Setting up cPanel SSL and Cloudflare Universal SSL for end-to-end encryption

Cloudflare offers SSL for all sites, but Cloudflare SSL only encrypts the connection from the visitor to Cloudflare. This article shows how to provide full, end-to-end encryption for the entire connection from the visitor to the server.

Step 1: Set up the domain

In order to complete the setup process correctly, cPanel SSL requires the domain to resolve to the server IP address. If the domain does not resolve to the server IP address, update the domain name servers to the designated A2 Hosting name servers for your account. For more information about how to set name servers, please see this article.

Step 2: Verify the cPanel SSL certificate has been issued

To verify the cPanel SSL certificate has been issued for the domain, follow these steps:

1. Log in to cPanel.
   If you do not know how to log in to your cPanel account, please see this article.
2. In the SECURITY section of the cPanel home screen, click the SSL/TLS Status icon:

   

3. On the SSL/TLS Status page, locate the domain in the Domain column.

4. To the right of the domain is a green lock symbol with the label AutoSSL Domain Validated. If the lock symbol is not green or does not appear, the certificate is not installed.
   

   

   Alternatively, you can use an external validation tool like https://www.sslshopper.com/ssl-checker.html to check the SSL certificate.

Step 3: Configure Cloudflare

To sign up and configure Cloudflare for your domain, follow these steps:

1. Go to https://www.cloudflare.com, and then click Sign Up. A new page appears:

   

   • In the Email text box, type an e-mail address.
   • In the Password text box, type a password.
   • Click Create Account to continue.
   If you already have a Cloudflare account, you do not need to follow this step. Log in to Cloudflare with your existing account instead.
2. The Welcome to Cloudflare page appears. At the top of the page, click Add site.

3. On the next page, in the Enter your site text box, type your domain name, and then click Add site:
   

   

4. On the next page, select a plan, and then click Continue. Cloudflare scans the domain's DNS records.
   

   If you are unsure which plan to use, start with the Free plan.
5. DNS analysis results appear on the next page. Review the information and correct any errors. When you are done, click Continue.
6. The next page displays the nameservers to use for your domain. Make a note of the nameservers, and then click Done, check nameservers.

7. The Overview page appears. Click the SSL/TLS icon, and then click the Full or Full (strict) radio button on the SSL/TLS page:
   

   

   • Full (strict) mode requires that the domain have a valid certificate issued by a recognized certificate authority (CA), such as DigiCert.
   • If you use Full (strict) mode, you may need to temporarily disable it (for example, by enabling Full mode) when renewing a cPanel SSL certificate. Doing this ensures that the domain verification procedure runs correctly.

Step 4: Update name servers and verify

To update the name servers and verify the configuration, follow these steps:

1. Use the control panel at the domain’s registrar to change the name servers to those provided by Cloudflare.
2. After 24 hours, verify the changes. The domain should resolve to Cloudflare IP addresses and the SSL certificate should be the Cloudflare Universal SSL certificate (sni.cloudflaressl.com).

More Information

Using cPanel SSL with Cloudflare SSL is a great way to add security to a site quickly and at no cost. However, it may be more convenient to use a traditional CA-issued certificate.
