Why this encryption tool is useful
Private by design
The tool runs in the browser with the Web Crypto API. Files are not uploaded to Envizion, so the workflow is fast and suitable for sensitive personal material.
Simple restore flow
Encrypted downloads keep the original file name and type inside the lock file metadata. Decrypt with the same password to get the original file back.
