What it does
Encrypted cloud storage that encrypts files in your browser before upload, with a post-quantum default cipher (ML-KEM-1024). The server only ever sees ciphertext. EU-hosted, 20 GB free, open-source crypto you can audit. No AI, no trackers.
End-to-end encrypted cloud storage: files are encrypted on your device, so our servers never see plaintext. A private, post-quantum Google Drive alternative.
Secure encrypted cloud storage. Even we cannot read your files. Privacy isn’t a promise. It’s the architecture. We never hold your key . Keys are generated on your device and never sent to us. Inspect the crypto yourself . @shieldfive/crypto is public on GitHub. GDPR-aligned data processing, hosted in the EU . Encrypted files and the database stay in the EU, under an Article 28 DPA you can read before you sign. ML-KEM-1024 by default . NIST Level 5, the highest standardized. By default. Drop a file below to run a real browser encryption. Nothing is uploaded, your file never leaves this page. Open your network tab and watch. The real product applies this exact principle to your full cloud…from shieldfive.com

Ellipticc Drive – open-source cloud drive with E2E and PQ encryptionOct 2025 · ellipticc.com · ▲21Hey 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…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
