FAQ

      
Is this secure?
This tool uses the Web Crypto API with AES-GCM 256-bit encryption and PBKDF2 key derivation with 100,000 iterations. This is industry-standard encryption. However, the security depends entirely on your password strength — use a strong, unique password.

      
Is my data sent anywhere?
No. All encryption and decryption happens in your browser using the native Web Crypto API. Nothing is ever sent to a server.
