MQTT serves as the push message pushing protocol for Android clients. The Android client needs to connect to the MQTT Proxy server via SSL/TLS for encrypted transmission of messages. Implementing this process requires two support, one for the MQTT protocol client and the other for the MQTT proxy server. There are many open-source Mqtt proxy servers, and I choose to use Mosquitto Broker.
Mosquitto install to Windows, I use Windows as the Mosquitto Prox
However, when I follow the steps above, the HTTPS service will not start, and the certificate file will always be prompted that it does not exist or the format is invalid. After a long time, I finally got it done. Here I will summarize it.

or the relevant nodes on the Internet are trustworthy, or the user believes that the encryption layer (TLS or SSL) of this protocol cannot be compromised by the listener.
So the key to deploying HTTPS protocol access is certificates. Below is a look at the classification of HTTPS certificates.
With the development of the Internet, it has been deeply in all aspects of people's lives, it can be said that we are inseparable from the Internet. In the face of human dependence, Internet security is increasingly important, personal privacy is increasingly needed to protect. How can we improve the security of our Internet access? How to protect the privacy of our internet? How to prevent being hijacked by hackers? And so on, many security factors need to be taken into account.HTTPS has gradua
