Show HN: Ellipticc Drive – open-source cloud drive with E2E and PQ encryption
ellipticc.comHey HN, I’m Ilias, 19, from Paris.
I built Ellipticc Drive, an open-source cloud drive with true end-to-end encryption and post-quantum security, designed to be Dropbox-like in UX but with zero access to your data, even by the host.
What’s unique:
Free 10GB for every user, forever.
Open-source frontend (audit or self-host if you want)
Tech stack:
Frontend: Next.js
Crypto: WebCrypto (hashing) + Noble (core primitives)
Encryption: XChaCha20-Poly1305 (file chunks)
Key wrapping: Kyber (ML-KEM768)
Signing: Ed25519 + Dilithium2 (ML-DSA65)
Key derivation: Argon2id → Master Key → encrypts all keypairs & CEKs
Try it live: https://ellipticc.com
Frontend source: https://github.com/ellipticc/drive-frontend
Would love feedback from devs and security folks — particularly on encryption flow, architecture, or UX.
I’ll be around to answer every technical question in the comments!
Your "About" links seem not to work. In my case I was interested in where data is hosted, and the only information I see (from your HN post) is that you are from Paris. Does this mean EU hosting (which is good)?
Your post here says ML-KEM768 but the website says Kyber512.
Also, this SRP implementation seems a bit... sus.

"Open Source" is a pretty clear case of lying by omission.
You open sourced the frontend. Without a clear license.
That's not an "open-source cloud drive"
