--- seo: title: shhh — self-hosted zero-knowledge pastebin description: Share secrets that expire on their own. The server stores ciphertext and nothing else — the decryption key lives in the URL fragment and never reaches it. Self-hostable with Docker in one command. --- ::u-page-hero #title Say it once. We'll forget. #description A self-hostable, zero-knowledge pastebin for sharing secrets — text and files — that expire on their own. The server stores ciphertext and nothing else. The decryption key lives in the URL fragment, which browsers never send. #links :::u-button --- color: neutral size: xl to: /getting-started/introduction trailing-icon: i-lucide-arrow-right --- Get started ::: :::u-button --- color: neutral icon: i-simple-icons-github size: xl to: https://github.com/thoda-dev/shhh variant: outline --- Source ::: :: ::u-page-section #title Built for the "send me the password" moment #features :::u-page-feature --- icon: i-lucide-lock-keyhole --- #title [Zero-knowledge]{.text-primary} by design #description AES-256-GCM in the browser.
