Validation Note: Before you can prevalidate a domain for TLS/SSL validation, you must first submit its organization for prevalidation. Additionally, if you want the domain to be used for OV, EV, and/or Private SSL certificates, you must submit its organization for those matching validation types.
Demonstrate control over your domain by hosting a .txt file containing a randomly generated token value at a predetermined location on your website. Once the file is created and placed on your site, DigiCert visits the specified URL to confirm the presence of your verification token. Make sure to avoid some of the more Common mistakes: HTTP practical demonstration DCV 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:
Under Validate This Domain For, check the validation types for which the domain must be validated.
Under Domain Control Validation (DCV) Method, select HTTP Practical Demonstration.
Note: The default DCV method is Verification Email.
When you are finished, click Submit for Validation.
Create your .txt file:
Create the .well-known/pki-validation/ directory:
Create the .well-known/pki-validation/ directory on your site and place your .txt file in it.
Note: On Windows-based servers, the .well-known folder must be created via command line (mkdir .well-known).
Verify the HTTP token
Verify the URL matches exactly, making sure that the URL for your web page matches the DigiCert provided URL.
Where YourDomain matches the domain that you are validating, and [filename].txt matches the unique hash provided by DigiCert under Your HTTP token URL (for example, c7e2ff0c848e4707594066cc860.txt).
If you are missing a period, a number, or a letter, validation cannot be completed.
