One-off encryption?

Questions & Help Questions

Hi! I see two scenarios (sorry if I’m misreading your post):

  1. You do not care about the encoded information being read but just want to make sure it was not tempered with. In this case signing might be sufficient and you can use Phoenix.Token — Phoenix v1.8.8 or similar which is low-friciton if you’re already using phoenix.
  2. If you want the encoded data to be safe from prying eyes use something like GitHub - danielberkompas/cloak: Elixir encryption library designed for Ecto · GitHub which implements best practices around erlang crypto so you don’t need to worry about the details (like IVs). This is very close to "put these two options in your config/config.exs and then call these two functions”
