🎮 Usage

Method 1: Interactive Mode (Recommended)

Simply run the executable and follow the interactive menu:

DecryptEACPayload.exe

The menu will guide you through:

1. Choosing between web download or local file extraction
2. Selecting a game from the configuration
3. Automatic processing and extraction

Method 2: Command Line

For direct file extraction:

DecryptEACPayload.exe <path_to_EAC.bin>

🔍 Finding Game IDs

To add new games or use custom configurations, you'll need the productId and deploymentId:

1. Navigate to your game's EAC folder:

   ..\[GameName]\EasyAntiCheat\
   

   Example: ..\Throne and Liberty\EasyAntiCheat\

2. Open Settings.json with any text editor

3. Look for the configuration:

   {
       "deploymentid": "278b7d6708d198db6305102c77abdf50",
       "executable": "TL\\Binaries\\Win64\\TL.exe",
       "hide_bootstrapper": "true",
       "hide_gui": "true",
       "productid": "21bf5373a3f1ebc9d1cbe14de40871b0",
       "requested_splash": "EasyAntiCheat/SplashScreen.png",
       "sandboxid": "9e11c91c1a3047c8e03369eb271f6f50",
       "title": "TL",
       "wait_for_game_process_exit": "false"
   }

4. Copy the productid and deploymentid values

5. Add to games.json or use in the console menu

📁 Output Files

The utility extracts the following components:

• EAC_Launcher.dll - The main launcher component
• EAC_Driver.sys - Kernel-mode driver
• EAC_UserMode.dll - User-mode module

Files are saved in the current working directory or a specified output folder.

🔧 Technical Details

How EAC Modules Work

Easy Anti-Cheat operates through a multi-stage process:

1. Module Download: The launcher downloads the encrypted EAC.bin module
2. Decryption: The binary is decrypted and loaded into memory
3. Component Extraction: Three main components are extracted:
   • Launcher DLL for initialization
   • Kernel driver
   • Usermode DLL
4. Driver Loading: The kernel driver is loaded for deep system integration
5. Process Protection: The usermode DLL is mapped into the game process

Module Structure

Each EAC.bin contains:

• Encrypted launcher library code
• Encrypted usermode library code
• Encrypted kernel driver code
