Add configuration options for encryption

**Description**
Currently models lacks proper pagination support.

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

**Priority**: Low/Medium

Start by reconciling the title, which mentions encryption, with the description and proposed solution, which discuss model pagination. No files or tests are identified, so clarify the intended scope and locate the relevant model and configuration entry points; done should mean the agreed behavior is configurable with sensible defaults.
