Zero-Knowledge

Encryption

It's like putting something in a box and locking it. The company stores the box, but doesn't have the key.

Definition

A security model where the service provider has no access to your data, not even the encrypted content.

In plain English It's like putting something in a box and locking it. The company stores the box, but doesn't have the key.

Why this matters

Zero-knowledge protects you even if the provider is hacked or asked to hand over your data.

Example

Services like Proton Drive and Standard Notes use zero-knowledge encryption to protect files and notes.
