key ID, you can run into a LogDestination undeliverable error when creating a VPC flow log.

If you are using encryption with cross-account or Amazon Web Services service operations you must use a fully qualified KMS key ARN. For more information, see Using encryption for cross-account operations.

Amazon S3 only supports symmetric encryption KMS keys. For more information, see Asymmetric keys in Amazon Web Services KMS in the Amazon Web Services Key Management Service Developer Guide.
