User certificates are a kind of identity card. With their help, one can ensure that the data is
- originate from exactly the desired person (authenticity),
- were not falsified during transmission (integrity) and
- cannot be read by unauthorized persons (confidentiality).
This procedure is needed, for example, to establish trusted mail communication.
The whole thing works with similar to a pair of keys that belong together. Everything that was encrypted with one key can only be decrypted with the other key and vice versa.
One key is kept to itself (private key), the other is made accessible in public (public key). To ensure that the public key really belongs to the person specified, it must be authenticated like an ID card. This task is performed by the certification authority (AC). The HRZ operates its own certification body at the DFN Association (CA). The CA's name is "HS Emden/Leer CA".
