Products that do what Twoway, a Go package for HPKE encrypted request-response flows does

Hey HN, I'm Willem from Confident Security, we've built CONFSEC, a provably private AI inference engine. Today, we're excited to open-source twoway: https://github.com/confidentsecurity/twoway twoway is a Go package that makes it easy to implement secure, encrypted request-response flows. It powers CONFSEC's blind prompt handling, ensuring no one, not even us, can see client requests. We built twoway on Cloudflare's circl/hpke, it uses Hybrid Public key Encryption to implement two flows: - A one-to-one flow where a sender communicates with a single receiver. This…

Dharma – Programmable Peer-To-Peer Loans Using Ethereum Smart Contracts▲156
Hey HN! My name's Nadav Hollander, and I'm the Founder of Dharma. Dharma is building an open-source library that makes it really easy to programatically borrow and lend cryptocurrencies using smart contracts on the Ethereum blockchain. Today we're launching our Alpha Testnet release -- a command line tool that allows you to 1. Access a line of cryptocurrency credit from the command line in under 5 minutes 2. Easily build a bot that auto-invests in loans under hyper-customizable, programmable criteria Check it out: https://github.com/dharmaprotocol/dharma-cli Why I Think…

gocryptfs, an aspiring successor to EncFS, now in v1.0▲20
Author of gocryptfs and co-maintainer of EncFS here. gocryptfs is a FUSE overlay filesystem for Linux like EncFS. But it is written from scratch in Go, uses modern crypto and fixes the security issues of EncFS while providing equivalent speed. Some of the key differences to EncFS are: * Just one security level roughly equivalent to EncFS "paranoia" mode, at the speed of "default" mode. * A design so simple it fits on one page ( this one: https://nuetzlich.net/gocryptfs/security/ ) * Explicit filesystem creation using "gocryptfs -init". No configuration prompts. *…

Hyprsqrl – open-source revolut you can self-host (live iban/sepa/ACH)▲9
Hi HN! Ben here from hyprsqrl, and I just open-sourced something we’ve been quietly running in production: *hyprsqrl is a self-hostable bank. Think Revolut (if you know it), but every line of code is MIT/AGPL, you can run it on your own box, and the crypto bits stay hidden under the hood. --- ### Why we built it Moving money between USD and EUR still means wire fees, surprise freezes, and “call your bank” hoops. Fintechs like Revolut help—until their pricing changes or a regulator knocks. hyprsqrl aims for the resilience of self-hosting *without* forcing users to study crypto. Two…

Kekkai – Interactive security triage in the terminal▲6
Hey HN, As an AppSec engineer, I’ve spent a lot of time running and tunning open-source security scanners like Trivy, Semgrep, Gitleaks and Dojo. What I have found is that running them is easy, reviewing the results, not so much. Each tool outputs different JSON, false positives pile up, and CI either becomes noisy or blocks everything. So I built Kekkai (formerly Hokage), a small open-source CLI that wraps these scanners and focuses specifically on human triage. Kekkai runs the scanners in isolated Docker containers, normalizes their outputs into a single format, and provides an interactive…

We're building a search engine for GCP▲9
Hi HN, I previously wore SWE/SRE hats on GCP. Later, I was on the other side, managing thousands of machines. The friction points of onboarding and operating cloud systems are personal problems to me. I’ve found it hard to keep track of all the random cloud resources floating around, especially as my team’s assets proliferated. Occasionally, there is a resource affecting an outage but no one remembers where it is. I am constantly frustrated by existing tooling. APIs can work, after you’ve navigated the byzantine documentation, but I often find myself doing ad-hoc tasks which are best…

Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)
