TLS & HTTPS Explained – Visualizations & Localhost Setup

О курсе

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this course, you will explore the essential concepts behind HTTP, HTTPS, and encryption protocols. You will gain a deeper understanding of how these technologies secure online communication, ensuring the confidentiality and integrity of data transmitted over the web. Through interactive examples and real-world applications, you’ll grasp key topics like symmetric and asymmetric encryption, public key infrastructure (PKI), and how to analyze encrypted traffic using Wireshark. As you progress through the course, you will get hands-on experience with tools like OpenSSL and XCA, learning how to generate certificates, set up secure servers, and work with HTTPS on a localhost. You will also explore advanced concepts, such as TLS 1.3, quantum computing implications on cryptography, and how to use Wireshark to analyze encrypted traffic. The course will guide you in setting up your own HTTPS server from scratch, equipping you with practical skills for the real world. This course is perfect for anyone looking to understand web security at a deeper level, especially developers, IT professionals, and network engineers. No prior knowledge of encryption is required, though a basic understanding of networking concepts will help you navigate the course more easily. It offers intermediate-level challenges with practical, hands-on exercises that will solidify your learning. By the end of the course, you will be able to explain how HTTPS works, set up a secure HTTPS server, capture and analyze encrypted traffic, and implement encryption techniques using tools like OpenSSL and Wireshark.
