DHT-ID generator and operator, designed with circular Id namespaces in mind, used in
webrtc-explorer. Currently only supports 48 bits, but I'm happy to make accept PR that make it Id size agnostic.
- Uses sha1 to guarantee that ID's are generated with an uniform distribution
- Runs in Node.js and in the browser
- Respects the natural circular ID namespace DHT are known to use (meaning that there is no ID higher than 48 bits)
How to use
var Id = require('dht-id); var idA = new Id(); // generates a new random Id with 48 bits length var idB = new Id(<value to generate the Id from>); // generates an Id based on the value, same value always generates same Id idA.toHex(); // returns the hex value of the Id in a string idA.toDec(); // returns the dec value of the Id in a number idA.next(); // basically this id + 1, useful to send to Sucessor Id.spin(); // returns an id larger than the max possible in Hex, useful when the message has to spin the ring Id.hash(content); // convinient way to find the Id of a content and guarantee that it has our ideal id length
