A default Rocket.toml comes with the binary. It contains sensible defaults but it is only meant for local execution!
These are the two configurations that must be defined in Rocket.toml if you're running on a shared HTTP server:
local = true
secret_key = "sTooPaHkmo2i/cXXwawBf4per11UBB1x7nRJvUxPfFg="This secret key is not really secret now, but it doesn't really matter if the app is only served on localhost. If you're running this app on a shared HTTP server, this key must be kept secret, as it ensures user's authentication and thus access to all the data.
There is also the local = true parameter, that basically disables user authentication, and makes every session's user the user with ID=0.
