disclaimer: I’m just asking to get understanding of the theory behind network traffic encryption, I know this doesn’t happen irl most likely.

Let’s take https connection for example. I like watching revolutionary things on youtube and do not wish for authorities to know what I am watching, we accept here for the sake of showcase that google won’t sell my watch history if asked (LMAO what am I even saying?).
So if I’m not mistaken since youtube has https implemented, our communication is encrypted, the keys are shared only between me and youtube. But when Youtube shares the key with me/my client the first time, is that also encrypted? Wouldn’t the same question keep getting answered until there is something unencrypted? I know this is a bit too much unlikely, but if ISP automated the process of gathering keys and decrypting web traffic for a certain site with them for all users, would that work for them?
I’m taking https here as an example, while I have the same question for like VPN.

    Bh sharing, unencrypted, on Lemmy that you like watching revolutionary videos on YouTube, the government now has that data, even if Google wasn’t going to give it to them. I thought I would just add that, as everyone else has explained asymmetric encryption well.

    Also, usually it’s just the content of the website, not the URL itself that is encrypted, so anyone, not just the government, can know what YouTube videos you watch (as the video ID is in the URL) as well as the URL of any other websites you visit.

      That’s not true. The original DNS request, for youtube.com, may not have been encrypted, but any URL parameters afterwards are kept encrypted. As long as HTTPS is used, if hypothetically Google wasn’t going to give it to them, “the government,” or your ISP for that matter, can tell you’re watching YouTube, but can’t tell which video you’re watching.
