How to do Certificate-based authentication in React Native using Rest API?

Question

Hi
I want to do certificate based authentication in React Native, for that I am using Rest API.
And from the docs https://learn.microsoft.com/en-us/azure/iot-dps/how-to-control-access#certificate-based-authentication I found out this cURL, and I need to send certificate and key file in API, as https.agent is not supported by React Native, how can I manage to do that?

curl -L -i -X PUT –cert ./[device_cert].pem –key ./[device_cert_private_key].pem -H 'Content-Type: application/json' -H 'Content-Encoding:  utf-8' -d '{"registrationId": "[registration_id]"}' https://global.azure-devices-provisioning.net/[ID_Scope]/registrations/[registration_id]/register?api-version=2021-06-01

So far what I have tried is

 const data = {
    registrationId: registrationId,
  };
  const cert = await RNFS.readFile(certificatePath, 'utf8');
  const key = await RNFS.readFile(keyPath, 'utf8');
  console.log('cert', cert);
  console.log('key', key);
  try {
    const httpsAgent = new https.Agent({
      cert: cert,
      key: key,
      keepAlive: true,
    });
    console.log('httpsAgent', httpsAgent);
    const response = await axios({
      method: 'PUT',
      url: `https://global.azure-devices-provisioning.net/${scopeId}/registrations/${registrationId}/register?api-version=2021-06-01`,
      data: data,
      httpsAgent: httpsAgent,
      headers: {
        'Content-Type': 'application/json',
        'Content-Encoding': 'utf-8',
      },
    });
    return response.data;
  } catch (err) {
    console.log('err', err);
    return err;
  }

Thank you!!!

Hello @Shahanshah Alam,

welcome to this moderated Azure community forum.

The DPS is only applicable for pointing a device to an iot hub.

Only for that (one-time) provisioning, the Device Provisioning Service is used.

The DPS takes not part in the file upload.

If you use an SDK like documented here, the SDK takes all the security related logic away.
