Security certificates are needed when vulnerable content is transmitted via the Internet (encryption) or when the communication partner’s identity has to be confirmed (authentication, signature). An important example is the transmission of a password. The password has to be encrypted for the transmission process and the computer which is requesting this password has to identify itself. Server certificates can be used for this purpose. For email exchanges, the communication partners can ascertain each partner’s identity if the partners have electronically signed their email. In addition, the confidentiality can be guaranteed if the certificate of the receiver is used for the encryption. In specific cases, instead of a password, a certificate can be used for authentication, e.g., Grid certificates are sometimes used for Grid projects.

The following certificates can be issued via the URZ:

S/MIME (email) certificates

If a university employee wants to sign or encrypt their emails, they can request an official and personal certificate (DFN safety level Global) for this purpose from the URZ.

Server certificates

If you want to offer encrypted connections (https) to decentralized servers, you can request a server certificate (DFN safety level Global) from the URZ. This type of certificate is accepted by all important browsers and email clients.

Grid certificates

Employees of the University who participate in Grid projects like DEISA and LCG can receive a certificate for these projects via the URZ.
