Hey 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.jsCrypto: 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 & CEKsTry it live: https://ellipticc.comFrontend source: https://github.com/ellipticc/drive-frontendWould 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!

Could you build this?

Partial While client-side file storage and cloud storage wrappers are standard, implementing correct, audited post-quantum cryptography and robust zero-knowledge multi-user key management is nontrivial.

What it would actually take: The frontend is typically built in React/TypeScript leveraging Web Crypto API combined with post-quantum libraries (like Kyber/ML-KEM via WebAssembly). The backend requires S3-compatible blob storage with blind metadata indexation. The hard part is building side-channel-resistant client-side crypto, quantum-safe key exchange/ratchets, and secure key derivation without leaving cryptographic vulnerabilities that vibe coding easily introduces.

Discussion

16 comments analyzed.

Competitors mentioned: OneDrive (MS native integration), iCloud Drive (Mac native integration), Dropbox, Tarsnap

Concerns raised: Fake client testimonials on landing page, Only frontend open-sourced, backend closed, SRP implementation security concerns, Inconsistency: ML-KEM768 vs Kyber512, Misleading 'open-source' claim (frontend only)

Feature requests: Native OS remote storage API integration (better UX than WebDAV), Full remote storage/Dropbox sync support with E2EE, OPAQUE authentication instead of SRP, Settings and user profile pages (currently placeholders)

Competitors

Other products that read as similar to this one : 286 launches clear the similarity bar, closest 8 shown.

Attention rank: #85 of 287 (itself plus its competitors, highest first, normalized so YC and Product Hunt are compared fairly).

Looks like the first mover among its competitors.
