支持用于域预验证的域控制验证 (DCV) 方法

域预验证：DCV 方法

必须在您证明对订单上的域以及任何 SAN（使用者可选名称）的控制权后，DigiCert 才能颁发 SSL/TLS 证书。我们将该流程称为域控制验证 (DCV) 流程。

DigiCert 目前支持这些 DCV 方法：

  • 发送电子邮件给 DNS TXT 联系人

    • 发送电子邮件给 DNS TXT 联系人

    • 构造的电子邮件

    警告

    End of life for the WHOIS-based Email

    On May 8, 2025, DigiCert ended support for the WHOIS-based 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?

    You must update your domain validation process to use one of the other supported DCV methods. If you still want to use the Email DCV method, use the DNS TXT record email contacts or the Constructed email method.

  • DNS CNAME

  • DNS TXT

  • HTTP 实用演示（也称为文件或 FileAuth）

  • HTTP 实用演示（也称为文件或 FileAuth）

To validate your domains, you can prevalidate your domains or complete 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. Completing 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.

    重要

    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. After placing your order, you need to complete 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

    When 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 complete the domain validation. You can always switch validation methods if needed. See Demonstrate control over domains on a pending certificate order.

电子邮件 DCV 方法

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

要证明对域的控制权，电子邮件收件人需执行为该域发送的确认邮件中的说明。确认流程包括访问所提供的链接并执行页面上的说明。

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.

“发送电子邮件给 DNS TXT 联系人”DCV 方法

For the email to DNS TXT contact DCV method, DigiCert sends an authorization email to the email addresses found in the DNS TXT record on the _validation-contactemail subdomain of the domain being validated. When 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.

    名称

    TTL

    消息

    _validation-contactemail

    默认

    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 when 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.

构造的电子邮件 DCV 方法

对于构造的电子邮件方法，DigiCert 向域的五个构造的电子邮件地址：admin、administrator、webmaster、hostmaster 和 postmaster @[domain_name]，发送一封授权邮件。

If we can't find an MX record for [domain_name], you must use one of the other supported DCV methods to demonstrate your control over the domain. See MX records (mail exchanger records) below.

Background

When 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 when necessary.

MX 记录（Mail Exchanger 记录）

在我们可以向域所有者（或域控制者）成功发送身份验证电子邮件（DCV 电子邮件）之前，我们必须确认在收件人的域名的 DNS 记录中存在 MX 记录（域名系统 [DNS] 中的资源记录）。有效 MX 记录的存在使我们可以发送身份验证邮件。

例如，您想在为 example.com 构造的其中一个电子邮件地址（例如，admin@example.com）接收 DCV 电子邮件。要将 DCV 电子邮件成功发送到 admin@example.com，我们必须首先找到识别服务器的所述地址（例如，mailhost.example.com）的 MX 记录，该服务器设置为接收目的地为 admin@example.com 的电子邮件。

DNS TXT DCV 方法

将 DigiCert 生成的令牌（为您的 CertCentral 帐户中的域提供）添加到域的 DNS 中作为 TXT 记录。当 DigiCert 搜索与域相关的 DNS TXT 记录时，我们可以找到记录，其中包括 DigiCert 验证令牌。

请参阅 添加域、授权证书的域和使用 DNS TXT 作为验证方法。

DNS CNAME DCV 方法

将 DigiCert 生成的令牌（为您的 CertCentral 帐户中的域提供）添加到域的 DNS 中作为 CNAME 记录。然后，将 dcv.digicert.com 添加为 CNAME 目标。当 DigiCert 搜索与域相关的 DNS CNAME 记录时，我们可以找到记录，其中包括 DigiCert 验证令牌。

请参阅 添加域、授权证书的域和使用 DNS CNAME 记录作为 DCV 方法。

HTTP 实用演示 DCV 方法（也称为文件或 FileAuth）

You can only use the HTTP Practical Demonstration DCV methods to demonstrate control over fully qualified domain names (FQDNs) exactly as named. To learn more, visit Domain Validation Policy Changes.

Validating IPv4 and IPv6 address

Per industry regulations, you can only 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 when validating a higher-level domain. For example, if you want to cover www.example.com, mail.example.com, and one.example.com when 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.

After you've created the file and placed it on your site, DigiCert visits the specified URL to confirm the presence of our random value. See 添加域、授权证书的域和使用 HTTP 实用演示作为验证方法.

HTTP Practical Demonstration with unique filename

Host a file with a random filename that contains 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/{unique-filename}.txt.

After you've created the file and placed it on your site, DigiCert visits the specified URL to confirm the presence of our random value. See Validate a Domain using HTTP practical demonstration with unique filename.

警告

DV TLS certificates do not support the HTTP Practical Demonstration with unique filename DCV method.
