The menu will appear two, the resources to be packaged into a prefab, select the resources, and then the menu custom Editor/save Scene2 Enter the name

The newly generated file, then select the newly generated file, click the menu custom editor/make Unity3d file to bytes file input name

Another file is generated, then click on the file, the menu named Editor/save Scene2, so that the package encryption is OK
