これは何？

binthere is a zero-knowledge pastebin for sharing short secrets such as credentials, private messages, or code snippets. The browser generates a random 256-bit key and encrypts the note with AES-256-GCM before any network request is made. Only ciphertext is uploaded, and the key is appended to the share link after the # fragment, which browsers never send to the server.

Each note is one-time view: the first reader atomically consumes it, and later visitors receive a 410 Gone response. Unread notes are deleted automatically after 24 hours. An optional password is mixed into key derivation, so neither the link nor the password alone can decrypt the note. Losing the link means the note cannot be recovered, since there are no accounts or server-side index.

The project runs as a single Cloudflare Worker using Static Assets, Workers KV, and a Durable Object for burn-after-read. It ships with an official npm CLI that uses the same protocol, and it can be self-hosted within Cloudflare's free tier.

主な機能

  • 01Client-side AES-256-GCM encryption; the server only stores ciphertext.
  • 02One-time view with atomic consumption, so only one reader gets the note.
  • 03Automatic deletion of unread notes after 24 hours.
  • 04Optional password layered on top of the link key.
  • 05Safe Markdown rendering with syntax highlighting, QR codes, and delete links.
  • 06Official CLI published to npm with an interactive menu and pipeline support.

ユースケース

  • Sending a password or API token to a colleague without leaving it in chat history.
  • Sharing a one-off private message that should not persist on a server.
  • Passing a code snippet or config that should be read once and then disappear.
  • Scripting secret hand-offs from a terminal with the CLI.
