SSL certificates are used to secure communications between a website, host, or server, and end users that are connecting to that server. An SSL certificate confirms the identity of the domain name (e.g., www.gmu.edu) that is operating the web site, encrypts all information between the server and the visitor, and ensures the integrity of the transmitted information.
- Certificate types include:
- Single domain: default.
- Multi-domain: a host or application answers to multiple names.
- Wildcard: for cases where a department has all of their systems under the same subdomain and chooses to protect them all with a single certificate (Note: Cannot be gmu.edu).
- Certificates have a lifetime of 2 years maximum.
- Certificates may be renewed.
