CLAIMED [Bounty] BTC (negotiable) to write PHP script to generate BTC addresses.

[Tungsten]

I've build Electrum-based open source Wordpress plugin that allows anyone to build 100% secure, hacker proof, no middlemen involved online stores allowing to sell anything for bitcoins or dollars:
https://wordpress.org/plugins/bitcoin-payments-for-woocommerce/

It is based on Electrum Master Public Key (MPK).
The problem is that Electrum 2.x changed the MPK algorithm and PHP-based MPK-to-bitcoin-address code (that I hired someone to write) no longer works.

I need to adjust existing (or create new) PHP code to generate bitcoin addresses from both Electrum 1.x and Electrum 2.x Master Public Keys.

Download plugin sources from here: https://wordpress.org/plugins/bitcoin-payments-for-woocommerce/ .
The current code that does it for Electrum 1.x is located within the file: bwwc-mpkgen.php, function:
function BWWC__MATH_generate_bitcoin_address_from_mpk ($master_public_key, $key_index)
{ ... }
Feel free to use it as a reference.

I need to create function: BWWC__MATH_generate_bitcoin_address_from_mpk2 ($master_public_key_v2, $key_index)
that can generate bitcoin addresses using Electrum 2.x Master Public Key in a decently performing way (not slower than 1 address per second on an average machine).

Can pay in bitcoins or dollars.

I would advise you to try out this package and execute openssl_pkey_new(); to generate a private/public key set.

It works just as https://www.bitaddress.org


Here's the complete array in brief :

Code:

<?php

//== Determine path
$ssl_path = getcwd();
$ssl_path = preg_replace('/\\\/','/', $ssl_path);  // Replace \ with /

//== Create a configuration array containing path to openssl.cnf 
$config = array(
"config" => "$ssl_path/openssl.cnf"
);

//=== Create data array for certificate information
$dn = array(
   "countryName"            => "UK",
   "stateOrProvinceName"    => "Cambridge",
   "localityName"           => "Cambs",
   "organizationName"       => "UniServer",
   "organizationalUnitName" => "Demo",
   "commonName"             => "localhost",
   "emailAddress"           => "me@example.com"
);

//=== Generate a new private (and public) key pair
$privkey = openssl_pkey_new($config);

//=== Generate a certificate signing request
$csr = openssl_csr_new($dn, $privkey, $config);

//== Create a self-signed certificate valid for 365 days
$sscert = openssl_csr_sign($csr, null, $privkey, 365, $config);

//== Create key file. Note no passphrase
openssl_pkey_export_to_file($privkey,"server.key",NULL, $config);

//== Create server certificate 
openssl_x509_export_to_file($sscert,  "server.crt",  FALSE );

//== Create a signing request file 
openssl_csr_export_to_file($csr, "server.csr");
?>

Moreover, there's an Electrum based WordPress plugin but I don't recommend using it though.

Congratulations to nearion for delivering exceptional quality code and winning the bounty.

I will be updating BitcoinWay - Bitcoin Payments for WooCommerce wordpress plugin soon to support both Electrum 1.x and Electrum 2.x Master Public Keys.

This plugin (in conjunction with free WooCommerce plugin) allows anyone to build online stores to securely accept payments in bitcoins (as well as in any other currency).
Secure means - your online store is 100% secure from any kind of hacking attacks without relying on any middleman or any third party service provider.

Secure also means - if your online store will be hacked and cracked and infested with malware and all passwords will be compromised and stolen - you will not lose any bitcoins - thanks for Electrum master public key algorithm that allows to generate receive-only bitcoin addresses without need of knowing private keys.

Even before I implemented this new update - you may use Bitcoin Payments for WooCommerce wordpress plugin today with Electrum 1.x.

Thanks to bitcointalk forum and to nearion.

Really? Can you show me the proof via pm regarding his "exceptional" quality code?

Because, as far as I noticed, he's a brand new member.

But congratulations to him if he has really contributed something "exceptional".

So being a new forum member makes it impossible to do quality work?

I tested code for 2 days before granting bounty and confirming it functions as desired.
Regarding code - keep an eye on the upcoming updates to the plugin - all new code will be there.

Alert here once you have updated the wordpress plugin. Thanks.
