In the past few days, there have been uncertainties and concerns about the LUKS (“Linux Unified Key Setup”) disk encryption, which is widely used on Linux. We publish our assessment of this here.

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.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…

the cloud is a walled garden built for profit [ not efficiency ]. you’re paying for idle, autoscaling is too slow, and serverless is a scam. locked in, overcharged, and out of options. lttle.cloud is different. decentralized, open-source, and built for real performance [ sub-10ms cold start ], true pay-for-what-you-use pricing, and zero vendor lock-in. deploy anything as "serverless" from any docker image, no rewrites, no bullshit. powered by the blockchain and built in public, it’s transparent, efficient, and free from vendor lock-in. run your own private cloud or join the decentralized…

I reposted, since i forgot the Show HN prefix. When I looked at self-hosted options, true E2EE turned out to be surprisingly rare. Most solutions rely on disk encryption, which only protects against physical theft, not server compromise or admin access. So I built Agam Space, my attempt at a self-hosted alternative to Mega or Proton Drive. It uses proper zero-knowledge encryption. Files are encrypted in the browser, and the server only stores encrypted blobs. Admins literally cannot access the files. It’s still in early beta, with very basic functionality and no professional security audit…

Hi HN, I’m the creator of Cordum. I’ve been working in DevOps and infrastructure for years (currently in the fintech/security space), and as I started playing with AI agents, I noticed a scary pattern. Most "safety" mechanisms rely on system prompts ("Please don't do X") or flimsy Python logic inside the agent itself. If we treat agents as autonomous employees, giving them root access and hoping they listen to instructions felt insane to me. I wanted a way to enforce hard constraints that the LLM cannot override, no matter how "jailbroken" it gets. So I built Cordum. It’s an open-source…

Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

I made a simple site that allows you to upload files. It requires no sign up and 100% free. The biggest advantage is that it returns you the direct URL to your file. So you can use it to store images for MD-based forum posts. Or put in your site's . I use the Cloudflare R2 storage which offers zero egress fees. So I pay $0 of transfer costs. I added a simple anti-nsfw files check and a simple anti-malware check. Please do not try to break it. Thanks! (>‿◠)

Needed this in my own work, anonymizing PII/PHI and decided to build this because presidio didn't really cut it for our use-case. Try it and maybe let me know if you have any feedback :)

Disclaimer it is a heavily AI assisted project. The goal was not to be the most performative but the kind that's easier to learn from. I wanted to share this in case there are people who had the same idea or wanted to see something like this.

How do you protect your digital assets? Do you store your personal notes, dog pictures, cat videos, music playlists, health records, bank statements, and government documents in the cloud, on your phone, a usb, hard-disk, solid-state, or network drive? Is your data available to you, when and where you need it? Can your data be viewed by anyone else? Is your data stored in multiple locations or are all your eggs in one basket? Can your data be changed or deleted without your knowledge? S P A C E[1] is an open source project[2] combining End-to-End Encryption with Proof-of-Work Blockchains to…
