 ## Overview
 
-[Context](../reference/apis/js-apis-inner-application-context.md) is the context of an object in an application. It provides basic information about the application, for example, **resourceManager**, **applicationInfo**, **dir** (application development path), and **area** (encrypted area). It also provides basic methods such as **createBundleContext()** and **getApplicationContext()**. The UIAbility component and ExtensionAbility derived class components have their own **Context** classes, for example, the base class **Context**, **ApplicationContext**, **AbilityStageContext**, **UIAbilityContext**, **ExtensionContext**, and **ServiceExtensionContext**.

-Encrypting application files enhances data security by preventing files from unauthorized access. Different application files require different levels of protection. For private files, such as alarms and wallpapers, the application must place them in the device-level encryption area (EL1) to ensure that they can be accessed before the user enters the password. For sensitive files, such as personal privacy data, the application must place them in the user-level encryption area (EL2).
