   EnvKey 2.0 – End-To-End Encrypted Environments (now open source)▲225

   Hey HN, I'm so happy to finally show you all this release after years of hard work. I posted the first version of EnvKey to HN back in 2017 (https://news.ycombinator.com/item?id=15330757), then went through YC in W18 (https://news.ycombinator.com/item?id=16569534). EnvKey is an end-to-end encrypted configuration and secrets manager. It protects your organization's API keys, encryption keys, credentials, and other secrets, and makes it easy to run servers, scripts, tests, and everything else with the latest config. It also helps you avoid duplication in your…

   Enc – A modern and friendly CLI alternative to GnuPG▲90

   Enc is a CLI tool for encryption, a modern and friendly alternative to GnuPG. It is easy to use, secure by default and can encrypt and decrypt files using password or encryption keys, manage and download keys, and sign data. Our goal was to make encryption available to all engineers without the need to learn a lot of new words, concepts, and commands. It is the most beginner-friendly CLI tool for encryption, and keeping it that way is our top priority.

    keychains.dev▲177

    Hi HN — I’m a heavy OpenClaw user and, like many others, I’ve been thinking about how to give these new “unleashed” agents secure access to my accounts. Agents need API access to be useful. But API keys are long-lived secrets. And agents are not secure environments. So I built something for myself that quickly turned into a product: keychains.dev. The idea is simple: agents never see raw credentials. With Keychains.dev: • Agents make API calls via a drop-in replacement for curl or JavaScript’s fetch() • They use template variable names instead of embedding credentials • The request is…

    Phase – open-source encryption and key management for developers▲9

    Hello HN! We are developers and security researchers making tools for developers to encrypt data at an application level while maintaining sole control of their keys. We believe that data should always be encrypted unless it is part of an active computation. Encryption is relatively easy, but key management is challenging. There are plenty of encryption tools and SDKs that are out there (Hashicorp Vault, AWS KMS etc.) but we are focusing on ease and speed of implementation, developer experience and self custody of keys. A few months ago, we quit our jobs and started full time on Phase. So…

    Voiden – an offline, Git-native API tool built around Markdown▲48

    Hi HN, We have open-sourced Voiden. Most API tools are built like platforms. They are heavy because they optimize for accounts, sync, and abstraction - not for simple, local API work. Voiden treats API tooling as files. It’s an offline-first, Git-native API tool built on Markdown, where specs, tests, and docs live together as executable Markdown in your repo. Git is the source of truth. No cloud. No syncing. No accounts. No telemetry.Just Markdown, Git, hotkeys, and your damn specs. Voiden is extensible via plugins (including gRPC and WSS). Repo:…

    Open-Source Data Anonymization for Developers▲13

    Hey HN, we're Evis and Nick from Neosync (https://www.github.com/nucleuscloud/neosync). Since we last introduced Neosync on HN 4 months ago, we’ve made a lot of progress and we’re excited to be launching several new features. As a reminder, Neosync is an open source platform that helps developers anonymize production data, generate synthetic data, subset it and sync it across their environments for better testing, debugging and developer experience. We do all of this while handling referential integrity. Whether you have primary keys, foreign keys, unique constraints,…
