Metodi di convalida del controllo del dominio (DCV)

Metodi DCV supportati per la convalida dei domini sugli ordini di certificato DV TLS/SSL

Prima che DigiCert possa emettere un certificato, è necessario dimostrare di avere il controllo sui domini e su eventuali SAN (nomi alternativi del soggetto) nell'ordine. Questo processo viene chiamato convalida del controllo del dominio (DCV).

I certificati DV non supportano la pre-convalida di dominio. Pertanto, ogni qualvolta ordini un certificato DV, devi dimostrare il controllo sui domini nel tuo ordine. Dopo aver effettuato l’ordine, devi completare la convalida dominio prima che DigiCert possa emettere un certificato DV.

Per i certificati in CertCentral, DigiCert attualmente supporta i seguenti metodi DCV:

  • E-mail basata su WHOIS

    • Email to DNS TXT contact

    • Constructed email

    Avvertimento

    End of life for the WHOIS-based Email

    On May 8, 2025, DigiCert ended support for the WHOIS-based domain control validation method (DCV) email method. DigiCert systems have stopped querying WHOIS entirely to find email addresses for domain validations. To learn more about this change, see our knowledge base article, End of life for WHOIS-based DCV methods.

    What should I do?

    Update your domain validation process to use one of the other supported DCV methods. To continue using the Email DCV method, use the DNS TXT record email contacts or the Constructed email method.

  • E-mail costruita

  • E-mail a contatto DNS TXT

  • DNS TXT

Convalida email

Con questo metodo di convalida, DigiCert invia tre serie di e-mail DCV: basata su WHOIS, costruita e basata su DNS TXT.

Per dimostrare il controllo sul dominio, il destinatario e-mail segue le istruzioni indicate in un’e-mail di conferma inviata per il dominio. Il processo di conferma consiste nel visitare il link nell’e-mail e seguire le istruzioni riportate sulla pagina.

Note: DigiCert sends this email from no-reply@digitalcertvalidation.com. If using allowlist, make sure to include digitalcertvalidation.com.

Convalida e-mail basata su WHOIS

With this method, DigiCert sends an authorization email to the address in the DNS TXT record on the _validation-contactemail subdomain of the domain being validating. While validating a domain, make sure to select the Verification email DCV method.

Consulta la sezione B.2.1 Contatti e-mail per record DNS TXT nell’Appendice dei requisiti base.

  1. Place the DNS TXT record on the _validation-contactemail subdomain of the domain you want to validate. The RDATA value of this text record must be a valid email address.

    Nome

    TTL

    Messaggio

    _validation-contactemail

    Impostazione predefinita

    validatedomain@digicerttest.com

    DigiCert recommends adding a distribution list rather than a personal email address. A distribution list allows you to create a "non-expiring" email address to which you can add or remove people if necessary.

  2. Update your CertCentral account settings to send the verification DCV emails to Org/Tech/Admin contacts from DNS TXT.

    1. In CertCentral, in the left menu, go to Settings > Preferences.

    2. On the Preferences page, select Advanced Settings.

    3. In the Domain Control Validation (DCV) section under Send verification DCV emails to, select Org/Tech/Admin contacts from DNS TXT.

    4. Go to the bottom of the page and select Save Settings.

  3. See our instructions for Using Email verification to validate a domain on a DV TLS certificate

Convalida e-mail costruita

Per il metodo E-mail costruita, DigiCert invia l’e-mail di autorizzazione a cinque indirizzi e-mail costruiti per il dominio: admin, amministratore, webmaster, hostmaster e postmaster @[domain_name].

Se non riusciamo a trovare un record MX per [domain_name], devi usare uno degli altri metodi DCV supportati per dimostrare il controllo sul dominio.

Background

While registering a domain, you must provide contact information, such as administrative and technical contacts. Instead of using a personal email address, you can use one of the constructed email addresses for your domain, such as webmaster@yourdomain. Using a constructed email address allows you to create a "non-expiring" email address that you can add or remove people from if necessary.

Record MX (record Mail Exchanger)

To send an authentication email to the domain controller, we must verify an MX record exists in the DNS records of the recipient's domain. The presence of valid MX records enables us to send the authentication email. An MX record is a resource record in the Domain Name System [DNS].

For example, you want us to send the DCV email to a constructed email addresses for example.com, such as admin@example.com. To email admin@example.com, we must find an MX record for the address identifying the server set up to receive emails for admin@example.com.

Convalida DNS TXT

Con questo metodo di convalida, aggiungi un valore casuale generato da DigiCert (fornito per il dominio nel tuo account CertCentral) al DNS del dominio come record TXT. Quando DigiCert effettua una ricerca per i record DNS TXT associati al dominio, possiamo trovare un record in cui il valore del record include il valore casuale DigiCert.

Metodo DNS CNAME DCV

If your domain has a CNAME record pointing to another domain (for example, yourdomain.com points to yourdomain.net), use this method to validate your domain.

With this validation method, you add the static prefix _dnsauth to DNS as a CNAME record in the hostname field. Then, add [random_value].dcv.digicert.com as the CNAME target. Once DigiCert checks for a DNS CNAME record for your domain, we can find a record that includes the DigiCert-generated random value.

Metodo DCV di dimostrazione pratica HTTP (indicato anche con File e FileAuth)

Use the HTTP Practical Demonstration DCV methods to demonstrate control over fully qualified domain names (FQDNs) exactly as named in the certificate request. To learn more, go to Domain Validation Policy Changes.

Validating IPv4 and IPv6 address

Per industry regulations, you must use the HTTP Practical Demonstration DCV method to demonstrate control over IPv4 and IPv6 addresses.

Use one of the other supported DCV methods to:

  • Validate wildcard domains, such as *.example.com.

  • Include subdomains in the validation while validating a higher-level domain. For example, if you want to cover www.example.com, mail.example.com, and one.example.com while validating the higher-level domain example.com.

  • Validate entire domains and subdomains.

Using HTTP Practical Demonstration

Con questo metodo di convalida, ospiti un file contenente un valore casuale generato da DigiCert (fornito per il dominio nel tuo account CertCentral) in una posizione predeterminata sul tuo sito web: [dominio]/.well-known/pki-validation/fileauth.txt. Una volta che il file viene creato e messo sul tuo sito, DigiCert visita l’URL specificato per confermare la presenza del nostro valore casuale.
