kmsKeyId

The identifier of the KMS key to use for encryption of the volume copy. Specify a symmetric encryption KMS key. You can specify a KMS key using the key ID, key ARN, alias name, or alias ARN. If you set Encrypted to true but do not specify this parameter, the service uses the default KMS key for EBS encryption in your account. For cross-account volume copies, this must be a KMS key in the calling account.
