Donkey Bridge Lite – secure passwords

About

I built Donkey Bridge Lite, a lightweight app for generating secure passwords. The app works entirely offline, and passwords are deterministically derived from a user-defined "CryptoLine" (master key) plus a numeric notation. - The CryptoLine is **kept secret in the user's mind**, never stored on the device. - The numeric notation controls **character selection and order**, allowing reproducible passwords while keeping them unpredictable to anyone without the CryptoLine. Key security points: - Offline generation → no network exposure - Deterministic, ideal for reproducible credentials - Post-Quantum practical security → without the secret CryptoLine, passwords cannot be computed even with quantum computers - Minimal interface, privacy-focused, optional open-source Thanks!
