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
