retdec-rust

A Rust library and tools providing easy access to the retdec.com decompilation service through their public REST API.

You can either incorporate the library in your own tools:

extern crate retdec;

use retdec::{Decompiler, DecompilationArguments, File, Settings};

let decompiler = Decompiler::new(
    Settings::new()
        .with_api_key("YOUR-API-KEY")
);
let mut decompilation = decompiler.start_decompilation(
    DecompilationArguments::new()
        .with_input_file(File::from_path("hello.exe")?)
)?;
decompilation.wait_until_finished()?;
let output_code = decompilation.get_output_hll_code()?;
print!("{}", output_code);

or you can use the provided tool for stand-alone decompilations:

$ decompiler -k YOUR-API-KEY hello.exe

Either way, you get the decompiled C code:

//
// This file was generated by the Retargetable Decompiler
// Website: https://retdec.com
// Copyright (c) 2017 Retargetable Decompiler <info@retdec.com>
//

int main(int argc, char ** argv) {
    printf("Hello, world!\n");
    return 0;
}

Additionally, the crate provides access to the fileinfo service (analysis of binary files).

Status

Currently, the crate only provides very basic support for the decompilation and file-analyzing services. Support for more features is under way as the crate is under development.

A summary of all the currently supported parts of the retdec.com's API is available here.

Installation

To include the crate into your project so you can use it as a library, add the following lines into your Cargo.toml file:

[dependencies]
retdec = "0.1.0"

If you want to use the development version (current master branch), use these two lines instead:

[dependencies]
retdec = { git = "https://github.com/s3rvac/retdec-rust" }

If you just want to use the command-line tools (decompiler, fileinfo), install the project as follows:

cargo install retdec

Documentation

An automatically generated API documentation is available here:

• master (development version)
• 0.1.0 (latest stable version)

Contributions

Contributions are welcome. Notes:

• To generate API documentation, run

  cargo doc --lib --no-deps
  

• To run unit tests, execute

  cargo test --lib
  

• To run documentation tests, execute

  cargo test --doc
  

• To run all tests, including integration tests, execute

  RETDEC_API_KEY=YOUR-API-KEY cargo test
  

  Note: Before running integration tests, you need to set the RETDEC_API_KEY environment variable to your API key. Integrations tests communicate with the retdec.com's API, which is why a valid API key is needed.
