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

Dimostra controllo sui domini di un ordine di certificato OV o EV TLS/SSL

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

DigiCert attualmente supporta questi metodi DCV:

  • E-mail a contatto DNS TXT

    • Email to DNS TXT contact

    • Constructed Email

    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.

  • DNS CNAME

  • DNS TXT

  • Dimostrazione pratica HTTP (indicata anche con File o FileAuth).

  • Dimostrazione pratica HTTP (indicata anche con File o FileAuth).

Quando si ordina un certificato, selezioni un metodo DCV per dimostrare il controllo sul dominio sull’ordine. Sulla pagina Dettagli ordine del certificato, usa il metodo DCV selezionato durante il processo di ordine per completare la convalida dominio. Puoi sempre cambiare i metodi di convalida, se necessario.

To validate your domains, you can do the DCV as part of the certificate request process, or you can prevalidate your domains. Per industry standards, a domain's validation is valid for 397 days (approximately 13 months).

  • Demonstrating control over domains on DV/OV/EV TSL/SSL certificate orders

    While ordering a certificate, you select a DCV method to demonstrate control over the domains on the order. On the certificate's Order details page, use the DCV method selected during the order process to validate the domains. You can always switch validation methods if needed.

  • Domain prevalidation

    CertCentral features a domain prevalidation process that allows you to validate your domains before you begin ordering certificates for them. See Domain prevalidation: Domain control validation (DCV) methods.

    Finishing the domain validation ahead of time allows for quicker certificate issuance. For immediate certificate issuance, Domain prevalidation is required. See OV/EV certificate immediate issuance.

Metodo DCV e-mail

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 fornito 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.

See Use the Email validation method to verify domain control.

Metodo DCV E-mail a contatto DNS TXT

For this method, DigiCert sends an authorization email to the email in the DNS TXT record on the _validation-contactemail subdomain of the domain being validated. To use Email to DNS TXT contact, make sure to select the Verification email DCV method.

To configure your CertCentral Email DCV method to send the confirmation email to DNS TXT contacts, do the following:

  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 the Email validation method to verify domain control on an OV/EV TLS certificate.

Metodo DCV 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].

If we can't find an MX record for [domain_name], you another supported DCV methods to demonstrate control over the domain. See MX records (mail exchanger records).

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 addresses allows you to create a "non-expiring" email address that you can add or remove people from if necessary.

Record MX (record mail exchanger)

Prima di poter inviare correttamente un’e-mail di autenticazione (e-mail DCV) al titolare del dominio (o al controller di dominio), dobbiamo verificare che un record MX (un record risorsa nel sistema dei nomi dominio [DNS) esista nei record DNS del nome dominio del destinatario. La presenza di record MX validi ci consente di inviare l’e-mail di autenticazione.

Ad esempio, vuoi ricevere la tua e-mail DCV in uno degli indirizzi e-mail costruiti per esempio.com, admin@esempio.com. Per inviare correttamente un’e-mail DCV ad admin@esempio.com, dobbiamo prima trovare un record MX per l’indirizzo che identifica l’impostazione server (ad es. mailhost.esempio.com) per ricevere le e-mail destinate ad admin@esempio.com

Metodo DNS TXT DCV

Aggiungi un token 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 che include il token di verifica DigiCert.

Consulta Usa il metodo di convalida DNS TXT per verificare il controllo sul dominio

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.

To set up your domain's CNAME record, add the static prefix _dnsauth in the hostname field and [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.

Consulta Usa il metodo di convalida DNS CNAME per verificare il controllo sul dominio.

Metodo DCV di dimostrazione pratica HTTP (indicato anche con File o 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 addresses

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.

HTTP Practical Demonstration

Host a file containing a DigiCert generated random value (provided for the domain in your CertCentral account) at a predetermined location on your website: http://{domain-name}/.well-known/pki-validation/fileauth.txt.

Once you create the file and place it on your site, DigiCert goes to the specified URL to confirm the presence of our random value.

See Use the HTTP Practical Demonstration DCV method to verify domain control.

HTTP Practical Demonstration with unique filename

Host a file with a random filename containing a DigiCert-generated random value at a predetermined location: http://{domain-name}/.well-known/pki-validation/{unique-filename}.txt.

Once you create and place the file on your site, DigiCert goes to the specified URL to confirm the presence of our random value.

See Use the HTTP Practical Demonstration with unique filename DCV method to verify domain control.

Avvertimento

DV TLS certificates don’t support the HTTP Practical Demonstration with unique filename DCV method.
