Описание: 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 landscape
Key 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SSL is old-school, outdated and deprecated.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 expect:
Practical 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.
