How to Generate a Free SSL Certificate & Enable HTTPS

Securing your website with HTTPS is one of the easiest ways to boost trust, protect your users, and improve your Google ranking — all at no cost. Modern browsers now flag unencrypted sites as “Not Secure,” and without SSL, your site becomes vulnerable to interception or data leaks.

The good news? You can get a valid SSL certificate completely free using tools like GetHTTPSforFree.com, which connects directly to Let’s Encrypt — the open certificate authority trusted by millions of websites across the internet.

This guide will show you how to generate and install your SSL certificate for free, plus compare other reliable free SSL providers you can explore in 2025.


What Is an SSL Certificate and Why It Matters

An SSL certificate (Secure Sockets Layer) encrypts the data between your visitors and your web server, ensuring no one can intercept or modify information in transit. When you see the padlock icon beside your URL, that means your website is using HTTPS — the secure version of the web.

Here’s why HTTPS is essential:

  • Data Protection: Encrypts sensitive information like passwords and payment details.
  • SEO Boost: Google ranks HTTPS websites higher than HTTP ones (Google Search Central).
  • Trust & Credibility: Users instantly trust sites showing the secure padlock.
  • Browser Compliance: Modern browsers block key features (like geolocation and notifications) on non-HTTPS sites.

Why Use GetHTTPSforFree

GetHTTPSforFree.com is a lightweight web interface that uses Let’s Encrypt to help you issue free SSL certificates manually. It’s a great choice if your hosting service doesn’t support built-in SSL management or if you prefer full control over your certificate files.

Key advantages:

  • 100% free — no hidden costs.
  • Transparent, open-source process (GitHub repo).
  • Works for any domain, even custom setups.
  • Ideal for developers or advanced users comfortable using command-line tools like OpenSSL.

How to Generate a Free SSL Certificate (Step-by-Step)

Step 1: Visit GetHTTPSforFree.com

Go to GetHTTPSforFree.com. You’ll be guided through four main steps:

  1. Register an account key.
  2. Verify your domain.
  3. Sign the required requests.
  4. Download your SSL certificate.

Make sure you have OpenSSL installed — you’ll need it to run the signing commands displayed on the website.


Step 2: Generate Your Keys and CSR

Before starting, you’ll generate two files:

  • A private key (keep this secret at all costs).
  • A CSR (Certificate Signing Request), which includes your domain and public key.

Run the following commands in your terminal:

openssl genrsa 2048 > account.key
openssl req -new -sha256 -key account.key -subj "/CN=yourdomain.com" > domain.csr

⚠️ Never share your private key (account.key). Only your CSR and public keys are needed during verification.


Step 3: Verify Domain Ownership

Let’s Encrypt needs to confirm you own the domain. You can verify ownership using one of these methods:

  • HTTP Challenge: Upload a unique file (provided by GetHTTPSforFree) to: http://yourdomain.com/.well-known/acme-challenge/
  • DNS Challenge: Add a TXT record to your domain’s DNS configuration as instructed.

Once the verification file or record is detected, your certificate is issued automatically through Let’s Encrypt’s API.

Step 4: Download and Install Your Certificate

After verification, download your issued files:

  • cert.pem – the SSL certificate.
  • chain.pem – intermediate certificate (CA).
  • privkey.pem – your private key.

You’ll now configure your web server. For Nginx, it looks like this:

server {
  listen 443 ssl;
  server_name yourdomain.com www.yourdomain.com;

  ssl_certificate     /etc/ssl/yourdomain/fullchain.pem;
  ssl_certificate_key /etc/ssl/yourdomain/privkey.pem;

  location / {
    root /var/www/html;
    index index.html;
  }
}

To ensure all traffic uses HTTPS, add this redirect block:

server {
  listen 80;
  server_name yourdomain.com www.yourdomain.com;
  return 301 https://$host$request_uri;
}

Restart Nginx, then open https://yourdomain.com — you should now see a secure padlock in your browser.


Step 5: Renewal and Maintenance

Let’s Encrypt certificates are valid for 90 days. You can renew them manually by repeating the same process or automate renewal using tools like:

Automation is strongly recommended to avoid downtime due to expired certificates.
