## What it is
unblob is an extraction suite that parses unknown binary blobs for 78+ archive, compression, and file-system formats, recursively extracting their contents and carving out unrecognized chunks. It provides both a command-line interface and a Python library, and is primarily aimed at firmware image analysis and reverse engineering.

## Use cases
- extract files from firmware images
- unpack unknown binary blobs
- recursively extract nested archives and filesystems
- identify embedded filesystems like SquashFS or JFFS2 in firmware
- carve out unknown data chunks from binary files
- analyze entropy of unknown regions to spot encrypted or compressed data
- generate JSON reports of extracted chunk offsets and metadata
- extend extraction with custom format handler plugins

## When to choose
- you need to extract and analyze firmware images or embedded device dumps
- you want accurate start and end offsets for chunks rather than naive carving
- you need recursive extraction across many archive, compression, and filesystem formats
- you want a Python library or CLI with a plugin system for custom formats
- you are doing data recovery, memory forensics, or malware analysis on binary blobs

## When to avoid
- you only need to extract a single well-known archive format like a plain zip or tar
- you require a GUI-based extraction tool
- you cannot install external extractor dependencies like 7zip, unar, or sasquatch
- you need Windows-native support without Docker or WSL
