Using the Rust Library

Binwalk API

Binwalk includes a library that can be integrated into other Rust projects.

You will need to install the following system dependencies:

sudo apt install build-essential libfontconfig1-dev liblzma-dev

Tip

Detailed API documentation can be found in Binwalk's Rust documentation:

cargo doc --open

Example

Step 1

Create a new Rust project:

cargo new my_project

Step 2

To use the latest release, add the following dependency to your project's Cargo.toml file:

binwalk = "3.1.0"

To build against the the latest master branch (possibly unstable), add the following dependency to your project's Cargo.toml file:

binwalk = { git = "https://github.com/ReFirmLabs/binwalk.git" }

Step 3

Edit your project's src/main.rs file:

use binwalk::Binwalk;
fn main() {
    // Create a new Binwalk instance
    let binwalker = Binwalk::new();
    // Read in the data you want to analyze
    let file_data = std::fs::read("/tmp/firmware.bin").expect("Failed to read from file");
    // Scan the file data and print the results
    for result in binwalker.scan(&file_data) {
        println!("{:#?}", result);
    }
}

Step 4

Build and run your project:

$ cargo run
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.06s
     Running `target/debug/my_project`
