HIPAA-Compliant Patient Data Anonymization Pipeline

Create a Bash shell script that uses curl and jq to interact with a secure health data anonymization API. The script must automatically strip Personal Health Information (PHI) from JSON patient records, implementing AES-256 encryption for sensitive fields. Include robust error handling, logging to a secure syslog, and automatic rotation of anonymization keys every 24 hours. Ensure the script can process batches of 1000+ patient records with minimal computational overhead.
