OpenVPN Protocol

OpenVPN is a widely-used VPN protocol that provides secure and reliable connections.

Adding OpenVPN protocol support

To start using it, set the Protocol field to the OpenVpn value from the Core.Model.Enums.Protocol enum when starting the VPN.

var sdk = new SDK();

// ...

var getLocationsRequest = new GetLocationsRequest
{
    AccessToken = loginResponse.AccessToken,
    Protocol = Core.Model.Enums.Protocol.OpenVpn,
};

var getLocationsResponse = await sdk.GetLocationsAsync(getLocationsRequest).ConfigureAwait(false);
var selectedLocation = getLocationsResponse.VpnCustomLocations.FirstOrDefault();

var getCredentialsRequest = new GetCredentialsRequest
{
    AccessToken = loginResponse.AccessToken,
    VpnNode = selectedLocation,
    WithCertificate = true,
    Protocol = Core.Model.Enums.Protocol.OpenVpn,
};

var getCredentialsResponse = await sdk.GetCredentialsAsync(getCredentialsRequest).ConfigureAwait(false);
// ...

When changing the VPN protocol, it's important to call the GetLocations and GetCredentials methods before invoking startVPN. This is necessary because by calling GetLocations and GetCredentials after changing the protocol and before starting the VPN, you ensure that your application has the necessary information (available nodes) and authentication details (credentials) to successfully establish a VPN connection using the desired protocol.
