Where do I put the generated file?

Save it as `robots.txt` at the root of your domain (e.g. `example.com/robots.txt`).

Does "Disallow all" hide my site from Google entirely?

It asks well-behaved crawlers not to index the site — it's not a security measure, and some crawlers ignore it.

Build an allow-all, disallow-all, or custom-rules robots.txt and copy it straight into your project.
