Question: what is the difference between an ssl certificate and a wildcard ssl certificate?
Answer: Wildcard SSL Certificate. ... The difference between a single domain SSL and a Wildcard SSL is that the Wildcard SSL has a prefix '*' known as the Wildcard character, which is added to the domain name. So, '*' could be 'mail,' 'login,' 'ftp,' or anything else. In fact, the number of subdomains can be unlimited.
