Application privileges are high-level capabilities of an application, for example, restricting an application from being uninstalled or restricting application data from being deleted.
OpenHarmony provides both general and device-specific application privileges. The latter can be configured by device vendors for applications on different devices.
OpenHarmony provides both general and device-specific application privileges. The latter can be configured by device vendors for applications on different devices. The privileges configured in the **install_list_capability.json** file take precedence over the privileges configured in the signature certificate.
Note: To avoid user dissatisfaction or even infringement, do not abuse application privileges.

### Configuration
### How to Configure
1. In the [HarmonyAppProvision file](../../application-dev/security/app-provision-structure.md), configure the general privileges in the **app-privilege-capabilities** field.
2. Use the signing tool hapsigner to sign the HarmonyAppProvision file and generate a **.p7b** file.
3. Use the **.p7b** file to sign the HAP.
1. Add the **app-privilege-capabilities** field to the [**HarmonyAppProvision** file](../../application-dev/security/app-provision-structure.md) to configure general privilege capabilities as required.
2. Use the hapsigner tool to sign the [**HarmonyAppProvision** file](../../application-dev/security/app-provision-structure.md) to generate a .p7b file.
3. Use the .p7b file to sign the HAP.
