DID YOU KNOW : Windows mobile and wildcard certs don’t work together

Filed under: DID YOU KNOW,Technology,Windows — Vinay @ 11:32 pm

Wildcard SSL certificates allow you to use one certificate for all sub domains (up to one level) of a host. Say I got a wildcard SSL certificate for *.kudithipudi.org, I would be able to use it to provide SSL on blah.kudithipudi.org, ssltest.kudithipudi.org, youcannotbeserious.kudithipudi.org and the clients won’t complaint about it.

For some reason though, Windows Mobile phones don’t like wildcard certs. So if you are ever scratching your head, why every other client works, but windows mobile devices don’t..stop scratching and get a regular SSL certificate for your website/application.

Apparently, this is the case with

  • Windows CE
  • Windows Mobile 5.0
  • Windows Mobile 6.0
  • Windows Mobile 7.0

Don’t you get the feeling that someone keeps using the same library and never bothered to check/fix it? And searching on MSDN or any other Microsoft resource won’t provide you this information. This is my own deduction after beating my head against the wall for more than 3 days :).
