 Hey, folks. Rob Dodson here, coming at you live from the Progressive Web App Summit here in Amsterdam. I am joined with Emily Schechter, a product manager for security on the Chrome team. Emily actually just got off stage. So we're actually in the sort of like the speaker green room. This is where everyone's getting prepared before they go and give their talks. Emily, you were talking about HTTPS and sort of the importance of moving over to that. If I'm someone who is not like a total networking pro, can you just tell me a little bit, like, what is the difference between HTTP and HTTPS? Yeah. So HTTPS actually means HTTP but over a secure connection. So basically with normal, non-secure HTTP, you actually don't get any of the security guarantees that come with HTTPS. So what that means is that with non-secure HTTP, anyone else on the network can actually see any of the data that you're sending and receiving back and forth. And you also don't actually know that the website you're trying to go to is the real website. So if you type HTTPS Google.com into your browser, you know that you're getting the real Google.com, not some fake Google.com. And you also know that the site that you see is the same site that they're sending to you. It doesn't have any sort of ad injection or malware injected into the page. Yeah. And I can tell I'm on that connection by the little green lock. Yeah, exactly. So there's the green lock we put in the URL bar in Chrome. It's in other browsers as well. Okay, cool. So if I'm a business and everything you just described sounds like something that would be super important to me as a business, I want to ensure that users are seeing my site and not some weirdo hacker thing. So if I'm a business and I want to move to HTTPS, is there any particular hurdle or thing that you think I might need to know ahead of time? Yeah. So what I actually talked about in my talk, my talk was called Mythbusting HTTPS. And HTTPS was invented, I think like 20 years ago. And at that time, you needed specialized server software and certificates, which are what you use to set up an HTTPS connection. They were really expensive and it was very sort of low performance. But over the past five, 10, 15 years, everyone has been really dedicated to improving the state of the union for HTTPS. So even though you might think there are these hurdles, actually now with HTTPS, you unlock some really crazy performance improvements so it's actually faster than HTTPS. And some of those services to maybe help give me on board things like SSLMate and there are others, right? Yeah. So there are a bunch of services out there that make it really easy for you today. One I want to talk about is called Let's Encrypt. And that's a new project that actually gives out free certificates and also provides a bunch of command line tools so that it makes certificate management and all that stuff super easy. All right. Well, that sounds pretty awesome. So we'll have Emily's talk on the Chrome Developers YouTube channel. We'll include a link down in the show notes. Also to those other resources, Let's Encrypt, SSLMate, et cetera. All those will be available down in the description. Emily, thank you so much for being with us today. Thank you. Thank you all for watching. I'm Rob from Amsterdam and I'll catch you later.
