Zero-knowledge encrypted file storage. Post-quantum on by default — ML-KEM-1024 + XChaCha20-Poly1305, client-side, before anything reaches our servers. The crypto library is open source (Apache-2.0) and on npm, so you can diff it against what runs in your browser. EU-hosted. Built in the open by @chogarcia. No external audit yet, find the holes.

#introduction
ShieldFive — zero-knowledge encrypted file storage where post-quantum is the default, not a toggle.
Files are encrypted in your browser under ML-KEM-1024 + XChaCha20-Poly1305 (HKDF combiner) before they reach us. We only ever hold ciphertext.
The client-side crypto is a standalone Apache-2.0 library — the same code your browser runs, so you can diff what's published against what's served to you.
Honest limits up front: no external audit yet, browser-only client, anonymous share links are classical-only.
We'd rather you find the holes than not.
