E-mail certificates

The Certification Authority (CA) of the University of Paderborn offers users the issuing of SSL user certificates as well as PGP certificates for encrypting and signing e-mails. With an e-mail certificate of the CA of the University of Paderborn you can provide your e-mail with an electronic signature. This signature guarantees the recipient of your e-mail the following characteristics:

• The e-mail was actually written by you and not by another person on your behalf, because only you are in possession of the private key belonging to the signature.

• The signer is a member (employee or student) of the University of Paderborn.

• The content of the transmitting e-mail has not been changed on the way to the recipient.

Please note that these points are in no way guaranteed when sending a "normal" unsigned e-mail. Although an e-mail contains the name and address of the sender, the sender can set these details in his e-mail program as he wishes and thus manipulate them.
