Add rate limiting for encryption

**Feature request**
It would be great to have sorting for controllers.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_sorting` with default `false`.

First clarify the scope: the title requests encryption rate limiting, while the body requests controller sorting and an enable_sorting option. The payload names no files, tests, or entry points, so identify the relevant configuration and controller code only after the intended feature is confirmed; done should include agreed behavior and validation for the new option.
