Christian Hohnstaedt

Christian Hohnstaedt is an independent developer whose open-source portfolio centers on XCA, a compact yet powerful Windows utility that streamlines every stage of public-key infrastructure deployment. The tool combines a graphical certificate authority workbench with a built-in database, letting administrators generate, import, sign, and revoke X.509 certificates, PKCS#10 requests, and RSA, DSA, or elliptic-curve key pairs without resorting to command-line complexity. Typical use cases range from issuing client and server certificates for internal web services, VPN gateways, and wireless networks to preparing code-signing or S/MIME credentials for developers and end-users. Integrated templates, subject-alternative-name wizards, and bulk operations accelerate roll-outs in enterprise labs, while support for hardware tokens and smart-cards keeps private keys under physical control. Certificate chains can be exported in PEM, DER, PKCS#7, PKCS#12, and a variety of other formats, ready for Apache, nginx, Postfix, or any TLS-aware application. A built-in validity monitor highlights impending expirations, helping DevOps teams avoid outages. Because the project is maintained in public repositories, security updates and new elliptic curves are incorporated quickly, giving auditors confidence in the cryptographic backend. All releases are accompanied by detailed change logs and reproducible Windows builds that run natively on 64-bit desktops and servers. The publisher’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest version, and can be queued for batch installation alongside other applications.
