A wildcard certificate is a digital security certificate which can be used with multiple sub-domains of a domain. Compared to conventional SSL certificates, using a wildcard certificate can not only be cheaper, but also more convenient than having a certificate for each domain. The principal use of wildcard SSL certificates is for securing websites with HTTPS (HyperText Transfer Protocol Secure), but there are also other applications in a variety of fields. The HTTPS encryption is intended to provide benefits like integrity, confidentiality and identity.
How does a wildcard certificate work?
Wildcard notation consists of two elements that are inserted before the domain name – an asterisk and a period. The asterisk in the common name is the wildcard character that can take on any first-level sub-domain name. The assumed value must not have a period in it. For example, if you host your website at www.your-domain.com, a wildcard certificate for *.your-domain.com would allow you to secure first-level sub-domains such as:
Nowadays, unlimited SSL server licenses are a standard feature for the full range of SSL certificates including wildcard certificates. This means that the owner is entitled to install the certificate to as many server machines as he or she wants at no extra cost. Please note that the above naming scheme remains the same for all additional servers.
What are the advantages of using a wildcard certificate?
The main advantage of wildcard certificates is that they help server administrators saving hundreds, sometimes even thousands of dollars on SSL certificates by enabling them to secure the parent and sub-domains over a single fully qualified domain name (FQDN) at no extra cost. Another great advantage is the feeling of security that comes from knowing your entire website is protected by the most trusted and reliable SSL management in the industry.
In addition, when using a wildcard certificate in conjunction with so-called Subject Alternative Names (SANs), you save even more money. SANs are also known as Unified Communications SSL Certificates (UCC SSL) and are mainly used for Unified Messaging and Microsoft Exchange, one of the leading business e-mail and calendar solutions. What’s more, most wildcard certificates use a strong 256-bit encryption, giving customers a secure environment to shop.
