Flashpaper: Self‑destructing secret sharing tool that requires no database

Flashpaper was announced on Hacker News as a new web service for secret sharing. It encrypts data client‑side before transmission. The encrypted payload is stored as a URL fragment, eliminating server‑side storage. Recipients can retrieve the secret using the link, after which it self‑destructs. Because no database is used, the service reduces risk of data breaches. The design relies on modern browsers' cryptographic APIs. Users are encouraged to test the tool for one‑time confidential exchanges. The project’s source code is available for review on its website.
