Using SSL with Cloudflare

This article discusses various options for using SSL (Secure Sockets Layer) on a Cloudflare-enabled account.

📘

Note

For information about how to activate Cloudflare for your account, please see this article. For detailed information about how to configure Cloudflare settings, please see the
Cloudflare documentation.

Using Cloudflare with an SSL certificate

To provide secure connections for your users, you must install an SSL certificate on your site. When you have an SSL certificate installed and Cloudflare enabled on your site, the entire connection is encrypted, from the browser to Cloudflare to your web server.

cPanel SSL certificates

cPanel SSL is a free, automated, and open Certificate Authority, and is recognized by most modern browsers. cPanel SSL is supported on almost every new hosting.com account, and certificates can be generated automatically for immediate use. You can use cPanel SSL certificates for the Cloudflare SSL configurations described below.

Cloudflare SSL-enabled root domains

If you have SSL enabled for your root domain (for example,example.com ), you must upgrade to Cloudflare Pro to use SSL and Cloudflare simultaneously.

Cloudflare provides two options for SSL-enabled sites:

• Full SSL: For this option, you need at least a self-signed SSL certificate. For information about how to generate and install a self-signed certificate, please see this article.

  🚧

  Important

  If you disable Cloudflare for your site, the self-signed SSL certificate is "exposed" to web visitors. They will receive warnings in their browsers that the certificate is not trusted. To prevent this scenario from occurring, you should purchase a valid SSL certificate signed by a Certificate Authority.

• Full SSL (strict): For this option, you need a valid SSL certificate signed by a Certificate Authority. This is the preferred method, because even if you disable Cloudflare for your site, it is still completely protected by the SSL certificate.

Cloudflare SSL-enabled subdomains

If you have SSL enabled for a subdomain, you can continue using the free version of Cloudflare on your root domain. However, you must make sure that the SSL-enabled subdomain is disabled (has the gray cloud iconnext to it) in your Cloudflare settings.

If you want to use Cloudflare with an SSL-enabled subdomain, you must upgrade to Cloudflare Pro.

Using Cloudflare without an SSL certificate

If your site does not currently have an SSL certificate, you can use Cloudflare Universal SSL. This feature is free, and encrypts connections between users' web browsers and Cloudflare. Connections between Cloudflare and your web site, however, are not encrypted. To secure the entire connection, you must install an SSL certificate on your server.

🚧

Important

• The Universal SSL option only works in modern browsers that support Server Name Indication (SNI). Most browsers currently in use support SNI. For information about which browsers support Cloudflare Universal SSL, please visit https://support.cloudflare.com/hc/en-us/articles/204151138-Understanding-Universal-SSL

• You should not use Universal SSL if your website processes any sensitive information, such as payment data or personally identifiable information (PII). While Universal SSL is better than nothing, to really secure your site and protect your users, you must install an SSL certificate.
