I need a certificate for my (WCF) web services. My company's web site (www.company.com) may or may not be the location for the web service, so I don't want to use the www URL when I create my SSL cert and build my web clients. Is there a prefix that is commonly used for web services (e.g. service.company.com)?

No, there is no such prefix, but you can get a wildcard certificate that is valid for *.company.com. Then you can decide later.

  • How does that work? I'm pretty sure that WCF (and IIS) will issue a warning if the host name doesn't match the common name on the SSL certificate. – Quark Soup Jan 01 '17 at 16:47
  • See e.g. this wikipedia article as a starting point: https://en.wikipedia.org/wiki/Wildcard_certificate – Marc Balmer Jan 01 '17 at 16:49
  • This looks promising. Found this note about using it specifically with WCF: http://stackoverflow.com/questions/24385815/wcf-over-https-using-a-wildcard-ssl-certificate. – Quark Soup Jan 01 '17 at 16:53
  • Apparently you don't get something for nothing. The wildcard certificate is significantly more expensive than the single site. – Quark Soup Jan 01 '17 at 18:41
