2. 공식 설치 스크립트

쉬움 추천

사전 준비물

APT (Debian/Ubuntu 계열) Debian/Ubuntu 계열 리눅스에 기본 내장된 패키지 매니저입니다.

sudo apt-get install openjdk-17-jdk zipalign

APT 패키지 저장소에서 바로 설치합니다 (Debian/Ubuntu 계열).

✅ 설치 후 새 터미널을 열고, 프로그램의 버전 확인 명령(예: --version)으로 정상 설치됐는지 확인하세요.

# About the project

This project is inspired by [amimo/dcc](https://github.com/amimo/dcc), which aims to make it easy for everyone to use this tool. We automated plenty of processes that you had to do manually in the original DCC. Moreover, we always try to add new features to make this tool more usable in real-world applications.
Check out <a href="#roadmap">Roadmap</a> to know about the changes we made and also the changes we are planning to make in the feature.

### Built with

* ![Python][Python-Badge]
* [![Androguard][Androguard-Badge]][Androguard_Repository]

# Installation

Python 3.8 or higher is required for running this tool. So, make sure your python is up-to-date.

1. Clone the repo.
   ```bash
   git clone https://github.com/codehasan/dex2c
   ```
2. Open the cloned directory.
   ```bash
   cd dex2c
   ```
3. Download **Apktool** latest version from [bitbucket](https://bitbucket.org/iBotPeaches/apktool/downloads/) and save it in `tools` folder with the name `apktool.jar`
   ```bash
   wget -O tools/apktool.jar https://bitbucket.org/iBotPeaches/apktool/downloads/apktool_2.10.0.jar
   ```
4. <a href="https://developer.android.com/ndk/downloads">Download</a> android NDK for your OS and extract it. Copy the folder path where `ndk-build` executable is located inside the extracted folder and configure `ndk_dir` in `dcc.cfg`

### Linux

![Linux](https://img.shields.io/badge/Linux-FCC624?style=for-the-badge&logo=linux&logoColor=black)

1. Install required dependencies.
   ```bash
   pip3 install -r requirements.txt
   ```
2. Install JRE/JDK & zipalign if you don't have it installed. The recommended JDK version is 17.
   ```bash
   sudo apt-get install openjdk-17-jdk zipalign
   ```

### Windows

![Windows](https://img.shields.io/badge/Windows-0078D6?style=for-the-badge&logo=windows&logoColor=white)

> [!NOTE]
> While this is supported on Windows, we strongly recommend using a Linux system for optimal compatibility and performance. If you're on Windows, consider using a Windows Subsystem for Linux (WSL) distribution to ensure a smoother and more reliable experience. The setup and instructions for WSL are the same as those for a [Linux](#linux).

1. Install required dependencies.
   ```bash
   pip3 install -r requirements.txt
   ```
2. Install JRE/JDK from <a href="https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html">oracle</a> if you don't have it installed. Search in Google, how to install JDK in Windows if you need more guidance on this topic. The recommended JDK version is 11 and up.
3. Make sure you've `zipalign` installed. You'll get it in Android SDK build-tools from <a href="https://developer.android.com/studio/releases/build-tools">here</a>. Add it to your system path.

### Termux

![Android](https://img.shields.io/badge/Android-3DDC84?style=for-the-badge&logo=android&logoColor=white)

One Step Installation: Run Below Command
   ```bash
   curl -L# -o termux_install.sh https://raw.githubusercontent.com/codehasan/dex2c/master/termux_install.sh && bash termux_install.sh
   ```
> NOTE: Some users have reported about installation errors with latest `clang` on termux. If you happen to face the same issue, then uncomment the lines stated in `termux_install.sh` and then proceed with the installation.

# Usage

### Filters

Add all your filters in `filter.txt` file - one rule for each line. Filters are made using regex patterns. There are two types of filters available in **Dex2c** - whitelist, and blacklist. You can use them whenever you need them.

#### WhiteList

- Protect just one method in a specific class.
```
com/some/class;some_method(some_parameters)return_type
```

- Protect all methods in a specific class.
```
com/some/class;.*
```

- Protect all methods in all classes under a package path.
```
com/some/package/.*;.*
```

- Protect a method with the name onCreate in all classes.
```
.*;onCreate\(.*
```

#### BlackList

Adding an exclamation `!` sign before a rule will mark that rule as a blacklist.

- Exclude one method in a specific class from being protected.
```
!com/some/class;some_method(some_parameters)return_type
```

- Exclude all methods in a specific class from being protected.
```
!com/some/class;.*
```

- Exclude all methods in all classes under a package path from being protected.
```
!com/some/package/.*;.*
```

- Exclude a method with the name onCreate in all classes from being protected.
```
!.*;onCreate\(.*
```

### Protect apps

- Copy your apk file to `dex2c` folder where `dcc.py` is located and run this command.

```bash
python3 dcc.py -a input.apk -o output.apk
```

- Run this command to know about all the other options available in dcc to find the best ones for your needs.

```bash
python3 dcc.py --help
```

# How to change lib name

Open `project/jni/Android.mk` file in the cloned directory. You will find a variable named `LOCAL_MODULE`, initially with the value `stub`. Please change it to your desired lib name. Keep in mind the following instructions to prevent possible errors.
- Don't use spaces in lib name, use hyphen `-` or underscore `_`
- Don't use any kind of symbols or punctuations in lib name other than underscores and hyphens
- Don't start the lib name with the text `lib` itself

# Roadmap

- [x] Add custom lib loader
- [x] Add new apksigner
- [x] Add multi-dex support
- [x] Add app abi handler
- [x] Add signature configuration in `dcc.cfg`
- [x] Add new options
    - [x] --skip-synthetic
    - [x] --custom-loader
    - [x] --force-keep-libs
    - [x] --obfuscate
    - [x] --dynamic-register
