Versions:
ChaBox is an offline file encryption application developed by Heshan Aisipai E-commerce Co., Ltd., currently available in version 1.0.0, the software's initial and only release to date. Positioned in the security and privacy category, the tool is built entirely on the industry-grade ChaCha20-Poly1305 cipher and operates with a 100% offline architecture, meaning no personal data is collected and no cloud services are required at any point during use. The application adopts a deliberately minimal interface designed for beginners, exposing only three core actions. The first is one-tap encryption and decryption, which allows a file to be dragged onto the workbench for instant protection or recovery. The second is Secure Diary, a Markdown-based notes feature in which text and images are encrypted directly on the device and lock automatically as soon as writing is finished. The third is Secure Delete (Wipe), which performs multiple random overwrites to guarantee complete data erasure. A built-in File Vault stores encrypted files in native folders, enabling users to move content seamlessly between the operating system's file manager, USB drives, or cloud storage while preserving the original directory hierarchy, a design that supports smooth cross-platform and cross-file-system portability. To encourage a "use → learn → master" progression, ChaBox also includes proactive defenses such as screen-capture and screen-recording blocking, idle auto-lock, and clipboard auto-cleaning, all of which run locally on the device. Typical use cases include protecting sensitive documents before transferring them to external drives or online storage, keeping private journals and images in an encrypted format, and permanently removing confidential files so they cannot be recovered. ChaBox version 1.0.0 therefore combines strong authenticated encryption with an approachable, beginner-friendly workflow for everyday privacy needs.
