# DRM

> **Note:** DRM is not supported on visionOS yet.

## Provide DRM data (only tested with http/https assets)

You can provide some configuration to allow DRM playback.
This feature will disable the use of `TextureView` on Android.

DRM object allows this members:

### `base64Certificate`

<PlatformsList types={['iOS']} />

Type: bool\
Default: false

Whether or not the certificate url returns it on base64.

### `certificateUrl`

<PlatformsList types={['iOS']} />

Type: string\
Default: undefined

URL to fetch a valid certificate for FairPlay.

### `getLicense`

<PlatformsList types={['iOS']} />

Type: function\
Default: undefined

Rather than setting the `licenseServer` url to get the license, you can manually get the license on the JS part, and send the result to the native part to configure FairplayDRM for the stream

`licenseServer` and `headers` will be ignored. You will obtain as argument the `SPC`
(as ASCII string, you will probably need to convert it to base 64) obtained from
your `contentId` + the provided certificate via `objc [loadingRequest streamingContentKeyRequestDataForApp:certificateData
contentIdentifier:contentIdData options:nil error:&spcError]; `

Also, you will receive the `contentId` and a `licenseUrl` URL defined as `loadingRequest.request.URL.absoluteString ` or as the `licenseServer` prop if it's passed.

You should return on this method a `CKC` in Base64, either by just returning it or returning a `Promise` that resolves with the `CKC`.

With this prop you can override the license acquisition flow, as an example:

```js
getLicense: (spcString, contentId, licenseUrl) => {
  const base64spc = Base64.encode(spcString);
  const formData = new FormData();
  formData.append('spc', base64spc);
  return fetch(`https://license.pallycon.com/ri/licenseManager.do`, {
    method: 'POST',
    headers: {
      'pallycon-customdata-v2':
        'd2VpcmRiYXNlNjRzdHJpbmcgOlAgRGFuaWVsIE1hcmnxbyB3YXMgaGVyZQ==',
      'Content-Type': 'application/x-www-form-urlencoded',
    },
    body: formData,
  })
    .then((response) => response.text())
    .then((response) => {
      return response;
    })
    .catch((error) => {
      console.error('Error', error);
    });
};
```

### `headers`

<PlatformsList types={['Android', 'iOS']} />

Type: Object\
Default: undefined

You can customize headers send to the licenseServer.

Example:

```js
source={{
    uri: 'https://media.axprod.net/TestVectors/v7-MultiDRM-SingleKey/Manifest_1080p.mpd',
}}
drm={{
      type: DRMType.WIDEVINE,
      licenseServer: 'https://drm-widevine-licensing.axtest.net/AcquireLicense',
      headers: {
          'X-AxDRM-Message': 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ2ZXJzaW9uIjoxLCJjb21fa2V5X2lkIjoiYjMzNjRlYjUtNTFmNi00YWUzLThjOTgtMzNjZWQ1ZTMxYzc4IiwibWVzc2FnZSI6eyJ0eXBlIjoiZW50aXRsZW1lbnRfbWVzc2FnZSIsImZpcnN0X3BsYXlfZXhwaXJhdGlvbiI6NjAsInBsYXlyZWFkeSI6eyJyZWFsX3RpbWVfZXhwaXJhdGlvbiI6dHJ1ZX0sImtleXMiOlt7ImlkIjoiOWViNDA1MGQtZTQ0Yi00ODAyLTkzMmUtMjdkNzUwODNlMjY2IiwiZW5jcnlwdGVkX2tleSI6ImxLM09qSExZVzI0Y3Iya3RSNzRmbnc9PSJ9XX19.FAbIiPxX8BHi9RwfzD7Yn-wugU19ghrkBFKsaCPrZmU'
      },
}}
```

### `licenseServer`

<PlatformsList types={['Android', 'iOS']} />

Type: string\
Default: false

The URL pointing to the licenseServer that will provide the authorization to play the protected stream.

### `type`

<PlatformsList types={['Android', 'iOS']} />

Type: DRMType\
Default: undefined

You can specify the DRM type, either by string or using the exported DRMType enum.
Valid values are, for Android: DRMType.WIDEVINE / DRMType.PLAYREADY / DRMType.CLEARKEY.
for iOS: DRMType.FAIRPLAY

### `contentId`

<PlatformsList types={['iOS']} />

Type: string\
Default: undefined

Specify the content id of the stream, otherwise it will take the host value from `loadingRequest.request.URL.host` (f.e: `skd://testAsset` -> will take `testAsset`)

## Common Usage Scenarios

### Send cookies to license server

You can send Cookies to the license server via `headers` prop. Example:

```js
drm: {
    type: DRMType.WIDEVINE
    licenseServer: 'https://drm-widevine-licensing.axtest.net/AcquireLicense',
    headers: {
        'Cookie': 'PHPSESSID=etcetc; csrftoken=mytoken; _gat=1; foo=bar'
    },
}
```

### Custom License Acquisition (only iOS for now)

```js
drm: {
    type: DRMType.FAIRPLAY,
    getLicense: (spcString) => {
        const base64spc = Base64.encode(spcString);
        return fetch('YOUR LICENSE SERVER HERE', {
            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
                Accept: 'application/json',
            },
            body: JSON.stringify({
                getFairplayLicense: {
                    foo: 'bar',
                    spcMessage: base64spc,
                }
            })
        })
            .then(response => response.json())
            .then((response) => {
                if (response && response.getFairplayLicenseResponse
                    && response.getFairplayLicenseResponse.ckcResponse) {
                    return response.getFairplayLicenseResponse.ckcResponse;
                }
                throw new Error('No correct response');
            })
            .catch((error) => {
                console.error('CKC error', error);
            });
    }
}
```
