Jens Reimann

Jens Reimann is an independent German developer who focuses on lean, protocol-level tooling for modern cloud-native environments; his catalog is intentionally narrow, concentrating on standards-based utilities that let DevOps teams wire identity into automated pipelines without dragging along heavyweight SDKs or graphical consoles. The centerpiece is a compact OIDC command-line client that speaks plain OAuth 2.0 and OpenID Connect: it can run a browser-free authorization-code flow, cache the resulting JWT, emit the access token to stdout for curl or kubectl, refresh it in the background, and logout when the job is done. Typical use cases include scripting unattended CI jobs that must exchange short-lived tokens with Keycloak, Auth0, Azure AD or Google Identity, fetching ID tokens for service-mesh authentication, or temporarily elevating Kubernetes cluster rights without storing long-term kube-config secrets. Because the utility is delivered as a single static binary with no runtime dependencies, it slips easily into Alpine containers, GitHub Actions, or Ansible playbooks, giving security teams a reproducible way to enforce least-privilege access across fleets of ephemeral workloads. The publisher’s software is available for free on get.nero.com, where downloads are pulled through trusted Windows package sources such as winget, always install the latest release, and can be queued for batch installation alongside other applications.
