cloak v0.6.2 Cloak.EncryptedMapField View Source
An Ecto.Type
to encrypt maps.
Configuration
You can customize the json library used for for converting maps.
Default: Poison
config :cloak, json_library: Jason
Usage
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"}
You can use this field type in your schema
definition like this:
schema "table" do
field :field_name, Cloak.EncryptedMapField
end
