Protecting Your Data with a Password
In order to protect your source code and content, you are recommended to use the Archiver tool to archive your resources into UNG archives. It implements data encrypting to avoid unauthorized access and provides a password protection.
Protected packages are entirely loaded into memory, no data streaming is available for them.
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 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:
ung_x86 -o files.ung -d textures -p 12345
- Specify the same password to be passed on engine initialization in the <your_project_name>.cpp file:
#include <UnigineEngine.h> #include "AppSystemLogic.h" #include "AppWorldLogic.h" #include "AppEditorLogic.h" #ifdef _WIN32 int wmain(int argc,wchar_t *argv[]) { #else int main(int argc,char *argv[]) { #endif Unigine::EnginePtr engine(argc,argv, "<your_project_name>", "12345"); AppSystemLogic system_logic; AppWorldLogic world_logic; AppEditorLogic editor_logic; engine->main(&system_logic,&world_logic,&editor_logic); return 0; }
On engine initialization, you can pass NULL as the 4th argument if you don't need that data is stored in user profile: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.// engine initialization Unigine::EnginePtr engine(argc,argv,NULL,"12345");
