I own example.com, and I'd like to get an SSL cert. Normally I would simply buy a wildcard cert, so that I can add subdomains for future purposes.
However, I need to let a trusted 3rd party operate a subdomain of my site: 3rdparty.example.com. Our site will link to theirs for some specific functionality. We will keep the site look and feel the same so that users don't get confused. For the same reason we'd like to keep the 3rd party site under our domain.
What kinds of SSL certs do I need to buy for this scenario? They want me to buy the cert for the 3rdparty subdomain and send it to them.
The 3rd party is not competent, and I've never had to dive very deep into SSL. Based on the feedback and additional reading, I will outline the CSR fields (so they don't misspell anything) and ask them to create the CSR and send it to me. I will then apply for the 3rdparty.example.com cert, which according to godaddy also applies to www.3rdparty.example.com. There is no need for me to ever touch the private key used to sign the CSR, I can revoke the certificate using godaddy's web console if needed.
Can I still get a wildcard ssl cert for myself for *.example.com, or will this cause a conflict somehow? I haven't seen this exact scenario addressed anywhere.
