SSL encrypts communication between a visitor’s browser and a website. That protection matters whenever people enter passwords, personal details, or payment information, and it helps prevent the alarming “Not Secure” browser warning. section 10.5 section 10.9
For a website owner, the practical goal is simple: use HTTPS rather than HTTP. HTTPS signals that encrypted protection is active, giving customers more confidence before sharing information or buying something. section 10.5
Why encrypted site communication is essential:
- Protects transmitted personal information, login credentials, and financial transaction data from being read if intercepted. section 10.5
- Avoids a “Not Secure” warning that can cause visitors to leave immediately. section 10.5 section 11.6
- Supports e-commerce by making customers more willing to provide credit-card or other personal information. section 10.5
A checkout-ready site
A visitor lands on an online store and sees HTTPS instead of a “Not Secure” warning. The site can then protect the information exchanged as the visitor signs in, enters an address, and pays. section 10.5
Although “SSL” remains the common label, Transport Layer Security (TLS) has replaced it in practice. TLS 1.3 is identified as a newer version with stronger cryptographic algorithms and a streamlined handshake for faster, more secure connections. section 10.5
Many hosting services include free SSL and automatically install and verify it through hosting utilities such as cPanel or Site Tools. Self-hosting requires a more complex multistep installation, so confirm that SSL is included when choosing a host. section 2.2 section 10.5
