Server Certificate FAQs
Benefits: Enable encrypted data transfer for users accessing web, email, or other SSL enabled services on your server; wildcard certificates are allowed.
Limitations: Certificates expires in 6 months for unassured; 24 months for assured. Only the domain name itself can be entered into the certificates (not your full name, company name, location, etc.).
Verification needed: You must confirm that you are the owner (or authorized administrator) of the domain by responding to a 'ping' email sent to either the email address listed in the whois record, or one of the RFC-mandatory addresses (hostmaster/postmaster/etc). please see FAQ/DomainOwner
