Bitcore - Key generation

gistfile1.txt

var bitcore = require('bitcore');
bitcore.buffertools.extend();

var k1 = new bitcore.Key.generateSync();
var pk1 = k1.private.toHex(); // save private key

// Load Key:
var k = new bitcore.Key();
var pkshex = 'b7dafe35d7d1aab78b53982c8ba554584518f86d50af565c98e053613c8f15e0'; // the saved key

k.private = new Buffer(pkshex).fromHex();
k.regenerateSync();

// Address From Key:
var hash = bitcore.util.sha256ripe160(k.public);
var version = bitcore.networks.livenet.addressVersion;
var addr = new bitcore.Address(version, hash).toString();
