Obscurus is a simple web-based tool for sharing secrets via a short-lived one-time-use link.

Obscurus requires Vault in Kubernetes. The easiest way to spin up a dev
environment is by using Tilt. Prepare a local Kubernetes
cluster with something like k3d, then simply
run tilt up. To access the web UI, run
kubectl -n obscurus port-forward svc/obscurus 8000:80 and access
http://localhost:8000 in your browser.
