SSL Certificates Guide
Welcome to your Digital Certificate Handbook. An SSL (Secure Sockets Layer) certificate creates an encrypted tunnel between your web server and your visitors’ browsers. This ensures that sensitive data—like passwords and credit card numbers—remains private and that your website is authenticated as genuine.
Today, security is mandatory. Modern browsers display “Not Secure” warnings for sites without encryption, and search engines prioritize secure sites in their rankings. This guide serves as your central hub for the entire SSL lifecycle:
- Getting Started: Learn the basics of What an SSL Certificate Is and how to Order a Standard or Premium SSL.
- Setup: Before installation, you must Generate a CSR and Verify Ownership of your domain.
- Installation: We provide step-by-step guides to install certificates on Linux Command Line, WHM / cPanel, Plesk, or InterWorx (SiteWorx).
- Maintenance: Keep your site secure by learning how to Renew your SSL or Troubleshoot Common Errors like “Connection Not Private.”
