CAP Anonymizer Plugin

A CAP (Cloud Application Programming) plugin designed to anonymize fields based on @dbg.anonymize annotation. This plugin replaces sensitive property names on entities with generic values, ensuring data privacy and security.

Features

• Entity-Level Anonymization: Anonymizes entire entities if they are annotated with @dbg.anonymize annotation.
• Element-Level Anonymization: Replaces sensitive field values with generic placeholders.
• Logging: Logs the entities and fields that are marked for anonymization.
