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!
Nice, but please stop with the words "forever" when it's about costs, ie: "free forever". It harms your message.
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"
