How to Generate Address and Private Key (WIF) for 3rd Party Coins Using Passphrase

While this guide is intended for Notary Node operators, other users may find it useful too.

Never enter your Notary Node's passphrase into any other computer/server other than your node itself for security purposes.

For Notary Nodes, we will need Compressed Public Key as pubkey, Compressed WIF as private key and Compressed Address as the public address.

Install dependencies

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install git php-cli php-gmp php-mbstring

Steps

git clone https://github.com/DeckerSU/komodo_scripts
cd komodo_scripts
git submodule init
git submodule update --init --recursive

  • Open genkomodo.php for editing with nano genkomodo.php

  • To get generate private keys for other coins using your passphrase, change the value on the line $passphrase = "myverysecretandstrongpassphrase_noneabletobrute". Change only the content inside "" i.e., replace myverysecretandstrongpassphrase_noneabletobrute with your passphrase.

  • Alternatively, to generate private keys for other coins using KMD private key, uncomment the following line, and replace the private key with your own. // $bitcoinECDSA->setPrivateKeyWithWif("Uqe8cy26KvC2xqfh3aCpKvKjtoLC5YXiDW3iYf4MGSSy1RgMm3V5");

  • Next, execute the command: php genkomodo.php to generate the private keys

  • Copy and import your private keys (Compressed WIF) into their respective chains, then delete your passphrase from genkomodo.php for security purposes.

Example Output

$ php genkomodo.php

             Passphrase: 'myverysecretandstrongpassphrase_noneabletobrute'

Private Key Conversion in Python

The python script below will return converted Private Keys for all coins with a known wiftype prefix (or a specific coin if set via runtime param). If the coin you need to convert is not yet available, you need to find the relevant values in the project's source code, e.g. https://github.com/KomodoPlatform/komodo/blob/810d308d0792a560f05937b7989b6868381c1dc8/src/chainparams.cpp#L197-L199 Then PR these values to https://github.com/KomodoPlatform/coins/blob/master/coins

Install Dependencies

sudo apt install python3-pip
pip install base58

Create Script

  • Open a file for editing with nano convert_private_keys.py and input the code below
#!/usr/bin/env python3
import sys
import requests
import hashlib
import base58
import binascii

if len(sys.argv) > 1:
    WIF = sys.argv[1]
else:
    print("\n")
    WIF = input('Enter Private Key: ')
print("\n")

coin_prefixes = requests.get("https://stats.kmd.io/api/info/coin_prefixes/").json()["results"]

if len(sys.argv) > 2:
    coin = sys.argv[2]
    if coin not in coin_prefixes:
        print(f"Error: {coin} not in coin_prefixes")
        sys.exit()
else:
    coin = ""

def double_sha(x):
    a = hashlib.sha256(binascii.unhexlify(x)).hexdigest()
    return hashlib.sha256(binascii.unhexlify(a)).hexdigest()

pk = binascii.hexlify(base58.b58decode(WIF))[2:-8]
pk_utf = pk.decode("utf-8")

for _coin in coin_prefixes:
    prefix = coin_prefixes[_coin]["hex"]["wiftype"]
    x_key = prefix + pk_utf
    full_key = x_key + double_sha(x_key)[:8]
    WIF = base58.b58encode(binascii.unhexlify(full_key)).decode('utf-8')
    if coin != "":
        if coin  == _coin:
            print(WIF)
            break
    else:
        print (f"{_coin: >18}: {WIF}")
  • Make the script executable with chmod +x convert_private_keys.py

Example Output

  • Run the script, and enter your private key when prompted.
$ ./convert_private_keys.py

Enter Private Key: L24bEAJSkFCdjoQNEcboWfJdsLGLmkBgfGb4TSHnbhEmU9jenaes
