Add configuration options for analytics

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

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

**Priority**: Low/Medium

The issue names no files or tests. Start by locating the route-handling entry point and existing configuration options, then trace how routes are processed and where encryption would fit. Done means encryption can be configured and has sensible defaults, but the issue does not define the supported options or validation.
