Show HN: Drop – Self-destructing encrypted messages

• privsen 10mo ago
  Scratched my own itch. Needed to share passwords without them sitting in chat logs forever. Client-side AES-256-GCM, PBKDF2 key derivation. Server just holds encrypted blobs until expiry. Questions welcome.

    There's nothing self-destructing about your server dropping data, after a decision on (unencrypted) meta data (timeout, number of views).

      Yeah fair.. self-destructing is overselling it. Server drops the blob after timeout/view count. Server sees expiry, view count, salt, iv. Content is encrypted, metadata isn't. Can't avoid this with server-managed TTL - alternative is client-only expiry but then you're trusting the recipient's browser. Main point is credentials don't live forever in chat history. Smaller window, not magic.
