Поддержка SSL в Qt 5.10

HTTPS, Qt 5.10

Всем привет. Очень сильно прошу помощи в подробной инструкции, как сделать поддержку https для моего приложения.
Мне просто по ссылке нужно скачать файлик и всё. Так как поддержки нету, то программа качает тот же файл, но внутри обычный html код.

Вот код приложения:

.pro

QT       += core gui network

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = DownloadEQFirmware
TEMPLATE = app

DEFINES += QT_DEPRECATED_WARNINGS

SOURCES += \
        main.cpp \
        mainwindow.cpp

HEADERS += \
        mainwindow.h

FORMS += \
        mainwindow.ui

mainwindow.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include <QUrl>
#include <QNetworkAccessManager>
#include <QNetworkRequest>
#include <QNetworkReply>
#include <QFile>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private:
    Ui::MainWindow *ui;

    QUrl urlStandard3N;
    QNetworkAccessManager *firmwareManager;

public slots:
    void downloadFirmware();
    void downloadFirmwareFile(QNetworkReply *reply);
};

#endif // MAINWINDOW_H

mainwindows.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    firmwareManager = new QNetworkAccessManager();

    connect(ui->btn_download, &QPushButton::clicked, this, &MainWindow::downloadFirmware);
    connect(firmwareManager, &QNetworkAccessManager::finished, this, &MainWindow::downloadFirmwareFile);
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::downloadFirmware()
{
    urlStandard3N = "http://www.eqdrive.com.ua/files/Updates/Standard3N/EQD4.6.0.1397.eqh";

    QNetworkRequest requestToUpdateStandard3N;          // Отправляемый запрос
    requestToUpdateStandard3N.setUrl(urlStandard3N);    // Устанавлвиваем URL в запрос
    firmwareManager->get(requestToUpdateStandard3N);    // Выполняем запрос
}

void MainWindow::downloadFirmwareFile(QNetworkReply *reply)
{
    if(reply->error()) {
        qDebug() << "reply error: " << reply->errorString();
    } else {
        QFile file("EQD4.6.0.1397.eqh");
        if(file.open(QFile::WriteOnly)) {
            file.write(reply->readAll());
            file.close();
        }
    }
}
