> Support for encryption of sensitive properties relies on configuration of the Sensitive Properties Key specified using {{nifi.sensitive.props.key}} in {{nifi.properties}}.  The default behavior of {{StringEncryptor}} allows for the key to be blank and falls back to a default value, logging a verbose error message indicating that an explicit key should be provided.
> The fallback to a default value for the Sensitive Properties Key should be removed and an exception should be thrown indicating that the property value is required.  Deployments that already have an explicit value will not be impacted.  Migration guidance for upgrading should include steps to encrypt the configuration using a new key.
> It may be worthwhile generating a random Sensitive Properties Key for new installations where there is no existing flow.  This would new standalone installations to run with a secure key without the need for manual steps.
