**Description**
Currently types lacks proper encryption support.

**Proposed solution**
Add configurable encryption with sensible defaults.

**Priority**: Low/Medium

The issue names no files, tests, or entry points. First clarify whether the work concerns parser optimization for large datasets or configurable encryption for types; done should be defined as an agreed scope with sensible encryption defaults and validation criteria.
