常见问题
Quick answers.
›What happens if I forget my password?
The data is unrecoverable. Because this is a privacy-first tool with no server-side storage, there is no 'reset' or recovery mechanism for lost passphrases.
›Is the encryption local or server-side?
All encryption and decryption occur locally on your device via your browser's Web Crypto API. Your files and passwords are never uploaded to any external server.
›Why is AES-GCM better than CBC mode?
GCM provides authenticated encryption, meaning it can detect if any part of the encrypted file has been tampered with or corrupted before decryption. Traditional CBC mode only provides privacy and requires a separate MAC for integrity.
›What is the file size limit?
The limit depends on your browser's available memory. For files larger than 1GB, we recommend using a dedicated desktop tool to avoid browser crashes or memory exhaustion.
