New digital certificates for the wireless LANs eduroam, Uni-Mainz and VPN-Server

On October 6th, new digital certificates will be activated for the wireless LANs "eduroam" and "Uni-Mainz", as well as for the VPN servers.


What does that mean for you?

Not much will change for you. The new digital certificate is either automatically accepted - depending on the operating system or device - or you have to confirm that you accept the new certificate when asked. Some devices show the name, others a so-called fingerprint of the digital certificate.

What are digital certificates?

A digital certificate is an electronic proof of authenticity that certifies the identity of a computer or an organization. You can also compare this to an identity card in real life. Due to the legal framework and to prevent misuse, we are obliged to renew the certificates for these services on a regular basis.
