Products that do what Coze – cryptographic JSON messaging specification does
Coze is open source under the BSD 3 license, and the reference implementation is written in Go. You can play with Coze using the online tool (https://cyphr.me/coze). There is also the simple tool (https://cyphr.me/coze_verifier_simple/coze.html). This is an example coze: { "pay": { "msg": "Coze Rocks", "alg": "ES256", "iat": 1623132000, "tmb": "cLj8vsYtMBwYkzoFVZHBZo6SNL8wSdCIjCKAwXNuhOk", "typ": "cyphr.me/msg" }, "sig": "Jl8Kt4nznAf0LGgO5yn_9HkGdY3ulvjg-NyRGzlmJzhncbTkFFn9jrwIwGoRAQYhjc88wmwFNH5u_rO56USo_w" } Coze also defines a key format allowing…

I've been working on a C# implementation of Keyczar or months now. You can find it on github. http://jbtule.github.com/keyczar-dotnet/ It's feature complete, I've done a lot of unit tests, have about 90% code coverage, run various freely available static analysis, built it on linux and windows, but what I've really lacked is another person to actually look at the code. It's easy to make crypto mistakes, even when you know the common mistakes yourself. So I'd appreciate any comments, code reviews, thoughts, and issues. Thanks!

Hi everyone! So a couple of weeks ago I was building a chrome extension for crawling data and uploading it somewhere online for further exploration. I found myself struggling a lot with this as I found every solution I tried hard to implement (Firebase, Mongo Atlas, EC2). I mean I only needed a simple endpoint in which I was able to set and get JSON data with some key. In the end I made a small CRUD using Mongo, Sinatra, Puma, and Nginx. Then Chrome complained that my endpoint (raw IP) was not HTTPS so I bought a cheap domain and configured an SSL certificate into my server. I found this to…

fmsg is a message definition and protocol intended as an alternative to email and IM apps. Like email it's distributed – anyone can host a server for their domain. Unlike email, messages are binary, verifiable by all peers, and linked into a DAG using cryptographic hashes. Sender verification and message integrity are built into the protocol, so you get what email needs SPF/DKIM/DMARC for out of the box. The host implementation (fmsgd) is written in Go. There's a Docker compose setup to get a full stack running in minutes: https://github.com/markmnl/fmsg-docker…

The latest CLI releases from google and anthropic are sweet, we wanted build one that can run any model. mcp-use-cli lets you `/model` hop between providers instantly. npm i -g @mcp-use/cli && you're done What's cool: - BYOK (your keys, encrypted locally) - Slash commands for everything - MCP protocol support for custom tools - Works with OpenAI, Anthropic, Google, Mistral, Groq, local Ollama... The whole thing's TypeScript and open source. Built this on top of our Python + TS mcp-use libs, so it speaks MCP out of the box. You can hook up filesystem tools, DB servers, whatever you…

Hey, we built an open-source CLI in Go purposed to help you answer security questions across your cloud, code and runtime. It connects to your GitHub, GitLab, AWS, GCP, Azure & K8s using the credentials that are already in your shell, while limiting itself to read-only. The core innovation here is the trust boundary - our agent has a built-in code execution sandbox with no host or network access; it is exposed to an internal tool which we call an “action gate” that performs read-only HTTP requests to your own infrastructure. Since the cloud providers constantly expand actions and services,…

Hey HN, I built rawkit.dev, a collection of browser-based developer utilities. No ads, no signups, no tracking. Everything processes client-side — your data never touches a server. The tools: - JSONForge: JSON editor with tree/graph views, diff, transform, JQ-style queries, format conversion - SQLSandbox: SQLite via WASM — import CSVs, write SQL, join across files - Regexplorer: Regex builder with live matching, plain English mode,nmulti-language export - SiftLog: Log file viewer with auto-detection, severity filtering, regex search, timeline - Tabulate: CSV/TSV viewer with…

I built GoSMig for my own projects and open-sourced it in case it helps others. It’s a tiny generic library (no external deps except golang.org/x/term) for writing SQL migrations in Go with compile-time checks. It supports transactional and non-transactional migrations, rollback, status, version, and a small CLI handler so you can ship your own migration binary. Why another migrator? - Minimal API, no DSL or file layout to learn - Type-safe via Go generics - Works with database/sql and sqlx out of the box - Should work with any db library (or wrapper) that implements some…

We've rolled out a feature for openbase.com that we think is a DX game changer for Node devs. Since the emergence of ECMA Script modules, it's been a continuous guessing game as to what kind of exports a package has. That's never really been discoverable without using a site like unpkg, or installing the package and inspecting package.json. Openbase now displays the ES Module support level (e.g. type of exports) on all of their package pages. We added this feature because our devs are some of the folks continually caught off guard by installing an NPM dependency only to find out it's…

Hello HN, I built this because I wanted to give Claude Desktop access to my Notion workspace without running a flaky local Python script via stdio. This is a Node.js/Express implementation of the Model Context Protocol (MCP) that uses SSE (Server-Sent Events) for transport. It’s designed to be stateless and deployable as a container (I'm hosting it on Apify, but it works anywhere with Node). The Stack: TypeScript + Express @modelcontextprotocol/sdk Zod for input validation Bearer Auth for security (since it exposes an HTTP endpoint) Capabilities: It allows the LLM to search pages,…

Please check out out project, Lite Engine[1], a Backend as a Service web application platform. We provide everything you need to rapidly prototype and deploy your single page applications: static file hosting for your html, css, javascript and other assets, a subdomain on our site, security with https, and a 'create your own API' with SQL over CORS and JSON. I think of this as "geocities with a CORS backend". For your backend we've developed a system we call API Queries. You'll define SQL queries, save them on the backend, then execute them with http post requests that return JSON responses.…

Hi HN, We’re the team at MyDecisive.ai, and today we’re giving developers a peek at Octant — point-and-click control and visibility for your OpenTelemetry. You've likely felt the pain of the "observability tax," especially if you manage K8S clusters. The modern standard is to instrument everything with OpenTelemetry, but piping all those rich OTLP logs, metrics, and traces straight to a SaaS vendor (Datadog, Splunk, Honeycomb) gets expensive fast. You end up paying massive ingestion and storage costs for noisy, low-value data just so it's searchable when something breaks. With Octant you get…

Hi HN! This Christmas I made `tysm`, a rust crates which simplifies using ChatGPT with Structured Outputs. Essentially you just tell it the rust type you want the output to conform to, and it handles creating the JSON Schema, passing it to ChatGPT's chat-completions API, and deserializing the response. Structured Outputs are very useful because they guarantee that the response will conform to whatever type you expect. I'm already finding my crate very useful since I love using Structured Outputs but I hate writing JSON Schemas myself. Technical details for rust heads: To generate the JSON…

wk provides users with a portable and flexible interface for managing their key chord mappings. Key chords can be built directly into the binary, read from "wks" script files, or even piped in from stdin with the same wks syntax. There is also a wks-mode package for Emacs (https://github.com/3L0C/wks-mode). I appreciate any feedback you might have about the project and hope you find it useful.

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…
