Expected Behavior

It would be great if there is a set multiplication function in Rego, something like:

a := {"a", "b"}
b := {"c", "d"}
c := multiply(a,b)
#c == {["a", "c"], ["a", "d"], ["b", "c"], ["b", "d"]}

Actual Behavior

Currently they rely on downloading lookup data over the internet; we should change them so that they either load it from a local file, or create a local server that serves the data over HTTP.

What are fetch providers?

FetchProviders are the components OPAL uses to fetch data from sources on demand.

Fetch providers are designed to be extendable, and you can easily create more fetch providers to enable OPAL to fetch data from your own unique sources (e.g. a SaaS service, a new DB, your own proprietary solution, ...)

[We have a guide on how to write new fetch providers](https:/

What would you like to be added:

The references to the MAGTAPE_TLS_SECRET environment variable should be removed and the documentation for the "Bring Your Own Cert" (BYOC) model needs to be corrected.

The BYOC model requires an annotation on the magtape-tls secret. Details are within the magtape-init code
