### Get Playready License

Source: https://github.com/ready-dl/pyplayready/blob/main/README.md

This Python snippet demonstrates how to load a device, open a CDM session, request a license challenge, send it to a license server, parse the response, and retrieve decryption keys. Ensure you have the necessary certificate and key files.

```python
from pyplayready.cdm import Cdm
from pyplayready.device import Device
from pyplayready.system.pssh import PSSH
from pyplayready.misc.revocation_list import RevocationList

import requests

device = Device.load("C:/Path/To/A/Device.prd")
cdm = Cdm.from_device(device)
session_id = cdm.open()

pssh = PSSH(
    "AAADfHBzc2gAAAAAmgTweZhAQoarkuZb4IhflQAAA1xcAwAAAQABAFIDPABXAFIATQBIAEUAQQBEAEUAUgAgAHgAbQBsAG4AcwA9ACIAaAB0AH
```

### Create Playready Device

Source: https://github.com/ready-dl/pyplayready/blob/main/README.md

Create a Playready Device (.prd) file using your bgroupcert.dat and zgpriv.dat files.

```shell
pyplayready create-device -c bgroupcert.dat -k zgpriv.dat
```

--------------------------------

### Export Playready Device

Source: https://github.com/ready-dl/pyplayready/blob/main/README.md

Export a provisioned Playready device (.prd) back into its raw .dat files.

```shell
pyplayready export-device DEVICE.prd
```

--------------------------------

### Test Playready Device

Source: https://github.com/ready-dl/pyplayready/blob/main/README.md

Test a Playready device file (.prd) to verify its integrity and functionality.

```shell
pyplayready test DEVICE.prd
```

### Send License Challenge and Parse Response

Source: https://github.com/ready-dl/pyplayready/blob/main/README.md

This Python snippet continues the license retrieval process by sending the generated license challenge to a specified URL and then parsing the received license response. It requires the `requests` library.

```python
response = requests.post(
    url="https://test.playready.microsoft.com/service/rightsmanager.asmx?cfg=(persist:false,sl:2000)",
    headers={
        'Content-Type': 'text/xml; charset=UTF-8',
    },
    data=request,
)

cdm.parse_license(session_id, response.text)

for key in cdm.get_keys(session_id):
    print(f"{key.key_id.hex}:{key.key.hex()}")

cdm.close(session_id)
```
