HIPAA-Compliant Log Rotation for Medical Imaging Metadata

Design a bash script that implements secure log rotation for medical imaging metadata, ensuring HIPAA compliance. The script must: 1) Compress logs older than 30 days using 256-bit AES encryption, 2) Automatically delete logs older than 90 days, 3) Generate detailed audit trails with SHA-256 hash verification, 4) Support multiple DICOM and PACS storage directories. Include robust error handling and logging mechanisms that capture any potential data access or rotation failures.
