Zero-Knowledge Encryption
What It Means
Zero-knowledge encryption is a security framework that ensures only the intended users can access data, and no one else — not even the service provider — can decrypt it. Unlike traditional encryption models, where service providers still may hold the keys or backup access, zero-knowledge protocols eliminate that possibility entirely.
Why It Matters
Most platforms that claim to be secure still retain access to your content behind the scenes. They may encrypt in transit or at rest, but they hold the keys, giving them the ability (and liability) to access, analyze, or hand over your data. This creates unnecessary risk — from breaches to misuse to surveillance.
How UB System Implements It
At UB, zero-knowledge encryption is not a toggle. It's the default and only way we handle your data. Here's how it works:
- When you compose an email or upload a file, encryption begins immediately on your device.
- Your data is encrypted using your recipient's public key, ensuring only they can decrypt it using their private key.
- UB's infrastructure never receives or stores unencrypted content — not even temporarily.
- We do not store private keys, and we do not retain any recovery mechanism that would let us access your content, even in edge cases.
- This means even in the unlikely event of a server compromise or subpoena, your content remains completely unreadable to us or anyone else.
UB's Advantage:
Most providers encrypt for you. UB encrypts away from us — ensuring true ownership, total privacy, and zero backdoors.
