 * You can obfuscate JSON blocks if you need to reference multiple values in your configuration YML file. Note that you may need to escape the quotation marks `""` with backslashes on Windows hosts. For example: `'{\"attribute\":\"value\"...`. In addition, use Powershell on Windows hosts, rather than the Command Prompt window, since the Command Prompt window can handle quotation marks in unexpected ways.
