/*
 Simple demonstration using MongoDB Client-Side Field Level Encryption (local key version)
 Requires Community or (preferrably) Enterprise Shell and a MongoDB 4.2+ database
 Local, stand-alone, or Atlas MongoDB will all work.

 To use this, just open Mongo shell, with this file, e.g.:

  mongo --nodb --shell hello_world_shell_local.js

  # For a self-signed cert: mongo --tls --tlsCAFile /opt/mongodb/certs/ca.pem --shell hello_world_shell_local.js
