Issue Description

Found a redundant Optional check in DefaultHashService class. The current implementation checks if Optional is present (isPresent()) before accessing its value, which is unnecessary as the subsequent method already safely handles null values.

Changes Made

• Removed redundant isPresent() check in DefaultHashService
• Simplified code flow while maintaining the same functionality

Rationale

This change improves code readability by avoiding unnecessary conditional checks without changing the behavior. Redundant Optional checks make the code more complex and potentially misleading.

Testing

Ran mvn verify to ensure basic checks pass. This change does not affect existing functionality, and all tests continue to pass.
