Unity use of HTTPS

Hi

I sent a question about encryption in Unity. I received the answer on the bottom. As my understanding it always uses https so it is using encryption. My question is, does it really always use https? Is it something required by Mono? and for what?

"Thanks for reaching out to us. The runtime portion of Unity for iOS and Android does contain APIs that make use of encryption. Unity has the Mono implementations of HTTPS (SSL/TLS), among others. All encryption besides HTTPS is only performed if the developer calls those encryption APIs."

thanks
