SSL certificate for server

Organisational units at the University of Vienna can equip their servers with SSL certificates to establish an encrypted connection between the server and the user’s device.

An SSL certificate contains detailed information about the server to which you connected. It aims to guarantee that the owner of a website is in fact who they say they are.

The IT representatives are mainly responsible for ordering and managing the SSL certificates.

Renewing an SSL certificate

New SSL certificates are valid for a maximum of 1 year. If necessary, it can be renewed before the end of the validity period.

From a technical point of view, a certificate is not extended when it is renewed, but reissued. If you apply for a renewal via the Enrolled Certificates page, you only need to replace the certificate after it has been issued, but not the Private Key on the server.
