   Keeper – embedded secret store for Go (help me break it)▲64

   Keeper is an embeddable secret store (Argon2id, XChaCha20-Poly1305 by default). Four security levels, audit chains, crash-safe rotation. Vault is overkill for most use cases. This is for when you ge paranoid about env and need encrypted local storage that doesn't suck. No security through obscurity, hence, It's still early, so now's the best time to find weird edge cases, race conditions, memory leaks, crypto misuse, anything that breaks. The README has a full security model breakdown if you want to get adversarial.

    AxKeyStore▲31

    Hi HN, I built AxKeyStore, an open-source CLI tool for managing secrets that uses your own private GitHub repository as encrypted storage. The idea is simple: → All encryption happens locally. → Secrets are stored as encrypted blobs in your private repo. → GitHub is treated as untrusted storage. → No plaintext secrets ever leave your machine. → No plaintext secrets are stored on disk. Most secret managers either require a hosted backend, a self-hosted server, or trusting a SaaS provider. I wanted something that: → Requires zero infrastructure → Uses tooling developers already have → Keeps…

    We built an end-to-end encrypted alternative to Notion▲7

    Hello HN, Over the last year we've been building snote.app, a Privacy focused, End-to-End Encrypted alternative to Notion. You can write, plan, collaborate and get organized - it allows you to take notes, store files, add tasks, manage projects & more. Whether you're working solo or in a team. We are hoping to use this post as an opportunity to collect feedback from fellow hackers. If there's anything we can do better, please let us know
