Add a domain, authorize the domain for certificates, and use HTTP practical demonstration as the validation method

In your CertCentral account, in the left main menu, go to Certificates > Domains.

On the Domains page, click New Domain.

On the New Domain page, under Domain Details, enter the following domain information:

• Domain Name
  Enter the domain name the certificates will secure.
• Organization
  In the dropdown, select the organization you want to assign the domain to.

Under Validate This Domain For, check the validation types for which the domain must be validated.

• OV/EV Domain Validation
  Allows you to order OV and EV SSL/TLS certificates for this domain, such as Standard SSL, Secure Site SSL, and Secure Site Pro EV SSL.
• Private SSL Domain Validation
  Allows you to order private SSL certificates for this domain, such as Private SSL and Private Multi-Domain SSL.

Under Domain Control Validation (DCV) Method, select HTTP Practical Demonstration.

When you are finished, click Submit for Validation.

Create your .txt file:

1. Under User Actions, in the Your unique verification token box, copy your verification token.
   Note: The unique verification token expires after thirty days. To generate a new token, click the Generate New Token link.
2. Open a text editor (such as Notepad) and paste in Your unique verification token.
3. Save the .txt file under this name: fileauth.txt.

Create the .well-known/pki-validation/ directory on your site.

Place the fileauth.txt file on your site under .well-known/pki-validation.

The URL should look something like this:

http://[yourdomain]/.well-known/pki-validation/fileauth.txt
