Developer builds end-to-end encrypted pastebin where server can't read data

A developer created hidetext.sh, a pastebin that encrypts text in the browser before sending it to the server, using the Web Crypto API with AES-GCM. The encryption key is stored in the URL fragment, which is never transmitted to the server, ensuring zero-knowledge. The service also supports optional burn-after-read, though handling simultaneous reads required a simple first-fetch deletion approach.
