Amazon is pestering me about how my buckets are public, but they really aren't published anywhere so the bucket names and files should still be "private" until they are published somewhere, which they aren't.
I don't understand why this topic is never answered by anyone, not even Amazon. They over-explain it but never really outright say that you can pass the keys in the URL, or if the keys have to be embedded in the HTTP Request, etc. Then, getting BrightScript to do basic things is like an act of congress.
