Deadbolt is a cross-platform file encryption application designed to protect personal documents and folders with a password. It provides a straightforward graphical interface that allows users to encrypt or decrypt files without configuring complex security settings. The application uses AES-256-GCM encryption to protect data and verify its integrity. Newer file formats derive encryption keys from passwords using Argon2id. Encrypted files can be transferred between Windows, macOS, and Linux and decrypted using compatible Deadbolt installations. A separate command-line interface supports terminal workflows and scripted operations. Users can encrypt individual files or entire folders through either interface. Versioned encrypted file headers preserve compatibility with older formats. Built with Electron, Deadbolt provides desktop packages for major operating systems.
