Support arrays and arrays-of-objects

Example:

{
  "secrets": [
    {
      "id": 1,
      "secret": "..."
    },
    {
      "id": 2,
      "secret": "..."
    }
  ]
}

Want to have the secrets encrypted (but leave the ids in plain text, to be used in lookups and indices).

Alternatively, this could be implemented by supporting nested models, depending on the ORM.
