双语域通配符SSL证书？

Question

I work on a web application with a wildcard cert -- multiple environments all as subdomains of the root domain, works pretty well.

The application is bilingual (english/french), and supports switching between the two, but the domain name remains english. Someone asked me about supporting a French domain name recently, and that sent me off into research mode.

There are apparently internationalized domain names and although the punycode domain feels pretty weird, the user experience seems ok. And there are multi-domain SSL certificates, which I guess would work if we weren't already using a wildcard certificate. Can you get a multi-domain wildcard cert so that you could accept requests on *.cats.ca and *.chats.ca (generic example of a domain name in french and english) or *.cats.com and *.gatos.com for an english/spanish site in America, where a single website host could respond to requests in SSL for subdomains of both domains?

I tried searching, didn't find much -- and I'm not totally convinced this is the right stack exchange, but most of the SSL cert questions I found were here.

Answer 1

There are certificates that do support multi domain wildcards. For example, this one issued by Comodo and another one issued by Digicert . You can probably check with your certificate provider on the availability and cost of such a certificate.

Answer 2

I agree with Anand's answer, Multi Domain Wildcard SSL certificates can protect both multiple domains and their unlimited number of sub-domains.
