It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

Alex Bush

Full Stack Engineer

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

Abbey Helterbran

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.

Dive deep into encryption techniques used in TLS. Learn the differences between symmetric and asymmetric encryption, how they are applied in TLS, and when each should be used. Implement practical examples of these encryption methods.

In this course, you'll extend your HTTP server into a more complete application and apply your understanding of encryption to implement TLS in HTTP. You'll learn how encryption protects data and implement security features to secure your Express.js applications.

In this course, you will learn to harden Node.js applications by preventing mixed content, enforcing HTTP Strict Transport Security (HSTS), and understanding Perfect Forward Secrecy (PFS) and TLS cipher suites. These best practices will help you secure your Express.js applications against common web threats.
