vucoin

Node.js module to access ucoin server through its HTTP API.

Usage

var vucoin = require('vucoin');

// Wether we want authentified responses, or not (as it is costly)
var authentication = true;

// If we want authentified responses, give response signature in callbacks too
var giveSignatures = true;

vucoin('localhost', '8081', authentication, giveSignatures, function (err, node){

  // Public key imported, exchanges are signed
  node.pks.lookup('John Carter', function(err, keys, signature){
    // Results
  });
});

Here, vucoin will ask remote his public key for authentication, but it can be manually given too:

var pubkey = fs.readFileSync('/path/to/key.pub', 'utf8');
vucoin('localhost', '8081', pubkey, function (err, node){
  // Public key imported, exchanges are signed
});

Public keys

var key = fs.readFileSync('/path/to/key.pub', 'utf8');
var sig = fs.readFileSync('/path/to/signature', 'utf8');

node.pks.add(key, sig, function(err, key){
  // Key is now updated
  var fpr = key.fingerprint;
  var name = key.name;
});

node.pks.lookup('John Carter', function(err, keys){
  // Results
});

var merkleOpts = {};

node.pks.all(merkleOpts, function(err, json){
  // Results
});

node.ucg.peering.get(function(err, json){

  // Results
});

node.ucg.peering.peers.upstream.of('0124A69D94F4101EFAD727A73A8A49A2960C6826', function(err, json){
  // Results

node.ucg.peering.peers.downstream.get(function(err, json){
  // Results

node.ucg.peering.peers.downstream.of('0124A69D94F4101EFAD727A73A8A49A2960C6826', function(err, json){

Command Line

Installation

vucoin may be installed globally via

$ sudo npm install vucoin -g

Forge

uforge is a CLI to forge HDC documents, ready-to-send data for uCoin servers.

Requirements

Node.js

uforge is relying on vucoin CLI, itself powered by Node.js v0.10+, so you need it installed first. Here is an example for Ubuntu installation:

$ sudo apt-get update
$ sudo apt-get install python-software-properties python g++ make
$ sudo add-apt-repository ppa:chris-lea/node.js
$ sudo apt-get update
$ sudo apt-get install mongodb nodejs

You can find the installation of Node.js for other distribution on this GitHub document.

GPG

uforge also relies on gpg, as uCoin software uses it almost everywhere.

Here is an example for Ubuntu installation:

$ sudo apt-get install gpg
