The KMS key identifier to use to encrypt the new elastic cluster. The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a cluster using the same Amazon account that owns this KMS encryption key, you can use the KMS key alias instead of the ARN as the KMS encryption key. If an encryption key is not specified, Amazon DocumentDB uses the default encryption key that KMS creates for your account. Your account has a different default encryption key for each Amazon Region.
