SSL Certificates
- What is an SSL certificate and why do I need one?
An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. You need one to secure data transfer, protect user privacy, and avoid browser warnings that can deter visitors. - How do I get a free SSL certificate for my domain?
You can get a free SSL certificate from Let's Encrypt, a nonprofit certificate authority. Many web hosts and control panels offer one-click installation of Let's Encrypt certificates, or you can use tools like Certbot to obtain and renew them automatically. - What is the difference between HTTP and HTTPS?
HTTP is the unencrypted protocol for transferring web pages, while HTTPS is the secure version that encrypts data using SSL/TLS. HTTPS protects data from eavesdropping and tampering, and is now the standard for all websites. - Why is my SSL certificate not working?
Your SSL certificate might not work due to an expired certificate, incorrect installation, domain name mismatch, or a misconfigured server. Check the certificate details and server settings to diagnose the issue. - How do I force HTTPS on my website?
Force HTTPS by redirecting all HTTP traffic to HTTPS using server-side rules (e.g., .htaccess or Nginx config) or a CDN setting. Also update internal links and use HSTS for added security. - What is a wildcard SSL certificate?
A wildcard SSL certificate secures a primary domain and all its subdomains (e.g., *.example.com) with a single certificate. It's ideal for sites with many subdomains but doesn't cover multiple root domains.
