ChaBox

ChaBox is a 100% offline file encryption tool built on the industry grade ChaCha20-Poly1305 cipher. We intentionally adopt a minimal UI, exposing only three beginner friendly actions, - 1️. One‑tap encrypt/decrypt – drag a file onto the workbench to instantly protect or recover it. - 2️. Secure Diary – Markdown‑based notes where text and images are encrypted on‑device; they lock the moment you finish writing. - 3️. Secure Delete (Wipe) – multiple random overwrites guarantee complete data erasure. The built-in File Vault stores encrypted files in native folders, allowing seamless movement between the OS file manager, USB drives, or cloud storage while preserving directory hierarchy. This design ensures smooth cross-platform/file-system portability. To guide users through a “use → learn → master” loop, ChaBox adds proactive defenses, screen‑capture & screen‑record blocking, idle auto‑lock, and clipboard auto‑cleaning. All protection runs locally; no personal data is collected and no cloud services are required.
