2. Find SSL/Security section
3. Enable Let’s Encrypt or AutoSSL
4. SSL activates within minutes ### Cloudflare SSL 1. Add site to Cloudflare
5. Update nameservers
6. SSL section → Choose mode
7. Certificate issues automatically ### Manual Installation (Certbot) ```bash

Install certbot

sudo apt install certbot python3-certbot-nginx # Get certificate sudo certbot —nginx -d example.com -d www.example.com # Auto-renewal test sudo certbot renew —dry-run

2. Submit CSR to certificate provider
3. Complete validation (DV/OV/EV process)
4. Download certificate files
5. Install on server (varies by server type)
6. Configure redirects (HTTP to HTTPS) ## Common Issues ### Mixed Content **Problem:** Page loads over HTTPS but includes HTTP resources. **Solution:** Update all resource URLs to HTTPS or use protocol-relative URLs. ### Certificate Not Trusted **Causes:**
- Missing intermediate certificates
- Self-signed certificate
- Expired certificate
- Wrong domain **Solution:** Install complete certificate chain, check expiration, verify domain. ### Redirect Loops **Problem:** Infinite redirect between HTTP and HTTPS. **Solution:** Check server configuration, Cloudflare settings, and .htaccess rules. ## FAQ ### Is Let's Encrypt secure enough? Yes. Let's Encrypt uses the same encryption strength as paid certificates. The encryption itself is identical—the differences are in validation level, warranty, and support. ### Why do some certificates cost $500+ when others are free? You're paying for:
- Extended or Organization Validation
- Warranty/insurance
- Priority support
- Site seals and trust indicators
- Longer validity periods ### Do I need EV for e-commerce? Not necessarily. Modern browsers no longer show the green bar for EV. If you're using a payment processor (Stripe, PayPal), their certificates handle payment pages. Standard DV is fine for most e-commerce. ### How often do certificates renew? - Let's Encrypt: Every 90 days (automated)
- Paid certificates: 1 year typical, some offer multi-year ### What happens if my certificate expires? Browsers will show a security warning. Visitors see a full-page warning and most will leave. Set up automated renewal or calendar reminders. ### Can I use the same certificate on multiple servers? Yes, you can install the same certificate on multiple servers. Wildcard certificates are especially useful for this. ## Conclusion For most websites, **Let's Encrypt** (free) provides all the security you need. It's automated, trusted, and offers the same encryption as paid alternatives. **Consider paid certificates when:**
- You need OV/EV validation for compliance
- Warranty requirements exist
- Premium support is valuable to you
- Specific compliance standards require it **Our recommendations:** | Scenario | Recommendation |
