> but if your blog is as "blog.yourdomain.com" then you need to get a wildcard SSL Certificate. I don't think so. You can select any subdomain you want when you buy a certificate. Obviously if you get a cergificate for blog.yourdomain.com then it does not work on www.yourdomain.com. If you only need these two subdomains, buying two separate certificates is cheaper than a wildcard one.
