Which certificate type provides ownership of a particular domain by proving ownership through email authorization or publishing a text record?

The certificate type that provides ownership of a particular domain by proving ownership through email authorization or publishing a text record is Domain Validation (DV) certificates. DV certificates are designed to assure that the entity requesting the certificate does indeed control the domain in question.

When an organization requests a DV certificate, they are required to undergo a validation process that typically involves verifying that they have access to a specific email address associated with the domain or adding a specific DNS text record to demonstrate ownership. This process is relatively straightforward and allows for quicker issuance compared to more complex certificate types.

In contrast, the other certificate types serve different purposes:

• General purpose certificates usually refer to certificates that are not specifically tailored for any unique validation type or purpose.

• Extended Validation (EV) certificates require a more rigorous vetting process, including the verification of the legal identity of the entity requesting the certificate, which goes beyond simply confirming domain ownership.

• Wildcard certificates allow for securing multiple subdomains under a single domain name but do not change the method of ownership validation.

Thus, the correct answer focuses on the specific process used in DV certificates to establish and affirm control over a domain.
