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

In plain words
Keeper is an embeddable secret store for Go applications that encrypts sensitive data locally using Argon2id and XChaCha20-Poly1305 by default. It offers four security levels, audit chains, and crash-safe key rotation as a lightweight alternative to full vault solutions. Designed for developers who need encrypted local storage without complexity, Keeper is in early development and actively seeking security testing, including identification of edge cases, race conditions, memory leaks, and cryptographic issues. The project includes a detailed security model documentation.

- KAKeepr – A Secure and Offline Open Source CLI Password ManagerNov 2025 · ▲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…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
