# Protecting Your Data with a Password (CPP)


In order to protect your source code and content, you are recommended to use the *[Archiver](../tools/archiver/index.md)* tool to archive your resources into UNG archives. It implements data encrypting to avoid unauthorized access and provides a password protection.


To protect resources, you need to create an archive with the password specified and pass the same password on engine initialization. The workflow is as follows:


- Create an [UNG archive](../tools/archiver/index.md#usage) with the specified password. For example, to create an archive named `files.ung` with the 12345 password that contains the `textures` directory, pass the following CLI: ```bash ung_x64 -o files.ung -d textures -p 12345 ```
- Specify the same password to be passed on [engine initialization](../api/library/engine/class.engine_cpp.md#init_parameters) in the `<your_project_name>.cpp` file: ```cpp #include <UnigineEngine.h> #include "AppSystemLogic.h" #include "AppWorldLogic.h" #ifdef _WIN32 int wmain(int argc,wchar_t *argv[]) { #else int main(int argc,char *argv[]) { #endif Unigine::Engine::InitParameters init_params; init_params.window_title = "Your_Title"; init_params.project = "<your_project_name>"; init_params.password = "12345"; Unigine::EnginePtr engine(init_params, argc, argv); AppSystemLogic system_logic; AppWorldLogic world_logic; engine->main(&system_logic,&world_logic); return 0; } ``` > **Notice:** If you pass a project name during engine initialization, this means the engine will store its rewritable data (such as logs, cache and configuration files) in user profile (in `C:\Users\<username>` on Windows or in `/home/<username>` on Linux) rather than `<UnigineSDK/bin/` or `<UnigineSDK/data/` folders. On engine initialization, you can set ***NULL*** to the *project* attribute of initialization parameters, if you don't need that data is stored in user profile: ```cpp // engine initialization Unigine::Engine::InitParameters init_params; init_params.project = NULL; init_params.password = "12345"; Unigine::EnginePtr engine(init_params, argc, argv); ```
