Automated Student Data Anonymization Script

Create a sophisticated Bash script that securely anonymizes student personal information across multiple CSV and JSON data sources for FERPA compliance. The script must: 1) Implement cryptographic hash replacement for sensitive fields like names and student IDs, 2) Preserve data integrity for research purposes, 3) Handle multiple file formats with error logging, 4) Generate an audit trail of anonymization processes. Include robust error handling and support for files up to 10GB with performance optimization.
