Show HN: CyberVault – A Local-Only Password Manager in C#"

2 CyberNilsen 0 5/28/2025, 5:26:58 PM github.com ↗

Hi HN,

My friend and I built CyberVault, a lightweight password manager written in C#. It's designed for people who want full local control — no cloud sync, no accounts, and no third-party dependencies.

It runs as a standalone Windows app and stores everything in an encrypted vault on your machine. We built it out of frustration with cloud-based managers and a desire for simplicity and transparency.

Features: - Fully local storage (encrypted AES-256 vault file) - No remote sync or cloud - WPF GUI, no server setup needed - Experimental Chrome extension for autofill - Open source (MIT-licensed)

It's still in active development, and we’re looking for feedback on: - Encryption/security model - UX/UI suggestions - Feature ideas - Help with browser extension
