Validate a domain using HTTP Practical Demonstration with unique filename

Add a domain and validate it using HTTP Practical Demonstration with unique filename domain control validation (DCV) method

When done creating the file and placing it on your site, DigiCert goes to the specified URL to confirm the presence of our random value. Make sure to avoid the common mistakes when using the HTTP practical demonstration DCV methods.

Importante

Use the HTTP Practical Demonstration DCV methods to demonstrate control over a fully qualified domain name (FQDN) exactly as named. To learn more, go to Domain Validation Policy Changes.

Use another supported DCV method, such as email, DNS TXT, and CNAME, to prevalidate entire domains and subdomains.

Acronyms in this article: Domain Name System (DNS), extended validation (EV), organization validation (OV) Transport Security Layer (TLS)

Before you begin

When you add a domain to your account, you must assign the domain to an organization in your account. However, before assigning a domain to it, you must first add the organization to your account. See Add an organization to your CertCentral account.

Also. if you want the domain used for OV, EV, or Private TLS certificates, submit its organization for prevalidation and include those matching validation types. See Submit an organization for pre-validation.

Step 1: Add a domain and select HTTP Practical Demonstration with unique filename as the DCV method

  1. In CertCentral, in the left menu, go to the Certificates > Domains.

    For CertCentral Subscription accounts, in the left menu, go to Validation > Domains.

  2. On the Domains page, select New domain.

  3. On the new Domains page, under Domain details enter the following information:

    1. Domain name

      Enter the domain you want to prevalidate.

    2. Organization

      In the dropdown, select the organization you want to assign the domain to.

  4. Under Domain control validation (DCV) method, select HTTP Practical Demonstration with unique filename.

  5. When ready, select Submit for validation.

Step 2: Use HTTP Practical Demonstration with unique filename to demonstrate control over the domain

  1. On the domain's details page, in the Domain control validation (DCV) method section under User actions, do the following:

    1. Create a .txt file and add the DigiCert-provided random value.

      1. Open a text editor (for example, Notepad).

      2. In the Your unique verification token box, copy your token and enter the random value in text editor.

        The random value expires after 30 days.

      3. Save the .txt file under the DigiCert-provided random filename (for example, ES3e9203kd0238K3.txt).

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

      For Windows-based servers, create the .well-known folder via command line (mkdir .well-known).

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

    The URL should look something like this:

    http://[your-domain]/.well-known/pki-validation/ES3e9203kd0238K3.txt

  3. Finish domain validation.

    1. In CertCentral, in the left menu, go to Certificates > Domains.

      For CertCentral Subscription accounts, in the left menu, go to Validation > Domains.

    2. On the Domains page, in the Domain name column, select the domain link.

    3. On the domain's details page, in the Domain control validation (DCV) method section under User actions select Check HTTP Token.
