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…

    Encrypt and upload files to IPFS from browser▲73

    Hi HN, I'm building ThirdCloud with the goal to replace Google Drive for everyone: more private, cheaper & maybe better UI/UX. So far, I've successfully implemented the main feature, which involves uploading and downloading files. Files are encrypted before being sent to IPFS network. Would like to hear your thoughts on this proof of concept.
