Prefacing by saying I'm a total noob to webdev.
I'm trying to move my personal portfolio site off of Squarespace and onto some sort of static hosting. Since I know nothing, I'm cobbling together hugo templates and using LightBox2 to show image galleries. The blog I'm referencing includes LightBox2 using this:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/lightbox2/2.11.1/js/lightbox.min.js" integrity="sha256-CtKylYan+AJuoH8jrMht1+1PMhMqrKnB8K5g012WN5I=" crossorigin="anonymous"></script>
I would prefer to not subject people viewing my page to any external tracking if I can avoid it. My page has zero tracking/analytics for this reason. I briefly tried downloading LightBox2 and directly including it instead, and was able to get it working mostly, but some things were broken that I would need to debug. Before I do that I was wondering, is this even a problem? Is including stuff from cloudflare cdn like this sketchy? It's possible I'm being overly paranoid but I have no idea.
That's why I hate the "give the government a master key" metaphor for weakening encryption. You aren't making a master key, you're making every lock worse. The "master key" is just knowing how to exploit the giant flaw you've now created in every lock, and if that knowledge escapes every lock is now worthless.
Knocking "shave and a haircut" now opens every door, let's hope nobody else figures that out! I know! we'll lock that information inside this "shave and a haircut" safe!
