Extract ELF

About

Provides comprehensive technical guidance for parsing ELF headers and program headers to extract memory values into structured formats like JSON. It ensures accuracy by handling architectural differences between 32-bit and 64-bit files, managing little-endian and big-endian byte orders, and correctly zero-filling BSS sections where memory size exceeds file size. This skill is invaluable for low-level systems programming, binary analysis, and debugging tasks where mapping file data to virtual memory addresses is required.
