cloak v0.7.0-alpha.1 Cloak.Fields.Map View Source
An Ecto.Type
to encrypt maps.
Configuration
You can customize the json library used for for converting the lists.
config :my_app, MyApp.Vault,
json_library: Jason
Usage
defmodule MyApp.Encrypted.Map do
use Cloak.Fields.Map, vault: MyApp.Vault
end
You should create the field with type :binary
. On encryption, the map
will first be converted to JSON using the configured :json_library
, and
then encrypted. On decryption, the :json_library
will be used to convert
it back to a map.
This means that on decryption, atom keys will become string keys.
%{hello: "world"}
Will become:
%{"hello" => "world"}
