A file locker for USB drives. Keep documents encrypted behind a password and an authenticator code.
Client: DATAL Projects
Visit Live WebsiteDPLocker turns a USB stick into a private file locker. Documents are encrypted on the drive and open only after you enter a password and a 6-digit code from an authenticator app. It runs in its own window, works offline, and leaves nothing on the computer you plug into. Every file's contents and name are encrypted with AES-256-GCM using a key derived from your password with scrypt. The app works with any TOTP authenticator, locks out after repeated wrong attempts, and refuses to run from a computer's internal drive. It has a clean, Drive-style window with drag-and-drop uploads, list and grid views, search, Trash with restore, and light and dark themes. It can view, edit, or strip hidden metadata such as author, company, and edit history from Word, Excel, PowerPoint, OpenDocument, and PDF files. DPLocker is free and open source under the MIT license, available for Windows 10 and 11 as an installer or a portable build.
