No more file validation for Wildcard SSL

Urgent DCV Changes for Wildcard certificates

There will be no more file validation for Wildcard SSL from 15th November 2021.

CA/B Forum changes

DCV is a process by which a CA learns that a domain is managed by the applicant for a certificate. Three options are currently available to confirm that you are an admin on the domain submitted in the SSL activation request:

  • Email-based validation (admin@, administrator@, webmaster@, postmaster@, hostmaster@ or WHOIS email)
  • File-based validation (HTTP/HTTPS validation)
  • DNS-based validation (CNAME validation)

In accordance with CA Browser (CA/B) Forum ballot SC45; the File (HTTP/HTTPS) validation method (DCV) will no longer be available for Wildcard SSL certificates and SAN items as of 15th November 2021.

Available DCV methods for Wildcard SSL

Validation for *.domain.tld will be restricted to only two methods:

  • Email-based validation (admin@, administrator@, webmaster@, postmaster@, hostmaster@ or WHOIS email)
  • DNS-based validation (CNAME validation)

From 15th November 2021, HTTP/HTTPS File validation will no longer be available.
