The **HarmonyAppProvision** configuration file (also called profile) is the file where you declare permission and signature information for your application.
## Configuration File Internal Structure
The **HarmonyAppProvision** file consists of several parts, which are described in the table below.
| Name | Description | Data Type| Yes | Initial Value Allowed|
| version-code | Version number of the **HarmonyAppProvision** file format. The value is a positive integer containing 32 or less digits.| Number | Yes| No |
| version-name | Description of the version number. It is recommended that the value consist of three segments, for example, **A.B.C**. | String | Yes| No|
| uuid | Unique ID of the **HarmonyAppProvision** file. | String | Yes | No|
| type | Type of the **HarmonyAppProvision** file. The value can be **debug** (for application debugging) or **release** (for application release). The recommended value is **debug**.| String | Yes| No|
| issuer | Issuer of the **HarmonyAppProvision** file. | String | Yes | No|
| validity | Validity period of the **HarmonyAppProvision** file. For details, see [Internal Structure of the validity Object](#internal-structure-of-the-validity-object). | Object | Yes | No |
| bundle-info | Information about the application bundle and developer. For details, see [Internal Structure of the bundle-info Object](#internal-structure-of-the-bundle-info-object). | Object | Yes | No |
| acls | Information about the Access Control Lists (ACLs). For details, see [Internal Structure of the acls Object](#internal-structure-of-the-acls-object). | Object | No | Yes |
| permissions | Permissions required for your application. For details, see [Internal Structure of the permissions Object](#internal-structure-of-the-permissions-object). | Object | No | Yes |
| debug-info | Additional information for application debugging. For details, see [Internal Structure of the debug-info Object](#internal-structure-of-the-debug-info-object). | Object | No | Yes |
| app-privilege-capabilities | Privilege information required by the application bundle. For details, see the [Application Privilege Configuration Guide](../../device-dev/subsystems/subsys-app-privilege-config-guide.md). | String array| No | Yes |
An example of the **HarmonyAppProvision** file is as follows:
| developer-id | Unique ID of the developer.| String | Yes | No |
| development-certificate | Information about the [debug certificate](hapsigntool-guidelines.md).| Number | Yes if **type** is set to **debug** and no otherwise | No |
| distribution-certificate | Information about the [release certificate](hapsigntool-guidelines.md).| Number | Yes if **type** is set to **release** and no otherwise| No |
| bundle-name | Bundle name of the application.| String | Yes | No |
| apl | [Ability privilege level (APL)](accesstoken-overview.md) of your application. The value can be **normal**, **system_basic**, or **system_core**.| String | Yes | No |
| app-feature | Type of your application. The value can be **hos_system_app** (system application) or **hos_normal_app** (normal application). Only system applications are allowed to call system APIs. If a normal application calls a system API, the call cannot be successful or the application may run abnormally.| String | Yes | No |
### Internal Structure of the acls Object
The **acls** object contains the [ACL](accesstoken-overview.md) configured for your application. It should be noted that you still need to add the ACL information to the **reqPermissions** attribute in the application configuration file.
| Name | Description | Data Type| Mandatory | Initial Value Allowed|
| allowed-acls | [ACLs](../security/accesstoken-overview.md) configured for your application.| String array | No| No |
### Internal Structure of the permissions Object
The **permissions** object contains restricted permissions required for your application. Different from the ACLs set in the **acls** object, these permissions need user authorization during the running of your application. It should be noted that you still need to add the ACL information to the **reqPermissions** attribute in the application configuration file.
| Name | Description | Data Type| Mandatory | Initial Value Allowed|
| device-id-type | Type of the device ID. Currently, only the udid type is supported.| String | No | No |
| device-ids | IDs of devices on which your application can be debugged.| String array | Optional| No |
## Modifying the HarmonyAppProvision Configuration File
When a development project is created, the default application type is **hos_normal_app** and the default APL level is **normal**.
To enable the application to use system APIs, you need to change the **app-feature** field to **hos_system_app** (system application). To apply for high-level permissions, you need to modify fields such as **apl** and **acl**. For details, see [Access Control Overview](accesstoken-overview.md).
To modify the HarmonyAppProvision configuration file, perform the following steps:
1. Open the directory where the OpenHarmony SDK is located. (You can choose **File** > **Settings** > **OpenHarmony SDK** on the menu bar of DevEco Studio to query the directory.)
2. In the SDK directory, go to the **Toolchains** > {Version} > **lib** directory and open the **UnsgnedReleasedProfileTemplate.json** file.
3. Modify the related fields as required.
After modifying the configuration file, [sign the application](hapsigntool-guidelines.md).
