mx-bitcoin-address

Bitcoin addresses generator

Installation

npm i --save mx-bitcoin-address

Usage

var generator = require('mx-bitcoin-address');

var keys = generator.fromRandom();
//var keys = generator.fromString('your long password phrase here');
//var keys = generator.fromHex('0C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D');

console.log(keys.getPrivateKeyBuffer());
console.log(keys.getPrivateKeyWif());
console.log(keys.getPublicKeyBuffer());
console.log(keys.getCompressedPublicKeyBuffer());
console.log(keys.getAddress());

API

Note: generator throws PrivKeyLessCurveError if generated private key larger then
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364140 and PrivKeyGreaterZeroError if private key is 0.
It's rare cases, but you should wrap static methods in try catch:

var generator = require('mx-bitcoin-address');

function generateFromRandom() {
    try {
        return generator.fromRandom()
    } catch (e) {
        if (e instanceof generator.PrivKeyGreaterZeroError || e instanceof generator.PrivKeyLessCurveError) {
            return generateFromRandom();
        } else {
            return e;        
        }
    }
}
