What is Zero-Knowledge Encryption?

The infrastructure of absolute digital privacy.

In the digital age, trust is often a liability. Traditional cloud services store your data and your keys, meaning they (or any attacker who breaches them) can read your private information. Zero-Knowledge Encryption changes that fundamental flaw.

The Core Principle

The "Zero-Knowledge" protocol means that the service provider has zero technical ability to access the data stored on their servers. At Zero Lock, your master key never leaves your local hardware. When you "save" a password, it is encrypted locally using AES-256 before being transmitted as undecipherable ciphertext.

Why it Matters

  • No Data Breaches: Even if our databases were compromised, the attackers would find nothing but mathematical noise.
  • Privacy by Design: We physically cannot sell your data or hand it over to third parties because we don't have it.
  • Client-Side Sovereignty: You are the only person on Earth with the key to your vault.

Zero Lock isn't just a tool; it's a fortress for your digital identity.
