Wildcard SSL Certificate from DigiCert

Wildcard Certificates for Unlimited Servers & Subdomains.

DigiCert's WildCard Plus ssl certificates secure an entire domain -- a certificate for * will secure,, and any other subdomain of you can think of. We even useSANs to let your wildcard ssl certificate secure the base domain: And every DigiCert WildCard SSL Certificate comes with an Unlimited Server License, so you only pay once, whether you have one server or one hundred.

WildCard SSL Certificates from DigiCert give you the best in flexibility, compatibility, and value. Wildcard SSL is designed for system administrators who want to save time and get the most for their money, a WildCard Certificate is perfect for anyone who runs multiple subdomains or has multiple servers. Many government agencies, educational institutions, and large organizationssave thousands of dollars each year with WildCard Plus.

What you get:

Security for your entire domain. Any wildcard certificate for * will secure,, and any other subdomain of DigiCert's wildcard stands out by allowing you to secure ANY subdomain of the domain your certificate was issued to through the use of Subject Alternate Names, or even the base domain itself —— something no other wildcard currently offers.

Unlimited server license. Most SSL certificates are only licensed for one physical server. With DigiCert's unlimited server license, you can use your WildCard certificate on as many servers as you want. You can even generate separate certificates with unique key pairs for each server. It's the ultimate in flexibility.

SHA-2/SHA-1 2048-bit SSL certificates. SHA-2 may be necessary for PCI compliance or in accordance with federal regulations, and is available on all the certificates DigiCert offers as an option during the order process. SHA-1 encryption is also available for customers looking for secure encryption with greater certificate ubiquity thanSHA2 SSL certificates currently offer.

WildCard SSL Certificates - The DigiCert Difference

DigiCert's "WildCard Plus" SSL Certificates

Do you need one certificate to secure an entire domain with multiple subdomains ("," "," etc.)? Do you have multiple servers (web servers, mail servers, intranet servers, testing servers) that all need an SSL certificate? WildCard Plus, DigiCert's wildcard ssl certificate, is the product for you. WildCard Plus certificates have all the features you would expect from a wildcard certificate, along with a few features you may not get with other wildcards.

Why call it "WildCard Plus"

We added the "Plus" to the name because when you buy a DigiCert WildCard ssl certificate, you just get more:

  • More freedom. Our Unlimited Server License means you are free to use your certificate anywhere you like without having to pay us extra license fees. Put it on your web servers, your intranet servers, your mail servers -- put it on any server and any platform, and you don't have to pay us a dime extra.

    Your customer account has a simple "Duplicate Certificate" interface that allows you to issue as many certificates as you need to, quickly and for no extra charge.

  • More compatibility.WildCard certificates have a couple compatibility features that you won't find in traditional wildcard certificates:

    • Your own site. A typical wildcard certificate for "*" will work with names like " and," but not "" itself.

      This often comes as a disappointment to administrators who want to protect both and with the same certificate.

      DigiCert WildCard SSL resolves this problem by including the base domain in every wildcard certificate as a subject alternative name, a little-used but well-supported capability of SSL certificates.

      Even more, DigiCert WildCard ssl certificates are unique in allowing you to secure ANY subdomain of your domain, including multiple levels of subdomains with one certificate. For example, your WildCard for * com could include as a subject alternate name.

    • Mobile devices. WildCard Plus certificates allow you to choose up to ten specific subdomains ("," "," etc.) to list in the certificate, resolving issues some mobile devices have with the star (*) syntax of wildcard certificates.

      "Some of our customers have problems securely connecting to their company mail server, because their mobile devices do not support wildcard name matching," said Christopher Skarda, DigiCert's Director of Security Services. "We found that many of these mobile devices do support Subject Alternative Names. By putting the wildcard (e.g. '*') and the mail server name (e.g. '') into the same certificate, we found a way to enable devices to accept the specific host name. In the past, the only option was to purchase a separate SSL Certificate."

      And because this is done in our "Duplicate Certificate" interface -- instead of in the original certificate -- you can issue as many ssl certificates as you need to for as many subdomains as you need. So when we say "up to ten specific subdomains," that is per certificate, so our Unlimited Server License makes this unlimited too.

      Some server types, services, and devices do not work with wildcard ssl certificates. See them here.
