We use the Galois/Counter Mode (GCM) for AES, providing both high-speed encryption and data integrity verification in a single pass.

Zero-Knowledge

We have no way to recover your data if you lose your password. We store zero data about your encryption sessions.

No Server Uploads

Your bandwidth is saved. Only the initial page load is required. All processing happens on your own hardware.

Knowledge Base

Frequently Asked Questions

Is it really safe to encrypt in the browser?

Yes. Modern browsers provide the Web Crypto API, which uses highly optimized, hardware-accelerated subroutines for encryption. This is the same underlying technology used by secure banking and communication apps.

Can DigitalChests see my password?

Absolutely not. The password field is processed locally within the React application logic. It is never sent over any network request.

Why is there a wait time?

To keep this professional tool free for everyone, we use a brief processing period to maintain our services through platform advertisements. This also ensures that large files have enough time to be processed by your CPU gracefully.
