CertCentral: DNS CNAME DCV method now available for DV certificate orders

In CertCentral and the CertCentral Services API, you can now use the DNS CNAME domain control validation (DCV) method to validate the domains on your DV certificate order.

Note: Before, you could only use the DNS CNAME DCV method to validate the domains on OV and EV certificate orders and when prevalidating domains.

To use the DNS CNAME DCV method on your DV certificate order:

  • In CertCentral:
    • When ordering a DV TLS certificate, you can select DNS CNAME as the DCV method.
    • On the DV TLS certificate's order details page, you can change the DCV method to DNS CNAME Record.
  • In the Services API:
    • When requesting a DV TLS certificate, set the value of the dcv_method request parameter to dns‑cname‑token.

Note: The AuthKey process for generating request tokens for immediate DV certificate issuance does not support the DNS CNAME DCV method. However, you can use the File Auth (http‑token) and DNS TXT (dns‑txt‑token) DCV methods. To learn more, visit DV certificate immediate issuance.

CertCentral Services API: Improved List domains endpoint response

To make it easier to find information about the domain control validation (DCV) status for domains in your CertCentral account, we added these response parameters to domain objects in the List domains API response:

  • dcv_approval_datetime: Completion date and time of the most recent DCV check for the domain.
  • last_submitted_datetime: Date and time the domain was last submitted for validation.

For more information, see the reference documentation for the List domains endpoint.


Industry changes to file-based DCV (HTTP Practical Demonstration, file auth, file, HTTP token, and HTTP auth)

To comply with new industry standards for the file-based domain control validation (DCV) method, you can only use the file-based DCV to demonstrate control over fully qualified domain names (FQDNs), exactly as named.

To learn more about the industry change, see Domain validation policy changes in 2021.

How does this affect me?

As of November 16, 2021, you must use one of the other supported DCV methods, such as Email, DNS TXT, and CNAME, to:

  • Validate wildcard domains (*
  • To include subdomains in the domain validation when validating the higher-level domain. For example, if you want to cover, when you validate the higher-level domain,
  • Prevalidate entire domains and subdomains.

CertCentral: Pending certificate requests and domain prevalidation using file-based DCV

Pending certificate request

If you have a pending certificate request with incomplete file-based DCV checks, you may need to switch DCV methods* or use the file-based DCV method to demonstrate control over every fully qualified domain name, exactly as named, on the request.

*Note: For certificate requests with incomplete file-based DCV checks for wildcard domains, you must use a different DCV method.

To learn more about the supported DCV methods for DV, OV, and EV certificate requests:

Domain prevalidation

If you plan to use the file-based DCV method to prevalidate an entire domain or entire subdomain, you must use a different DCV method.

To learn more about the supported DCV methods for domain prevalidation, see Supported domain control validation (DCV) methods for domain prevalidation.


CertCentral Services API

If you use the CertCentral Services API to order certificates or submit domains for prevalidation using file-based DCV (http-token), this change may affect your API integrations. To learn more, visit File-based domain control validation (http-token).


CertCentral Services API: Domain management enhancements

To make it easier to maintain active validation for domains in your account, we added new filters, response fields, and a new endpoint to our domain management APIs. With these updates, you can:

  • Find domains with OV and EV validation reuse periods that are expired or expiring soon.
  • Find domains affected by the September 27, 2021 policy change to shorten OV domain validation reuse periods.*

Enhanced APIs: List domains and List subaccount domains

We made the following enhancements to the List domains and List subaccount domains endpoints:

  • Added validation filter values
    On September 27, 2021*, existing OV domain validation reuse periods will shorten to 397 days from the date validation was completed. For some domains, the reduced validation period will have already expired, or will expire before the end of 2021.

    To help you find these domains so you can resubmit them for validation, we added a new value for the validation filter: shortened_by_industry_changes. We also added filter values to help you find domains with OV or EV domain validation periods that expire in different timeframes. The new validation filter values include:
    • shortened_by_industry_changes
    • ov_expired_in_last_7_days
    • ov_expiring_within_7_days
    • ov_expiring_within_30_days
    • ov_expiring_from_31_to_60_days
    • ov_expiring_from_61_to_90_days
    • ev_expired_in_last_7_days
    • ev_expiring_within_7_days
    • ev_expiring_within_30_days
    • ev_expiring_from_31_to_60_days
    • ev_expiring_from_61_to_90_days
  • Added fields to the dcv_expiration object
    You can now submit a request that returns the following fields in the dcv_expiration object: ov_shortened, ov_status, ev_status, and dcv_approval_date. These fields only return if your request includes the newly added query string filters[include_validation_reuse_status]=true.
  • Added dcv_method filter
    We added the option to filter domains by domain control validation (DCV) method. To use this filter, append the query string filters[dcv_method]={{value}} to the request URL. Possible values are email, dns-cname-token, dns-txt-token, http-token, and http-token-static.

Enhanced API: Domain info
You can now submit a request to the Domain info endpoint that returns the following fields in the dcv_expiration object: ov_shortened, ov_status, ev_status, and dcv_approval_date. These fields only return if your request includes the newly added query string include_validation_reuse_status=true.

New API: Expiring domains count

We added a new endpoint that returns the number of domains in your account with expired or expiring OV or EV domain validations. For more information, see Expiring domains count.

*On September 27, 2021, the expiration date for existing OV domain validations will shorten to 397 days from the date validation was completed. Learn more about this policy change: Domain validation changes in 2021.


Multi-year Plans now available

We are happy to announce that Multi-year Plans are now available in CertCentral and CertCentral Partners.

DigiCert® Multi-year Plans allow you to pay a single discounted price for up to six years of SSL/TLS certificate coverage. With Multi-year Plans, you pick the SSL/TLS certificate, the duration of coverage you want (up to six years), and the certificate validity. Until the plan expires, you reissue your certificate at no cost each time it reaches the end of its validity period.

The maximum validity of an SSL/TLS certificate will go from 825 days to 397 days on September 1, 2020. When the active certificate for a Multi-year Plan is about to expire, you reissue the certificate to maintain your SSL/TLS coverage.


Browser support for TLS 1.0 and 1.1 has ended

The four major browsers no longer support Transport Layer Security (TLS) 1.0 and 1.1.

What you need to know

This change doesn't affect your DigiCert certificates. Your certificates continue to work as they always have.

This change affects browser-dependent services and applications relying on TLS 1.0 or 1.1. Now that browser support for TLS 1.0 and 1.1 has ended, any out-of-date systems will be unable to make HTTPS connections.

What you need to do

If you are affected by this change and your system supports more recent versions of the TLS protocol, upgrade your server configuration as soon as you can to TLS 1.2 or TLS 1.3.

If you do not upgrade to TLS 1.2 or 1.3, your webserver, system, or agent will not be able to use HTTPS to securely communicate with the certificate.

Browser TLS 1.0/1.1 deprecation information

Firefox 78, released June 30, 2020

Safari 13.1, released March 24, 2020

Chrome 84, released July 21, 2020

Edge v84, released 7/16/2020

Helpful resources

With so many unique systems relying on TLS, we can't cover all upgrade paths, but here are a few references that may help:


CertCentral Services API: Updated error message documentation

In the Services API documentation, we've updated the Errors page to include descriptions for error messages related to:

  • Immediate DV certificate issuance
  • Domain control validation (DCV)
  • Certificate Authority Authorization (CAA) resource record checks

Earlier this year, we improved the APIs for DV certificate orders and DCV requests to provide more detailed error messages when DCV, file authorization, DNS lookups, or CAA resource record checks fail. Now, when you receive one of these error messages, check the Errors page for additional troubleshooting information.

Industry standards change

As ofJuly 31, 2019 (19:30 UTC), you must use the HTTP Practical Demonstration DCV method to demonstrate control over IP addresses on your certificate orders.

For more information about the HTTP Practical Demonstration DCV method, see these instructions:

Currently, industry standards used to allow you to use other DCV methods to demonstrate control over your IP address. However, with the passing of Ballot SC7, the regulations for IP address validation changed.

Ballot SC7: Update IP Address Validation Methods

This ballot redefines the permitted processes and procedures for validating the customer's control of an IP Address listed in a certificate. Compliance changes for Ballot SC7 go into effect on July 31, 2019 (19:30 UTC).

To remain compliant, as of July 31, 2019 (19:30 UTC), DigiCert only allows customers to use the HTTP Practical Demonstration DCV method to validate their IP addresses.

Removing Support for IPv6

As of July 31, 2019 (19:30 UTC), DigiCert has removed support for certificates for IPv6 addresses. Due to server limitations, DigiCert is unable to reach out to IPv6 address to verify the file placed on the customer's website for the HTTP Practical Demonstration DCV method.


We fixed a bug where the SSL/TLS certificate Order# details page and Order details panel weren't showing domain control validation as being completed after you finished validating the domains on your certificate order.

Note: This bug didn't stop your certificate orders from being issued after you completed the domain control validation.

Now, when you complete the domain control validation for the domains on your order, the Order# details page and Order details panel for the order show the domain validation as being completed.

(In the sidebar menu, click Certificates > Orders. On the Orders page, in the Order # column of the certificate order, click the order number or Quick View link.)
