SSL/TLS encrypts data between a browser and server, protecting logins, payments, and user privacy. It also helps users trust your site and is required for modern browser features. Choose a certificate type that matches your domain needs, install it on your host, and confirm HTTPS works without mixed content.
How the TLS Handshake Works
When a browser connects over HTTPS, a TLS handshake establishes security. The browser verifies your certificate against a trusted Certificate Authority, both parties agree on encryption methods, and they exchange keys to encrypt all communication.
Once complete, everything between user and server, passwords, payments, personal data, travels encrypted. Anyone intercepting traffic sees scrambled data, not readable information. Without TLS, data travels in plain text where attackers can read it.
DV vs OV vs EV Certificates

DV certificates are issued in minutes. OV and EV require documentation but provide stronger trust signals for sensitive transactions.
Buying and Installing Your Certificate
Purchase from NameSilo SSL. For single domains, standard DV works. For multiple subdomains, wildcard certificates cover *.yourdomain.com. After purchase: generate a Certificate Signing Request (CSR) on your server, complete domain validation, then install the issued certificate. Most hosting panels provide guided installation. Once your SSL certificate has been installed, you can configure your site to redirect HTTP traffic to HTTPS.
HTTPS Is Mandatory for SEO
Google flags HTTP sites as "Not Secure" in Chrome. This warning damages trust and increases bounce rates. HTTPS is a confirmed ranking signal, sites without it face competitive disadvantage.
Modern browser features require HTTPS: geolocation, service workers, and progressive web apps all mandate secure connections. Running HTTP in 2026 means limited functionality and security warnings driving visitors away.
Common Mistakes: Mixed Content Errors
Mixed content occurs when HTTPS pages load resources over HTTP. Browsers block or warn about these requests, breaking functionality despite valid certificates.
Fix by updating all resource URLs to HTTPS. Check images, fonts, embedded content, and third-party scripts. Browser developer tools identify mixed content sources.
What This Means for You
NameSilo offers SSL certificates for every need, single-domain, wildcard, and multi-domain options. Manage everything from SSL Manager in your dashboard. When certificates approach expiration, note that renewal isn't technically a renewal, it's re-issuance. You receive a new certificate with fresh validity dates, requiring reinstallation. This ensures continued cryptographic security rather than extending an existing certificate.
Our certificates work with any hosting provider. Purchase through NameSilo, install anywhere, and maintain protection without vendor lock-in.
Frequently Asked Questions
What does SSL/TLS encrypt?
All data between browser and server: credentials, form submissions, payments, cookies, and page content.
Is HTTPS a ranking factor?
Yes. Google confirmed HTTPS as a ranking signal. Sites without it face disadvantages and "Not Secure" warnings.
What is a certificate authority?
A trusted organization verifying domain ownership or business identity and issuing certificates browsers recognize.
What's the difference between DV, OV, and EV?
DV verifies domain control. OV verifies business identity. EV requires rigorous verification and displays organization name.
Do I need a wildcard certificate?
Only for multiple subdomains. Wildcards cover *.domain.com; single domains need standard certificates.
How do I fix mixed content warnings?
Update all resource URLs to HTTPS. Use browser developer tools to identify HTTP resources.
How do I renew an SSL certificate?
Generate a new CSR, complete validation, install the re-issued certificate. It's a new certificate, not an extension.
What is HSTS and should I use it?
HSTS forces browsers to always use HTTPS. Enable after confirming full HTTPS functionality to prevent downgrade attacks.
