How Browser Encryption Works

This tool uses the Web Crypto API built directly into your browser to encrypt and decrypt files. When you encrypt a file, it derives a strong key from your password using PBKDF2 and encrypts the data with AES-GCM. Because it happens entirely in your browser memory, your unencrypted files and passwords never leave your device.
