Private, in-browser file encryption
The Files Encrypter uses the browser's native Web Crypto API to protect your files with AES-256. Pick a cipher mode — GCM (authenticated, recommended), CBC or CTR — enter a password, and your files are encrypted locally. Your password derives the key via PBKDF2-SHA256 with 250,000 iterations and a random salt; nothing is transmitted or stored. Decryption reverses the process using the same password.
Because it is fully client-side, it works offline and your data never touches a server.
