About Lockbox
Lock files with a password, so only someone with the password can open them. Everything happens in your browser: nothing is uploaded, and Yuzool never sees a file or a password. Drop in pictures, PDFs, documents or a whole folder, type a password or tap Make one for me for five random words, and Lockbox locks them with AES-256 into one box. Send the small .lockbox file, which opens on yuzool.com/lockbox on any phone or computer, or a self-opening file that unlocks itself in any browser with no website and no internet. For a short secret, such as a Wi-Fi password or a door code, Lock a note puts it inside a link that asks for the password. Unlocking shows pictures, PDFs and text before you save them, and Save all gives you a zip. A wrong password says so, and a box that has been changed or cut short refuses to open.
