Securing Nginx with SSL/TLS

Welcome to securing Nginx with SSL/TLS! This lesson will guide you through setting up HTTPS for your websites.

HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP. It ensures that communication between a user's browser and your Nginx server is encrypted and authenticated.

Using HTTPS is crucial for protecting sensitive data, building user trust, and is often a requirement for modern web features and SEO.

At its core, HTTPS relies on SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols. These protocols establish an encrypted link between a client and a server.

• Handshake: When you visit an HTTPS site, your browser and the server perform a 'handshake' to agree on encryption methods.
• Encryption: Once agreed, all data exchanged (passwords, credit card numbers, etc.) is encrypted, making it unreadable to eavesdroppers.
• Authentication: It also verifies the server's identity using a certificate, preventing 'man-in-the-middle' attacks.
