A secure wire protocol powering a decentralized overlay network for apps and devices
Quote
The telehash protocol enables any app or device to establish private communication channels over a network. The following combination of features in telehash offers distinctive advantages to application developers:
- all channels are encrypted all the time - there is no unencrypted mode
- because each application instance or device generates its own public/private keypair, they cannot be impersonated and security is not dependent on trust in certificate authorities
- addresses are generated from public key fingerprints, not centrally managed as with IP addresses
- routing is based on a globally distributed hash table (DHT), no central authority or managed heirarchy
- the dual JSON/binary packet format is extremely flexible while remaining developer-friendly
- channels can be reliable (like TCP) or unreliable (like UDP), and make use of HTTP, WebRTC, and other existing technologies
- existing application protocols such as NNTP and XMPP can re-use telehash as a secure transport layer
- although telehash apps can run over the current Internet, bindings to Bluetooth, IEEE 802.15.4, and other low-layer transports are also on the way
