Add configuration options for encryption

**Problem**
When working with parsers, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

The issue title requests encryption configuration, while the body discusses parser error messages without naming files, tests, or an entry point. First clarify which scope is intended, then locate the relevant parser or configuration code. Done should mean the selected behavior is specified and covered by a reproducible test or documented verification.
