ChaBox

ChaBox is an open-source, free, no-sign-up, zero-preset offline file
security workstation for personal and professional use.

It supports local encryption, decryption, archiving, unarchiving, and
secure wipe, and does not rely on cloud services.

Core capabilities:
- Secure Note: write like a Markdown notebook with immersive editing
and live preview, while notes are automatically encrypted at rest.
- ChaCha20-Poly1305 authenticated encryption with streaming integrity checks.
- One-click smart encrypt/decrypt workflows for efficient file handling.
- Batch and directory governance for migration, backup, and auditing.
- Secure wipe to reduce plaintext residue risk.
