# DFN-PKI Certificates

**DFN-PKI Zertifikate** are Public Key Infrastructure certificates provided through the DFN (Deutsches Forschungsnetz) for secure authentication and encryption within the research and education community.

## Types of Certificates
The DFN-PKI framework at the university encompasses several types of certificates:
- [[nutzerzertifikate]]: General user certificates.
- [[email-zertifikate]]: Certificates for S/MIME email signing and encryption.
- [[gruppenzertifikate]]: Certificates for functional/group accounts.
- [[serverzertifikate]]: Certificates used to authenticate servers and enable SSL/TLS.
