HTTPS and Web Security: Concepts, Handshakes, and Self-Assessments

Every time you visit a website, HTTPS works behind the scenes to keep data secure, yet many developers and IT professionals only have a surface-level understanding of how it actually functions. This text-based course bridges that gap by breaking down the core cryptographic principles, handshake processes, and modern security protocols that power the secure web, complete with written self-assessments to reinforce your learning. What you'll learn: 1. Understand the foundational differences between HTTP and HTTPS, including symmetric and asymmetric encryption. 2. Trace the step-by-step TLS handshake process, focusing on modern TLS standards. 3. Configure and manage SSL/TLS certificates, understanding the role of Certificate Authorities. 4. Implement modern web security headers like HTTP Strict Transport Security (HSTS) to prevent downgrade attacks. 5. Practice troubleshooting common HTTPS configuration errors and mixed content issues. 6. Evaluate your comprehension through structured, text-based self-assessment quizzes. You will start with the absolute basics of web cryptography before moving into detailed handshake mechanics, modern security headers, and practical certificate management. This course is designed for beginner developers, network enthusiasts, and IT students looking to solidify their web security fundamentals, with no prior encryption experience required. Start reading today to demystify HTTPS and confidently secure your web applications.
