域控制验证 (DCV) 方法
支持用于验证 DV TLS/SSL 证书订单上的域的 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 才能颁发证书。我们将该流程称为域控制验证 (DCV) 流程。
DV 证书不支持域预验证。因此，每次您订购 DV 证书时，都必须证明对订单上的域的控制权。下单后，您需要完成域验证，DigiCert 才能颁发您的 DV 证书。
对于 CertCentral 中的 DV 证书，DigiCert 目前支持以下 DCV 方法：
基于 WHOIS 的电子邮件
Email to DNS TXT contact
Constructed email
WHOIS-based email
构造的电子邮件
发送电子邮件给 DNS TXT 联系人
DNS TXT
电子邮件验证
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。确认流程包括访问电子邮件中提供的链接并按照页面上的说明进行操作。
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。否则，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 CA 访问您的域的 WHOIS 数据。
The industry is moving away from using WHOIS to identify domain contacts. DigiCert recommends that those using the WHOIS-based Email DCV method update their domain validation processes to use one of the other supported DCV methods as soon as possible.
If you still want to use the Email DCV method, use the DNS TXT record email 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.
“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.
请参阅基准要求附录中的 B.2.1 DNS TXT 记录电子邮件联系人。
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

消息
_validation-contactemail默认

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 Email verification to validate a domain on a DV TLS certificate
构造的电子邮件验证
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。
如果我们找不到 [domain_name] 的 MX 记录，您必须使用其他受支持的其中一种 DCV 方法证明您对域的控制权。
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 admin@example.com 的电子邮件
基于 WHOIS 的电子邮件验证
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。
Are you expecting to receive an email at an address published in your domain’s WHOIS record?
Verify that your registrar/WHOIS provider has not masked or removed that information. If the information is masked, find out if they provide a way (such as anonymized email address, web form) for you to allow Certificate Authorities (CAs) to access your domain’s WHOIS data.
DNS TXT 验证
通过此验证方法，您将 DigiCert 生成的随机值（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，其中的值包括 DigiCert 随机值。
DNS CNAME DCV 方法
通过此验证方法，您将 DigiCert 生成的随机值（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 随机值。
HTTP 实用演示 DCV 方法（也称为文件和 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.
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.
Using HTTP Practical Demonstration
通过此验证方法，您将包含 DigiCert 生成的随机值（为您的 CertCentral 帐户中的域提供）的文件托管到网站预先确定的位置：[domain]/.well-known/pki-validation/fileauth.txt。创建文件并放置到您的网站后，DigiCert 访问指定的 URL 以确认随机值的存在。
