A Wildcard SSL Certificate enables SSL encryption on multiple subdomains using a single certificate. Subdomains on the certificate must all share the same primary domain.
For instance, example.com, www.example.com, blog.example.com, store.example.com, and billing.example.com could all be secured using the same wildcard SSL as they all use the same primary domain. However, billing.yoursitesdomain.com could not be used with this certificate, as it is using a different primary domain.
HostGator offers SSL certificates from Comodo, providing a range of options to secure and protect your sites.
The Positive Wildcard SSL
HostGator is pleased to offer Comodo's Positive Wildcard SSL. This offers 2048 bit signatures and up to 256 bit encryption to protect both your domain and unlimited subdomains. Installation is free (to cover your primary domain and your first five subdomains - additional subdomains are $5 each for installation) and Comodo backs the Positive Wildcard SSL with a $10,000 limited warranty!
The Positive Wildcard is only $119.99 per year and can be ordered for up to three years via this form.
Subdomain Reissuing for Comodo
Each time you wish to have an additional subdomain load securely with https, the virtual host entries for the subdomain need to be added manually by our administrators. This is true even for new subdomains created through cPanel. Anytime you would like a new subdomain to load securely with the wildcard SSL, a re-issue request via phone or Live Chat will be necessary in order for it to work correctly.
We can also install this type of SSL on multiple servers. The fee is $25 for each additional server, with a limit of 100 servers maximum.
For installing a Wildcard SSL purchased elsewhere, we charge $25 + $5 for each additional subdomain after the first 5. However, we install this for free on a HostGator managed dedicated server plan.
