tenderkeys.js

A module for creating bip39 mnemonic, ed25519 key pair and ripemd160 address for Tendermint and Hyperledger Burrow

Example:

var TenderKeys = require('./index');
var tenderKeys = new TenderKeys;

var mnemonic = tenderKeys.generateRandomMnemonic();
var seed     =  tenderKeys.generateSeed(mnemonic);
var keyPair  = tenderKeys.generateKeyPair(seed);
var address  = tenderKeys.getAddressFromPubKey(keyPair.publicKey);

console.log("mnemonic    :" + mnemonic);
console.log("private key :" + keyPair.privateKey);
console.log("Public key  :" + keyPair.publicKey);
console.log("address     :" + address);

let data = '{"chain_id":"BurrowChain_2A0FC2-4F8BA9","tx":[1,{"inputs":[{"address":"6AE5EF855FE4F3771D1B6D6B73E21065ED7670EC","amount":1000,"sequence":8}],"outputs":[{"address":"D7572DA8389D0C3AA64FC8709CA853AFE24F4260","amount":1000}]}]}';
let privKey = 'C01E3035C40C2FF009791C36755848F77EA9FAD484E4A38A17355C72A2C5EDB81474C7654BD711B910F48561FCEC85BC5FAE01B1D209CDF6B60D10F141EC7D5B';
let signature = tenderKeys.sign(privKey,data);
console.log("signature :"+signature);
