支持用于验证 OV/EV TLS/SSL 证书订单上的域的 DCV 方法
证明对待处理 OV 或 EV TLS/SSL 证书订单上所列域的控制权
必须在您证明对证书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
Email to DNS TXT contact
Constructed Email
WHOIS-based Email
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）。
在订购证书时，选择要证明对订单上所列域的控制权的 DCV 方法。在证书的订单详细信息页面，使用在订购流程中选择的 DCV 方法完成域验证。如有需要，您可以随时更改验证方法。
To validate your domains, you can complete 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
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.
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.
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.
电子邮件 DCV 方法
使用该验证方法，DigiCert 发送两组 DCV 电子邮件：基于 WHOIS 的电子邮件、构造的电子邮件和基于 DNS TXT 的电子邮件。
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.
重要
您是否希望在您的域的 WHOIS 记录中发布的地址接收电子邮件？
请验证您的注册机构/WHOIS 提供者未遮掩或删除该信息。如果该信息被遮掩，请查实他们是否提供一种方法（例如，匿名处理的电子邮件地址、Web 表单）可用于允许证书颁发机构 (CA) 访问您的域的 WHOIS 数据。
If you still want to use the Email DCV method, use the Email to DNS TXT contact or the Constructed email method.
To learn more about the end of life for WHOIS-based email, see our knowledge base article, End of Life for WHOIS based email DCV method.
See Use the Email validation method to verify domain control.
“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 you are validating. 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:
Place the DNS TXT record on the
_validation-contactemailsubdomain 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.
Update your CertCentral account settings to send the verification DCV emails to Org/Tech/Admin contacts from DNS TXT.
In CertCentral, in the left menu, go to Settings > Preferences.
On the Preferences page, select Advanced Settings.
In the Domain Control Validation (DCV) section under Send verification DCV emails to, select Org/Tech/Admin contacts from DNS TXT.
Go to the bottom of the page and select Save Settings.
See our instructions for Using the Email validation method to verify domain control on an OV/EV TLS certificate.
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 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 addresses 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
基于 WHOIS 的电子邮件 DCV 方法
For the WHOIS-based method, DigiCert sends an authorization email to the registered owners of the public domain as shown in the domain's WHOIS record.
对于基于 WHOIS 的方法，DigiCert 向域的 WHOIS 记录中显示的注册的公共域持有人发送一封授权邮件。
DNS TXT 记录电子邮件联系人
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。
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。
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 in the certificate request. To learn more, visit Domain Validation Policy Changes.
Use one of the other supported DCV methods, such as email, DNS TXT, and CNAME, 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 Use the HTTP Practical Demonstration DCV method to verify domain control.
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 Use the HTTP Practical Demonstration with unique filename DCV method to verify domain control.
警告
DV TLS certificates do not support the HTTP Practical Demonstration with unique filename DCV method.
