Metodi di convalida del controllo del dominio (DCV) supportati per la pre-convalida dominio

Pre-convalida dominio: Metodi DCV

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. Questo processo viene chiamato convalida del controllo del dominio (DCV).

DigiCert attualmente supporta questi metodi DCV:

  • E-mail a contatto DNS TXT

    • E-mail a contatto DNS TXT

    • E-mail costruita

    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 (indicato anche con File o FileAuth)

  • Dimostrazione pratica HTTP (indicato anche con File o FileAuth)

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

  • Domain prevalidation

    CertCentral features a domain prevalidation process that allows you to validate your domains before you begin ordering certificates for them. Validating the domain ahead of time allows for quicker certificate issuance.

    For immediate certificate issuance, Domain prevalidation is required. See OV/EV certificate immediate issuance.

    DV TLS certificates don't support domain prevalidation

    Each time you order a DV TLS certificate, you must demonstrate control over the domains on the order. Once you submit the order, you need to finish the domain validation before DigiCert can issue your DV certificate. See Supported DCV methods for validating the domains on DV TLS/SSL certificate orders.

  • 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 your domains. You can always switch validation methods if needed. See Demonstrate control over domains on a pending certificate order.

Metodo DCV e-mail

With this validation method, DigiCert sends two sets of DCV emails: DNS TXT-based and constructed.

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 Add a domain and validate it using the Email DCV method.

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. While validating a domain, 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 Adding a domain and validate it using the Email DCV method.

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 must use another supported DCV methods to demonstrate your 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 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)

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 tale 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 Aggiungi un dominio, autorizza il dominio per i certificati e usa DNS TXT come metodo di convalida.

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 to 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 Aggiungi un dominio, autorizza il dominio per i certificati e usa il record DNS CNAME come metodo DCV.

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. 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.

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 Aggiungi un dominio, autorizza il dominio per i certificati e usa la dimostrazione pratica HTTP come metodo di convalida.

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 the file and place it on your site, DigiCert goes to the specified URL to confirm the presence of our random value. See Validate a Domain using HTTP practical demonstration with unique filename.

Avvertimento

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