Cloak.Model
Use this module to track the kind of encryption a row in your database was encrypted with.
Usage
Add a binary field to your Ecto module. It should be indexed, so that you can easily query on it.
schema "table" do
field :encryption_version, :binary
end
You can then use
this module, specifying the :encryption_version
field as the one to store the value on:
use Cloak.Model, :encryption_version
The :encryption_version
field will then automatically be reset with the current value of Cloak.version/0
every time a row is inserted or updated.
