    Library to assist in payment processing on Sumcoin. It first allows for generation of address according to the BIP44 standard.

    Bitcoin-js is used for deterministic public and private keys. Please see the BIP32 standard for more information (BIP32).

    Getting Started

    npm install --save sumcoin-segwit-payments

    Create a new wallet (DON'T DO THIS ON PRODUCTION):

    let segwitPayments = require('sumcoin-segwit-payments')()
    let keys = segwitPayments.generateNewKeys('really random entropy here')
    console.log(keys.xpub)
    console.log(keys.xprv)

    Generate an segwit deposit address from a public seed (xpub). This is useful if you are a hot wallet and don't store the private key. You will need to keep track of which path node you are on (increasing INT):

    let depositAddress = segwitPayments.bip44(keys.xpub, 1234) // for path m/49'/2'/0'/0/1234
    console.log(depositAddress)

    Get the private key for an address on a specific path:

    let privateKey = segwitPayments.getPrivateKey(keys.xprv, 1234) // for path m/49'/2'/0'/0/1234

    Get the public key from a private key:

    let address = segwitPayments.privateToPublic(privateKey) // for path m/49'/2'/0'/0/1234
    if(address === depositAddress){
      console.log('this library works')
    } else {
      console.log('better not use this library')
    }

    Get the derived xpub key from a hardened private key:

    let xpub = segwitPayments.getXpubFromXprv(xprv) // for path m/49'/2'/0'/0/1234

    Note: It is suggested to generate your Private key offline with FAR more entropy than the default function, then use getXpubFromXprv. You have been warned!
