Independent Sync
Multi-device data synchronization is typically achieved by companies maintaining plaintext access to your data on their cloud servers. Torhun’s Independent Sync stack, however, tunnels the data through absolute darkness.
End-to-End Blind Communication (E2EE)
A note taken on your phone follows these protocols until it is reflected on your computer:
- Ed25519 Digital Signature: The client cryptographically signs the data before encryption.
- Merkle Tree Structure: Millions of files are compared using a Merkle-tree algorithm to rapidly identify modified blocks. The Torhun server merely shifts the positions of encrypted hash values on the branches without knowing the content.
- Resolver Principle: Even if your device is offline (Offline-First), the moment it reconnects, conflicts are resolved entirely on the secure local hardware, never on the server side.
Your data travels the globe, yet no network observer on Earth can decipher its contents.
