I've scoured the web for a clear and concise answer to my SSL question, but to no avail. So here goes: I have a web-service requiring SSL support for authentication pages. The root-level domain does not have the "www" - i.e., secure://domain.com - but localized pages use "language-code.domain.com", i.e. secure://ja.domain.com So I need at least a wildcard SSL certificate that supports secure://*.domain.com However, we also have a public sandbox environment at sandbox.domain.com, which we also need to support under localized domains - so secure://ja.sandbox.domain.com needs to also work. The previous admin managed to purchase a wildcard SSL certificate for .domain.com, but with a Subject Alternative Name for "domain.com". So, I'm thinking of trying to get a wildcard certificate with SANs defined as "domain.com" and ".*.domain.com". But now I'm getting confused because there seem to be separate SAN certificates, also called UCC certificates. Can someone clarify whether it's possible to get a wildcard certificate with additional SAN fields, and ultimately what the best way is to support: secure://domain.com secure://.domain.com secure://.*.domain.com with the fewest (and cheapest!) number of SSL certificates? Thanks!
