#  HarmonyAppProvision Configuration File
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.

An example of the **HarmonyAppProvision** file is as follows:
```json
{
    "version-code": 1,
    "version-name": "1.0.0",
	"uuid": "string",
	"type": "debug",
	"validity": {
		"not-before": 1586422743,
		"not-after": 1617958743
	},
	"bundle-info" : {
		"developer-id": "OpenHarmony",
		"development-certificate": "Base64 string",
		"distribution-certificate": "Base64 string",
		"bundle-name": "com.OpenHarmony.app.test",
		"apl": "normal",
        "app-feature": "hos_normal_app"
	},
	"acls": {
		"allowed-acls": ["string"]
    },
	"permissions": {
		"restricted-permissions": ["string"]
    },
    "debug-info" : {
	    "device-id-type": "udid",
	    "device-ids": ["string"]
    },
    "app-privilege-capabilities":["AllowAppUsePrivilegeExtension"],
    "issuer": "OpenHarmony"
}

```


### Internal Structure of the validity Object

| Name   | Description                           | Data Type| Mandatory | Initial Value Allowed|
| ---------- | ------------------------------- | ------- | ------- | --------- |
| not-before | Start time of the file validity period. The value is a Unix timestamp, which is a non-negative integer.| Number   | Yes | No |
| not-after  | End time of the file validity period. The value is a Unix timestamp, which is a non-negative integer.| Number   | Yes | No |

### Internal Structure of the bundle-info Object

| Name                 | Description                           | Data Type| Mandatory | Initial Value Allowed|
| ------------------------ | ------------------------------- | ------- | -------- | --------- |
| 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 [**requestPermissions**](../quick-start/module-configuration-file.md#requestpermissions) 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 [**requestPermissions**](../quick-start/module-configuration-file.md#requestpermissions) attribute in the application configuration file.

| Name                 | Description                           | Data Type| Mandatory | Initial Value Allowed|
| ------------------------ | ------------------------------- | ------- | ------- | --------- |
| restricted-permissions | [Restricted permissions](accesstoken-overview.md) required for your application.| String array   | No | No |

### Internal Structure of the debug-info Object
The **debug-info** object contains debugging information of your application, mainly device management and control information.

| 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   | No | 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).
