Cloak.EncryptedMapField
An Ecto.Type
to encrypt maps.
Usage
You should create the field with type :binary
. On encryption, the map will first be converted to JSON using Poison.encode/1
, and then encrypted. On decryption, Poison.decode/1
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
