TLS and HTTPS Internals is a course for developers, DevOps engineers, and anyone who wants to understand what’s actually happening behind the little lock icon in the browser’s address bar. No academic jargon, no 400-page RFCs, and no boring textbook diagrams. Instead, you’ll see the story of paypa1.com with a green lock, Maria sitting in a café using open HTTP, and DigiNotar collapsing within a month after being hacked. If you’re tired of googling “what is a cipher suite” every time something breaks — this course is for you.
