   Lockenv – Simple encrypted secrets storage for Git▲105

   Hi! I got tired of setting up tools I can't explain to a team in a few words like sops or git-crypt, just to store few files with environment variables or secrets, so I built lockenv as a simple alternative. It's basically a password-protected vault file you commit to git. No gpg keys, no cloud, just lockenv init, set a password, and lock/unlock the secrets. This tool integrates with OS keyring, so you're not typing passwords constantly. Should work on Mac/Linux/Windows, but I tested it only on linux so far. I am not trying to replace any mature / robust solution, just…

   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…

    Retriever (https://retriever.corgea.io/), an open-source research project to help users receive secrets and sensitive information without needing a server in the middle. It works by using Public-key cryptography to coordinate the message sharing between the two devices. Read more on why we built it here: https://retriever.corgea.io/why.html

    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.

    Keypub.sh – OAuth for the terminal using SSH keys▲222

    Hi HN! I built KeyPub.sh to solve the problem of user verification for CLI applications. It's essentially OAuth for the terminal, but using SSH keys that developers and users already have. - No installation needed - works with existing SSH setup - Privacy-focused: users control what email info is shared - Simple email verification process - Free public service - Perfect for CLI app developers who don't want to build user verification Try it with: `$ ssh keypub.sh about` Source code: https://github.com/skariel/keypub

    Keepr – A Secure and Offline Open Source CLI Password Manager▲17

    Hi HN, I made Keepr, a simple offline CLI password manager for developers who prefer keeping secrets local and working entirely in the terminal. Everything is stored in an encrypted SQLCipher database, protected by a master password. A time-limited session keeps the vault unlocked while you work, so you don’t need to re-enter the password constantly. Keepr never touches the network. It includes commands to add, view, search, update, and delete entries, plus a secure password generator and clipboard support. Technical details: - AES-256 via SQLCipher - PBKDF2-HMAC-SHA256 (1.2M iterations) for…

    KeyEnv – CLI-first secrets manager for dev teams (Rust)▲5

    Hi HN, I built KeyEnv because I was tired of the "can you Slack me the Stripe key?" workflow. The problem: My team's secrets lived in a mix of Slack DMs, shared Google Docs, and .env files that definitely weren't in .gitignore at some point. Enterprise tools like Vault required more DevOps time than we had. Doppler was close but felt heavier than we needed. What KeyEnv does: keyenv init # link project keyenv pull # sync secrets to local .env keyenv run -- npm start # inject secrets, run command That's basically it. Secrets are encrypted client-side (AES-256-GCM) before leaving your machine.…
