About This Launch
SEAL is a file-sharing service for sensitive files. Files are encrypted in the browser before upload, so the backend receives ciphertext rather than the original file. The per-file decryption key stays in the URL fragment and, in the normal browser flow, is not sent to the server. The basic web flow requires no account or email. Senders can set expiry, single-use access, open/download limits, password or OTP protection, and revoke access.
Why I Built This
I wanted secure file sharing to feel as simple as dropping a file and getting a link, without forcing the sender or recipient into another account-based portal.
