Secure one-time secret sharing tool

Overview

OTS (One-Time Secret) is a lightweight, open-source tool for sharing sensitive info like passwords or API keys securely.

Features include end-to-end encryption, custom expiration times, and optional password protection for links. Deployment is straightforward via Docker image or Node.js, allowing easy self-hosting on any server. It’s flexible for various infrastructure needs and prioritizes privacy by design.
