適用於網域驗證的支援的網域控制驗證 (DCV) 方法

網域預先驗證：DCV 方法

DigiCert 發行 SSL/TLS 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。

DigiCert 目前支援這些 DCV 方法：

  • 以電子郵件傳送給 DNS TXT 聯絡人

    • 以電子郵件傳送給 DNS TXT 聯絡人

    • 建構的電郵

    • WHOIS-based Email

  • DNS CNAME

  • DNS TXT

  • HTTP Practical Demonstration (HTTP 現實論證) 也稱為檔案或檔案驗證

  • HTTP Practical Demonstration (HTTP 現實論證) 也稱為檔案或檔案驗證

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.

    Important

    DV certificates don't support domain prevalidation. Therefore, each time you order a DV 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 .

  • 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.

電郵 DCV 方法

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。確認程序由瀏覽提供的連結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.

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

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。如果他們已遭到遮蔽，瞭解他們是否提供方式 (例如匿名的電郵地址、Web 表格)，讓您允許憑證授權單位 (CA) 存取您網域的 WHOIS 資料。

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 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.

  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.

建構的電郵 DCV 方法

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]。

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 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) 設定以接收目的地為 admin@example.com 的電郵

基於 WHOIS 的電郵 DCV 方法

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 DCV 方法

將 DigiCert 產生的權杖 (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，我們可以找到包括 DigiCert 驗證權杖所在的記錄。

請參閱 新增網域，授權用於憑證的網域，然後使用 DNS TXT 作為驗證方法。

DNS CNAME DCV 方法

將 DigiCert 產生的權杖 (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 驗證權杖所在的記錄。

請參閱 新增網域，授權用於憑證的網域，然後使用 DNS CNAME 記錄作為 DCV 方法。

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. 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 新增網域，授權用於憑證的網域，然後使用 HTTP 現實論證作為驗證方法.

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 Add a domain and validate it using HTTP practical demonstration with unique filename as the validation method.

Warning

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