# UniHGW-CA Documentation

This source describes the university-internal Certificate Authority (CA) provided by the Universitätsrechenzentrum (URZ) at the Universität Greifswald.

## Key Information
- **Purpose**: To ensure operational independence from external CAs, preventing external policy changes from impacting internal university operations.
- **Current Version**: The active CA certificate is `UniHGW-CA-2032.pem` (valid until 2032).
- **Usage Restrictions**: 
    - **Not for public use**: Because these certificates are not pre-installed (anchored) in web browsers or email clients, they must not be used for public-facing web servers or general email correspondence.
    - **Permitted use**: Intended for internal purposes, such as internal university web servers.
- **VPN Migration**: The URZ is migrating user certificates used for VPN access to the UniHGW-CA.

## Support
Technical issues are handled via the URZ ticket system (hosted on [[groupware]]) or the Campus-IT hotline.
