Add configuration options for sorting

**Feature request**
It would be great to have encryption for parsers.

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

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

Start by reconciling the title's sorting request with the body’s parser-encryption request, then locate the parser configuration and existing configuration options. The issue names no files or tests and does not define the encryption behavior, supported parsers, or verification criteria, so those requirements need clarification before implementation.
