Utiliser la méthode de validation par DNS CNAME pour vérifier le contrôle du domaine

Prouver que vous contrôlez votre domaine grâce à un enregistrement DNS CNAME

Use these instructions to validate a domain using the DNS CNAME DCV method. In the domains DNS as a CNAME record, add _dnsauth in the hostname field. Then, add [random_value].dcv.digicert.com to the target host field, to point the random value and domain to DigiCert at dcv.digicert.com.

Vérifiez l’état de votre commande de certificat TLS/SSL et utiliser la méthode DCV par enregistrement DNS CNAME pour prouver que vous contrôlez les domaines cités dans la commande. Pour obtenir davantage d'informations, consultez la page Prouver le contrôle des domaines de votre commande de certificat SSL.

Before you begin

For faster certificate issuance, validate domains before ordering your OV and EV TLS certificates. Learn more about domain prevalidation.

Étape 1 : vérifier le statut de votre commande en attente

  1. Dans votre compte CertCentral, accédez à la page des détails de la commande Order # (N° de commande).

    1. In the left main menu, go to Certificates > Orders.

    2. On the Orders page, in the Order # column, select the certificate's order number link.

    3. For CertCentral Subscription accounts, the steps to access the Order # detail page are different.

      1. In the left menu, go to My Digital Trust Products > Certificates.

      2. On the Certificates page, in the Order # column, select the certificate's order number link.

  2. Sur la page de détails Order # (N° de commande), dans la section Order Status (État de la commande), vérifiez l’état d'émission de la commande (la commande est-elle en attente de validation du domaine ou de l’organisation pour pouvoir être finalisée ?).

    When validation is done the Certificate status section no longer appears on the Order # details page.

  3. Under What do you need to do, select the domain's link you want to validate.

  4. In the Prove control over domain window, in the Domain control validation (DCV) method menu, select DNS CNAME Record and then select Save.

  5. Under 2. Add the DigiCert provided token to your CNAME record, in the Order token box, copy the DigiCert-provided random value.

    The random value expires in 30 days.

  6. Create your DNS CNAME record.

    1. Go to your DNS provider’s site and create a new CNAME record.

      For more detailed instructions for creating or updating a DNS CNAME record, try the following resources:

      • Your DNS provider's documentation.

      • DigiCert knowledge base for articles like this one: Create a CNAME Record.

    2. In the hostname field (or equivalent), enter _dnsauth.

    3. In the record type field (or equivalent), select CNAME.

    4. In the target host field (or equivalent), enter [random_value].dcv.digicert.com to point the CNAME record to dcv.digicert.com.

    5. Select a Time-to-Live (TTL) value or use your DNS provider's default value.

    6. Save the record.

    Important

    On October 28, 2025, DigiCert ended support for the [random_value] prefix DNS CNAME record configuration. To learn more about this change, see the October 28 change log entry.

  7. Complete domain validation.

    1. In CertCentral, go to the certificate's Order # details page.

      1. In the left menu, go to Certificate > Orders.

      2. On the Orders page, in the Order # column, select the certificate's order number link.

      For CertCentral Subscription accounts:

      1. In the left menu, go to My Digital Trust Products > Certificates.

      2. On the Certificates page, in the Order # column, select the certificate's order number link.
