SSL certificates

Any service accessible via SSL (https) must have an SSL certificate. This includes any web server with encrypted or "secure" content. An SSL (Secure Socket Layer) certificate is a signed electronic guarantee that a particular server is the server it claims to be. Certificates are used primarily (but not exclusively) for providing web pages via an encrypted connection. A certificate is signed by a Certificate Authority (CA) which ensures the integrity of the certificate.

A few Certificate Authorities such as Verisign, Thawte, and GlobalSign are automatically trusted by SSL clients (including web browsers), so certificates signed by these companies are validated without user confirmation. Until recently C&CZ signed its own certificates but now all certificates of servers and web applications are signed by GlobalSign (through SURFdiensten). This means that the former root certificate of C&CZ (certificate.science.ru.nl) is no longer needed.

Obtaining a certificate

Because SSL certificates are used as proof of the validity of the web site or server, it is not possible to acquire a signed SSL certificate for just any domain name. The Certificate Authorities check if the person or organisation requesting a certificate is indeed the owner of the domain name for which the certificate is requested. Domain names [[Domeinnaam registratie|registered] through C&CZ are owned by the Radboud University. Therefore C&CZ can also request SSL Certificates for these domain names.
