Can I encrypt Google Drive files before downloading?

Yes. AstoundDrive encrypts your Google Drive folder contents with AES-256 before saving the ZIP to your device. The encryption happens locally in your browser.

Is AES-256 encryption secure?

AES-256 is the encryption standard used by governments, banks, and military organizations. With a strong password, it is computationally infeasible to break.

Does AstoundDrive see my encryption password?

No. Your password never leaves your device. All encryption happens locally in your browser using the Web Crypto API. AstoundDrive has zero access to your password or file contents.

How AstoundDrive Encrypts Your Files

AES-256 Encryption Standard

AstoundDrive uses AES-256 — the same encryption standard used by governments, banks, and military organizations worldwide. This is not a simple password lock; your file contents are mathematically scrambled using your password as the encryption key.

100% Local Processing

Encryption happens entirely within your browser using the Web Crypto API. Your password and file contents never leave your device. No data is transmitted to any external server — not even AstoundDrive's own servers.

Password Strength Feedback

AstoundDrive includes a built-in password strength meter that evaluates your password in real-time. This helps you choose a strong password that will withstand brute-force attacks.
