20140609 - Introduction of wildcard SANs for Comodo UC certificates

With TBS INTERNET it is now possible to include wildcard SANs (domain name in the form *.domain.ext) to Comodo UC and Comodo SHA256 UC certificates.

A sole certificate can then really secure an infinite number of domains and sub-domains and even several levels of sub-domains (such as *.domain.ext and *.sub-domain.domain.ext)!

How does it work?

The CSR generation and the order process is the same than for a classical order of Comodo UC certificates: Generate your certificate by indicating the main domain for the CN field. Copy / paste the CSR in the order form and enter the list of addtional domains (the main domain cannot be a wildcard one).

Tariffs

The calculus is simple: 5 standard SANs count for 1 wildcard SAN. Only constraints: the first 3 SANs of the certificate (including the main domain) cannot be used to secure a wildcard domain.

In a schematic way:

Can I add a wildcard SAn to an existing certificate?

Yes. You can add a wildcard SAN via reissuance. The reissuance is free, only the needed additional SANs will be invoiced.

What if I delete a wildcard SAN from my certificate?

if you included a wildcard SAN to your certificate and want to delete it via reissuance, you'll then have 5 standard SANs available fot your other needs.
