Binwalk Free MIT licensed · official support for 64-bit Linux github.com · 4 Oct 2026

Purpose: Binwalk identifies and can extract files and data embedded inside other files, with a primary focus on firmware analysis.
Implementation: Binwalk v3 is rewritten in Rust for speed and accuracy.
Signature scanning: The project’s signature list documents 111 supported signatures, 72 of which are extractable.
Entropy analysis: Binwalk can generate entropy graphs to help identify sections that may be compressed or encrypted.
Extraction: The quick start guide shows file extraction with the -e option and recursive scanning with -M.
Rust integration: Binwalk includes a library that can be integrated into other Rust projects.
Installation: The README lists Docker, the Rust package manager, and compiling from source as installation methods.
Known limits: Results depend on known signatures, and Binwalk requires at least as much free memory as the analyzed files’ size.
License: The repository is distributed under the MIT License, which grants permission to use, copy, modify, merge, publish, distribute, sublicense, and sell copies subject to its terms.
Security and warranty: The MIT license provides the software “AS IS” and disclaims warranties, including merchantability, fitness for a particular purpose, and noninfringement.
