RAR extractor

This backend tool accepts a RAR archive and, when requested, extracts its contents to a target directory. It supports password-protected archives, multi-part archives, and both extraction and content listing modes. It validates input paths, verifies archive integrity, and returns structured outputs such as the list of extracted files, total size, and any errors. Users include data engineers, system integrators, and automation scripts that need access to archived data without client software. It is designed for server-side use, batch processing, and CI pipelines where reproducibility and detailed error reporting are critical.\n\nCore logic: On receiving inputs, the tool inspects the archive header to identify format, parts, and required password. It normalizes paths, prevents extraction outside allowed directories, and computes an extraction plan. It delegates actual extraction to a secure archive library capable of handling RAR variants, preserving file metadata where possible. If list_only is enabled, it returns a file manifest without writing to disk. Validation includes checking for missing password, unsupported compression methods, and corrupted archives. Outputs include extracted file paths, total bytes written, and a status code. Errors are conveyed using standard codes for integration in automated workflows.\n\nAudience and value: IT teams, data pipelines, and DevOps engineers benefit from predictable, scriptable extraction with clear error signals and minimal dependencies. Unique differentiators include password-aware extraction, comprehensive manifest generation, and strict path validation with safe defaults, enabling secure automation in cloud or on-prem environments.
