Enable SSL Certificate Now

Riley Tanaka 9 min read

Enabling an SSL certificate is a critical step for any website owner looking to secure their site, protect user data, and establish credibility online. An SSL (Secure Sockets Layer) certificate encrypts the connection between a user’s browser and your web server, safeguarding sensitive information like login credentials, payment details, and personal data. Learning how to enable SSL certificate is fundamental for modern web security. This guide will walk you through the process of how to enable SSL certificate, ensuring your website operates securely with HTTPS.

Understanding SSL Certificates and Why They Matter

Before diving into the technical steps, it’s important to understand what an SSL certificate is and its profound impact. An SSL certificate is a digital certificate that authenticates the identity of a website and encrypts information sent to the server using SSL/TLS technology. The ‘S’ in HTTPS stands for ‘secure’, indicating that the site is protected by an SSL certificate. This security is no longer optional; it’s a standard expectation for all websites.

There are several compelling reasons why you should enable SSL certificate on your website. Firstly, it protects sensitive data from being intercepted by malicious actors. Secondly, major web browsers like Chrome and Firefox now flag non-HTTPS sites as ‘Not Secure’, which can deter visitors and erode trust. Thirdly, search engines like Google favor secure websites, meaning an SSL certificate can positively impact your search engine rankings. Finally, it builds user confidence, reassuring visitors that their interactions with your site are private and secure.

Types of SSL Certificates

Understanding the different types of SSL certificates can help you choose the right one for your needs. Each type offers varying levels of validation and trust indicators.

  • Domain Validated (DV) SSL: This is the most basic and quickest to obtain. It only verifies that you own the domain name. DV SSL is suitable for blogs, personal websites, and small businesses.

  • Organization Validated (OV) SSL: This type requires more rigorous validation, checking both domain ownership and the organization’s existence. OV SSL is ideal for corporate websites and e-commerce sites.

  • Extended Validation (EV) SSL: EV SSL provides the highest level of trust, involving an extensive verification process of the organization’s identity. It often displays the organization’s name directly in the browser’s address bar, making it popular for banks and large enterprises.

  • Wildcard SSL: This certificate secures a single domain and all its subdomains (e.g., example.com, blog.example.com, shop.example.com).

  • Multi-Domain (SAN) SSL: This secures multiple distinct domain names and hostnames with a single certificate.

Acquiring Your SSL Certificate

The first step in how to enable SSL certificate is to obtain one. You can get an SSL certificate from a Certificate Authority (CA) or sometimes through your hosting provider. Many hosting providers offer free SSL certificates, often via Let’s Encrypt, or as part of their hosting packages.

Choosing an SSL Provider

You can purchase an SSL certificate from various reputable Certificate Authorities (CAs) such as Comodo, DigiCert, GlobalSign, or Symantec. Alternatively, many web hosting providers like SiteGround, Bluehost, or HostGator offer free SSL certificates, usually powered by Let’s Encrypt, which simplifies the process significantly. If your host offers a free SSL, this is often the easiest path to enable SSL certificate.

Generating a Certificate Signing Request (CSR)

To acquire an SSL certificate, you typically need to generate a Certificate Signing Request (CSR) from your web server or hosting control panel. The CSR contains information about your domain and organization, including your common name (domain name), organization name, city, state, and country. This information is used by the CA to create your unique SSL certificate. Instructions for generating a CSR vary depending on your server environment (cPanel, Plesk, Apache, Nginx, etc.).

Validating Your Domain

After submitting your CSR, the Certificate Authority needs to verify that you own or control the domain name for which you are requesting the certificate. This domain validation process can occur in a few ways:

  • Email Validation: The CA sends an email to an authorized email address associated with your domain (e.g., admin@yourdomain.com, webmaster@yourdomain.com).

  • HTTP Validation: You upload a specific file provided by the CA to a designated directory on your website.

  • DNS Validation: You add a specific CNAME or TXT record to your domain’s DNS settings.

Once validated, the CA will issue your SSL certificate files, which typically include the primary certificate, intermediate certificates (chain), and sometimes a root certificate. You will receive these files via email or through your CA’s dashboard.

Installing the SSL Certificate

Once you have your SSL certificate files, the next crucial step in how to enable SSL certificate is the installation. The installation process varies depending on your web hosting environment.

Shared Hosting (cPanel, Plesk)

For most shared hosting users, the process is straightforward via your control panel:

  1. Log in to your cPanel or Plesk account.

  2. Navigate to the ‘SSL/TLS’ section. In cPanel, it’s usually under ‘Security’.

  3. Select ‘Manage SSL sites’ or ‘Install and Manage SSL for your site (HTTPS)’.

  4. Choose your domain from the dropdown menu.

  5. Paste your certificate files: You will typically paste the ‘Certificate (CRT)’ code into one box, the ‘Private Key (KEY)’ code (which you generated with the CSR) into another, and the ‘Certificate Authority Bundle (CABUNDLE)’ or ‘Intermediate Certificate’ into a third. Some systems automatically fetch the private key and intermediate certificates if you’ve previously generated the CSR through them.

  6. Click ‘Install Certificate’.

If your hosting provider offers a ‘one-click’ SSL installation (especially for free Let’s Encrypt certificates), this step might be automated and even simpler.

VPS/Dedicated Servers (Apache, Nginx)

For users with more control over their server, you’ll need to manually configure your web server software. This involves editing configuration files.

  • Apache: You’ll typically edit your virtual host file (e.g., /etc/httpd/conf/httpd.conf or /etc/apache2/sites-available/yourdomain.conf) to include directives for SSLCertificateFile, SSLCertificateKeyFile, and SSLCertificateChainFile, pointing to the paths of your certificate, private key, and intermediate certificate files, respectively.

  • Nginx: You’ll edit your server block configuration (e.g., /etc/nginx/sites-available/yourdomain.conf) to specify ssl_certificate and ssl_certificate_key directives. You might combine your primary and intermediate certificates into a single file for Nginx.

After editing, remember to restart your web server (e.g., sudo service apache2 restart or sudo service nginx restart) to apply the changes.

Cloud Services (AWS, Google Cloud, Azure)

If you’re using cloud platforms, the process often involves specific services:

  • AWS: You’ll use AWS Certificate Manager (ACM) to provision and manage SSL certificates, which can then be integrated with services like Elastic Load Balancing (ELB) or CloudFront. If you have an external certificate, you can import it into ACM.

  • Google Cloud: Certificates are managed via the Google Cloud Console, often integrated with Load Balancing services. You can upload your certificate and private key.

  • Azure: SSL certificates are managed within Azure App Service or Azure Application Gateway settings, where you can upload your PFX file (which combines the certificate and private key).

Configuring Your Website for HTTPS

Installing the SSL certificate is only half the battle. You must also configure your website to use HTTPS exclusively. This involves several critical steps to ensure all traffic is secure and to prevent ‘mixed content’ warnings.

Updating Internal Links

All internal links within your website (links between your own pages, images, scripts, stylesheets) must be updated from http:// to https://. If your site is built on a Content Management System (CMS) like WordPress, there are plugins (e.g., Really Simple SSL) that can automate this. For static sites or custom builds, you might need to manually update links in your HTML, CSS, and JavaScript files.

Implementing 301 Redirects

It’s crucial to redirect all HTTP traffic to HTTPS. This ensures that visitors who type in http://yourdomain.com or follow old HTTP links are automatically routed to the secure version of your site. This is typically done via your web server’s configuration file:

  • Apache: Add rules to your .htaccess file (in your site’s root directory).

  • Nginx: Add redirect rules to your server block configuration.

For CMS platforms, plugins or built-in settings can often handle these redirects automatically.

Checking for Mixed Content

Mixed content occurs when an HTTPS page loads some resources (like images, scripts, or stylesheets) over an insecure HTTP connection. This can cause browsers to display security warnings, even if your SSL certificate is correctly installed. Use browser developer tools or online SSL checkers to identify and fix any mixed content issues by updating resource URLs to https://.

Verifying SSL Installation

After completing the installation and configuration, it’s essential to verify that your SSL certificate is working correctly. Open your website in a browser and look for a padlock icon in the address bar. Click on it to view certificate details. You can also use online SSL checker tools (e.g., SSL Labs’ SSL Server Test) to perform a thorough scan of your SSL configuration and identify any potential issues or vulnerabilities.

Maintaining Your SSL Certificate

SSL certificates have an expiration date, typically ranging from 90 days (for Let’s Encrypt) to one or two years. It’s vital to renew your certificate before it expires to avoid security warnings and service interruptions. Many hosting providers and CAs offer automated renewal services, especially for free certificates. If you manually installed your certificate, set reminders to renew it in advance.

Conclusion

Understanding how to enable SSL certificate and implementing it correctly is a fundamental requirement for any website in today’s digital landscape. From safeguarding sensitive data to boosting user trust and improving search engine visibility, the benefits are undeniable. By following these steps, you can successfully enable SSL certificate on your website, transforming it into a secure, reliable, and trustworthy online presence. Make sure to regularly check your certificate’s status and keep it renewed to maintain continuous security for your visitors.
