Every encrypted storage I checked — Proton Drive, Tresorit, ente.io — stops at classical crypto. Adversaries already harvest traffic to crack later with quantum machines. So I built StenVault with hybrid post-quantum encryption (ML-KEM-768 + X25519) — if either layer breaks, the other holds. I wrote my own PQC WASM package after finding gaps in the leading library. Auth is OPAQUE — server never sees your password. Try /send — encrypt and share, no account needed.

Hey everyone — I'm Gefson, solo developer behind StenVault. I started this project after reading about harvest-now-decrypt-later attacks: adversaries are already collecting encrypted data today, waiting for quantum computers to crack it open. I went looking for encrypted storage that addressed this. Proton Drive, Tresorit, ente.io — all solid, but none had a post-quantum layer. So I built one....
