I Built a Clipboard Manager for Linux with AES-256 Encryption — DotGhostBoard v1.4.0 Eclipse

A deep dive into building Eclipse — the security layer of DotGhostBoard: AES-256-GCM encryption, master password lock screen, stealth mode, secure delete, and app filtering. Full code walkthrough. Watch the 1-minute overview: 👻 DotGhostBoard v1.4.0 — Eclipse TL;DR — I built a clipboard manager for Linux (PyQt6 + SQLite) and just shipped its security layer: AES-256-GCM encryption, a master password lock screen, per-item secret toggle, stealth mode, secure file deletion, and app-level capture filtering. Zero telemetry. Zero Electron. 100% Python. Background — Why Another Clipboard Manager? Every clipboard manager I tried on Kali was either too heavy (Electron), too basic, or required a network connection. I wanted something that: Runs lean on Kali Linux with no browser runtime Captures text, images, and video paths automatically Has a proper security layer — not just a toggle So I built DotGhostBoard as part of my DotSuite toolkit. It's been through four versions: Version Codename Focus
