- **Crypto & Security** (`org.codelibs.core.crypto`, `org.codelibs.core.security`) - Basic cryptographic utilities, message digest operations, and secure random generation
- **XML Processing** (`org.codelibs.core.xml`) - XML DOM utilities, SAX parser helpers, and schema validation support
- **SQL Utilities** (`org.codelibs.core.sql`) - JDBC helper methods for result sets, prepared statements, and connection management
