  1. Along with the WordPress website, 'Auto-Install Free SSL' works on all of the websites in your cPanel / web hosting.
  2. Option to choose Let’s Encrypt™ ACME API version (1 or 2).
  3. Issue WildCard SSL for free!
  4. If your shared hosting control panel is cPanel, this plugin automatically installs the free SSL certificates.
  5. Flexibility to set the SSL certificate renewing interval. The default interval is 30 days before the expiry.
  6. SSL certificates and private keys files are saved above the document root of your hosting (i.e., 'public_html').
  7. Option to define a directory name where the plugin stores SSL certificates and private keys files.
  8. You have the option to set SSL certificate key length.
  9. The plugin saves password/API secret in the WordPress database with the open SSL encryption.
  10. The option to create the daily cron job with a single click — no need to log in your server.
  11. In case of wildcard SSL, you get four DNS service providers for which the plugin adds DNS TXT record automatically: Cloudflare, Godaddy, Namecheap, and cPanel. If the plugin doesn't support your DNS provider, you need to add the DNS TXT record manually. At the right time, the plugin sends an email with the required data to add the DNS TXT record.
  12. After adding the DNS TXT record automatically, the plugin waits for 2 minutes. Then it sends the challenges to the Let’s Encrypt™ API to verify your domains. If your DNS service provider takes more than 2 minutes to propagate the TXT records, you have the option to make the plugin wait more than two minutes.
  13. In case of adding the DNS TXT record manually, the plugin waits until the TXT record propagation complete. If the DNS service provider takes longer to complete propagation, few web hosts may terminate the cron job. If you face such issue, please wait until the next cron job run or choose to issue non-wildcard SSL for each sub-domain.
  14. If you try to provide cPanel password or DNS API credentials over HTTP, the plugin offers the option to generate one free SSL certificate for your WordPress website. With this quick option, you need just a single click to issue the SSL certificate. So, no need to enter sensitive credentials on an insecure page.
  15. Option to revoke SSL certificate.
  16. Option to change the Let's Encrypt™ account key.

Minimum System Requirements

  1. Linux hosting
  2. WordPress 3.5
  3. PHP 5.4
  4. OpenSSL extension
  5. Curl extension
  6. PHP directive allow_url_fopen = On
  7. If your cPanel has the SSL installation feature enabled, the plugin installs SSL certificates automatically.

Case 1: This plugin needs to access cPanel API to auto-install the free SSL certificates. But if your web hosting control panel is any other than cPanel, the plugin can't install the SSL certificate automatically. In that case, you need to install the issued SSL manually.

Case 2: Do you own a cPanel hosting, but the SSL installation feature is DISABLED? Please request your web hosting provider to enable this feature. Or ask them to install the free SSL issued by this plugin.

For any of the case 1 and 2, all other processes are automated. The plugin sends an automatic email when it issues or renews free SSL. The email contains the path details of the free SSL certificate, private key, and CA bundle. You need to install the SSL yourself (case 1) or with the help of your web hosting service provider (case 2).
