I'd love some suggestions for a not too expensive cert I can use on a subdomain. I don't care if it's verisign or pumped up with logos, I just care whether it generates warnings in people's browsers (bad!). Any suggestions?
ANY ssl cert can be used on a sub domain. The same requirements apply - like the subdomain will need to have a dedicated IP address, and you'll need to generate a Certificate Signing Request (CSR) for the sub domain.
You have to just generate the SSL for the subdomain for it to work. Try http://www.namecheap.com , they got cheap SSL there.
