  message: >-
    By default, AWS SecretManager secrets are encrypted using AWS-managed keys.
    However, for added security, it's recommended to configure your own AWS KMS encryption key to protect your secrets in the Secret Manager.
    You can either create a new aws_kms_key resource or use the ARN of an existing key in your AWS account to do so.
