Description

Deep dive into TLS (previously called SSL) and HTTPS: Gain insights that set you apart from 99% of developers. Understand the true meaning of HTTPS beyond the surface-level claims of "security"The end of HTTP/1.1: Any serious developer today must concentrate on TLS security and hosting websites over the more robust protocols like HTTP/2 and HTTP/3. Stay relevant in a rapidly evolving digital landscapeKey Concepts Unlocked: Explore advanced topics such as hybrid key exchange, encryption, public key infrastructure (PIK), asymmetric and symmetric cryptography, TLS handshake, HMAC, signatures, hashing, and cipher suites. Each concept builds a solid foundation for your web security knowledge.This course is meticulously crafted for developers who are eager to elevate their TLS skills and gain a profound understanding of HTTPS, Certificate Authorities, and secure server configurations.SSL is old-school, outdated and deprecated. Therefore this course focuses on TLS as the protocol used with HTTP/2 and HTTP/3. What You'll Learn:Throughout this course, you will embark on an adventure that seamlessly blends theory with hands-on practice. Here's what you can expectractical HTTPS setup: You are going to learn how to use Node.js, and Live Server to set up a localhost server over a secure TLS / HTTPS connection. You will master the process of creating certificates and generating keys.Encryption: Understand the principles of encryption, including both symmetric and asymmetric methods, the concept of "keys" and how they are applied in secure HTTPS communications.TLS Handshake Mechanics: Dive deep into the TLS handshake process, learning how secure connections are established between clients and servers.Public Key Infrastructure: Learn about the framework that enables secure data exchange through digital certificates and key management.Advanced TLS Concepts and Cryptography: Gain insights into Hybrid Key Exchange (KEM algos), HMAC, signatures, hashing techniques, and cipher suites that form the backbone of secure TLS web interactions.This Course Is Practical: You'll put theory into action by setting up your own secure local server using HTTPS through the following steps:Create Your Own Certificate Authority (CA): Learn how to set up a CA from scratch, giving you the authority to issue certificates for your projects.Self-Sign Your CA Certificate: Discover how to self-sign your CA certificate, making it uniquely yours and ready for deployment.Generate Keys for Security: Master the process of generating private and public keys for your server.Request a Signed Certificate: Complete the setup by learning how to request a signed certificate, finalizing your secure server configuration.Sign Your Server's Certificate: Use your newly created CA to sign your server's certificate, ensuring secure communication for your local applications.Hands-On Experience:In this course you will spin up a localhost server (running on 127.0.0.1) over HTTPS using:Live Server in Visual Studio Code (we do this using a GUI and also OpenSSL)A Node server instance, using the mkcert library (I'll show you how to do this using the API and also the CLI)Additionally, you'll analyze traffic for both HTTP/2 and HTTP/3, gaining insights into modern web communication protocols. This course is not just about learning; it's about doing!Don't Miss Out on Essential Skills!In today's fast-paced tech landscape, mastering TLS and web security is no longer optional-it's essential. Every serious developer must be equipped with these skills to thrive in a competitive environment. The time to act is now! Equip yourself with the knowledge that will set you apart and position you as a leader in web development.This is your chance to step confidently into the future of web security with our comprehensive course on Transport Layer Security (TLS).So . what are you waiting for? Let's get crackin'
