HIPAA-Compliant Patient Data Anonymization Pipeline

Create a comprehensive Bash script that automatically anonymizes patient medical records by removing personally identifiable information (PII) from CSV and JSON files. The script must implement cryptographic hashing for patient IDs, redact specific fields like names and addresses, and generate a secure audit log. Ensure the script supports multiple input formats, handles large files efficiently, and maintains HIPAA compliance standards. Include error handling for corrupted files and logging mechanisms that track all transformation processes.
