網域控制驗證 (DCV) 方法
使用於 DV TLS/SSL 憑證訂單上驗證網域的支援的 DCV 方法
DigiCert 發行憑證前,您必須證明您對訂單上的網域及任何 SAN (主體別名) 擁有控制權。我們參考作為「網域控制驗證 (DCV)」程序的此程序。
DV 憑證不支援網域預先驗證。因此,每次您訂購 DV 憑證時,您必須證明您對訂單上的網域擁有控制權。在您下訂單後,您需要在 DigiCert 可以發行您的 DV 憑證前完成網域驗證。
對於 CertCentral 中的 DV 憑證,DigiCert 目前支援以下的 DCV 方法:
基於 WHOIS 的電郵
Email to DNS TXT contact
Constructed email
WHOIS-based email
建構的電郵
以電子郵件傳送給 DNS TXT 聯絡人
DNS TXT
電郵驗證
DigiCert 使用此驗證法可以傳送三組 DCV 電郵:基於 WHOIS、建構的和基於 DNS TXT。
若要證明對網域擁有控制權,電郵收件者遵照傳送給網域的確認電郵中的指示。確認程序由瀏覽電郵中的連線和遵照頁面上的指示所組成。
Note: DigiCert sends this email from no-reply@digitalcertvalidation.com. If using allowlist, make sure to include digitalcertvalidation.com.
Important
您是否正期待在您的網域的 WHOIS 記錄中發佈的位址收到電郵?請確認您的註冊機構/WHOIS 提供者未遮罩或移除該資訊。如果他們有,瞭解他們是否提供方式 (例如匿名的電郵地址、Web 表格),讓您允許 CA 存取您網域的 WHOIS 資料。
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.
以電子郵件傳送給 DNS TXT 聯絡人 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.
請參閱基準要求的附錄中的「第 B.2.1 節 - DNS TXT 記錄電郵聯絡人」。
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.名稱
TTL
訊息
_validation-contactemail
預設
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 Email verification to validate a domain on a DV TLS certificate
建構的電郵驗證
關於「建構的電郵」方法,DigiCert 將授權電郵傳送給網域的五個建構的電郵地址:admin、administrator、webmaster、hostmaster 和 postmaster @[domain_name]。
如果我們找不到 [domain_name] 的 MX 記錄,您必須使用其中一個其他支援的 DCV 方法,證明有網域的控制權。
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 記錄 (郵件交換程式記錄)
在我們可以成功傳送驗證電郵 (DCV 電郵) 給網域擁有者 (或網域控制者) 前,我們必須驗證 MX 記錄 (在網域名稱系統 [DMS] 中的來源記錄) 存在收件者的網域名稱的 DNS 記錄中。存在有效的 MX 記錄讓我們可以傳送身份驗證電郵。
例如,您想要在 example.com、admin@example.com 其中一個建構的電郵地址收到您的 DCV 電郵。若要成功傳送 DCV 電郵給 admin@example.com,我們必須先找到該位址的 MX 記錄,識別伺服器 (例如 mailhost.example.com) 設定以接收 admin@example.com 的電郵
基於 WHOIS 的電郵驗證
關於基於 WHOIS 的方法,DigiCert 傳送電郵給如網域的 WHOIS 記錄中所示的公用網域的註冊擁有者。
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 驗證
使用此驗證法,您可以將 DigiCert 產生的隨機值 (提供給您的 CertCentral 帳戶中的網域) 新增到網域的 DNS 中作為 TXT 記錄。當 DigiCert 搜尋與網域關聯的 DNS TXT 記錄時,我們可以找到記錄的值包括 DigiCert 隨機值所在的記錄。
DNS CNAME DCV 方法
使用此驗證法,您可以將 DigiCert 產生的隨機值 (提供給您的 CertCentral 帳戶中的網域) 新增到網域的 DNS 中作為 CNAME 記錄。然後新增 dcv.digicert.com 作為 CNAME 目標。當 DigiCert 搜尋與網域關聯的 DNS CNAME 記錄時,我們可以找到包括 DigiCert 隨機值的記錄。
HTTP Practical Demonstration DCV (HTTP 現實論證 DCV) 方法 (也稱為檔案或檔案驗證)
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
使用此驗證法,您可以在您的網站的預定位置,託管有 DigiCert 產生的隨機值 (提供給您的 CertCentral 帳戶中的網域) 的檔案:[domain]/.well-known/pki-validation/fileauth.txt。一建立檔案並放置在您的網站時,DigiCert 會瀏覽指定的 URL 以確認是否有我們的隨機值。
